1、完整的注册和登录演示

   页面结构图

   所需要的 JavaBean


   新建工程，名称为：webwork

   拷贝webwork相关的类库文件到项目的 lib 目录下，具体的类库文件请从《速动画教程第二十三集》的源程序中拷贝
   刷新工程

   新建三个 JAVA 文件

   User.java 文件内容如下：
----------------------------------------------------------------------------------------------------
package com.test;

public class User {

private String userName;
private String userPwd;

public String getUserName() {
  return userName;
}
public void setUserName(String userName) {
  this.userName = userName;
}
public String getUserPwd() {
  return userPwd;
}
public void setUserPwd(String userPwd) {
  this.userPwd = userPwd;
}

}
----------------------------------------------------------------------------------------------------

LoginAction.java 文件，需要实现 com.opensymphony.xwork.Action 接口，内容如下：
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;

public class LoginAction implements Action {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public String execute() throws Exception {
  // 可以在这里调用Service层来进行验证，这里只验证用户名
  if (user.getUserName().equals("oksonic") && user.getUserPwd().equals("oksonic"))
   return this.SUCCESS;
  else
   return this.ERROR;
}

}
----------------------------------------------------------------------------------------------------

RegisterAction.java 文件，需要实现 com.opensymphony.xwork.Action 接口，内容如下：
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;

public class RegisterAction implements Action {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public String execute() throws Exception {
  System.out.println(user.getUserName());
  System.out.println(user.getUserPwd());
  return this.SUCCESS;
}

}
----------------------------------------------------------------------------------------------------

新建 xwork.xml 文件，此文件为 webwork 的配置文件，必须放到 src 目录下
----------------------------------------------------------------------------------------------------
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml" />
<package name="default" extends="webwork-default">
  <action name="login" class="com.test.LoginAction">
   
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="error" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <interceptor-ref name="params" />
  </action>
  <action name="register"
   class="com.test.RegisterAction">
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   <interceptor-ref name="params" />
  </action>
</package>
</xwork>
----------------------------------------------------------------------------------------------------
<action name="login" class="com.test.web.action.LoginAction"> 这一句为定义 action
执行 action 的路径为 /login.action

新建 jsp 文件

index.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<html>
<head><title>INDEX</title></head>
<body>
<a href="login.jsp">Login</a><br>
<a href="register.jsp">Register</a>
</body>
</html>
----------------------------------------------------------------------------------------------------

   login.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<html>
<head><title>Login</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<form name="login" action="login.action" method="post">
  Username:<input type="text" name="user.userName"><br>
  Password:<input type="password" name="user.userPwd"><br>
  <input type="submit" name="Submit"><br>
</form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

   register.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<html>
<head><title>Register</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<form name="register" action="register.action" method="post">
  Username:<input type="text" name="user.userName"><br>
  Password:<input type="password" name="user.userPwd"><br>
  <input type="submit" name="Submit"><br>
</form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

   ok.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<html>
<head>
  <title>OK</title>
</head>
<body>
  userName=<ww:property value="user.userName" />
  <br>
  userPwd=<ww:property value="user.userPwd" />
  <br>
  <a href="index.jsp">HOME</a>
</body>
</html>
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%> 使用 webwork 的标签来获取值，注意红色字体，需要有斜杆

   配置 web.xml 文件，文件内容如下：
----------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
  <servlet-name>webwork</servlet-name>
  <servlet-class>com.opensymphony.webwork.dispatcher.ServletDispatcher</servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>webwork</servlet-name>
  <url-pattern>*.action</url-pattern>
</servlet-mapping>
</web-app>
----------------------------------------------------------------------------------------------------

好了，进行第一段的测试

2、Model-Driven（模型驱动）

Model-Driven（模型驱动）的 Action 要求我们的 Action 实现 com.opensymphony.xwork.ModelDriven 接口，
它有一个方法：Object getModel(); 我们用这个方法返回我们的模型对象就可以了，也就是 User

修改 Action 加入 com.opensymphony.xwork.ModelDriven 接口，并创建 Object getModel() 方法
将表单中的 <input type="text" name="user.userName"> 改为 <input type="text" name="userName">
修改 xwork.xml 文件，增加 <interceptor-ref name="model-driven"/>

具体代码如下：

LoginAction.java 文件
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ModelDriven;

public class LoginAction implements Action,ModelDriven {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public String execute() throws Exception {
  // 可以在这里调用Service层来进行验证
  if (user.getUserName().equals("oksonic") && user.getUserPwd().equals("oksonic"))
   return this.SUCCESS;
  else
   return this.ERROR;
}

public Object getModel() {
return user;
}

}
----------------------------------------------------------------------------------------------------

RegisterAction.java 文件
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ModelDriven;

public class RegisterAction implements Action,ModelDriven {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public String execute() throws Exception {
  System.out.println(user.getUserName());
  System.out.println(user.getUserPwd());
  return this.SUCCESS;
}

public Object getModel() {
return user;
}

}
----------------------------------------------------------------------------------------------------

修改 xwork.xml 文件，此文件为 webwork 的配置文件，必须放到 src 目录下
----------------------------------------------------------------------------------------------------
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml" />
<package name="default" extends="webwork-default">
  <action name="login" class="com.test.LoginAction">
   
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="error" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <interceptor-ref name="model-driven"/>
   
   <interceptor-ref name="params" />
  </action>
  <action name="register"
   class="com.test.RegisterAction">
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   <interceptor-ref name="model-driven"/>
   <interceptor-ref name="params" />
  </action>
</package>
</xwork>
----------------------------------------------------------------------------------------------------
   注意：<interceptor-ref name="model-driven"/> 和 <interceptor-ref name="params" /> 的顺序一定要分先后

这时可以去掉 jsp 文件中 name 值中的对像名了，如：user.userName 可以改为 userName

   login.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<html>
<head><title>Login</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<form name="register" action="login.action" method="post">
  Username:<input type="text" name="userName"><br>
  Password:<input type="password" name="userPwd"><br>
  <input type="submit" name="Submit"><br>
</form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

   register.jsp 文件内容如下：
----------------------------------------------------------------------------------------------------
<html>
<head><title>Register</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<form name="register" action="register.action" method="post">
  Username:<input type="text" name="userName"><br>
  Password:<input type="password" name="userPwd"><br>
  <input type="submit" name="Submit"><br>
</form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

3、使用 JUnit 进行单元测试

新建一个 JUnit Test Case (LoginActionTest)，放到 test.com.test 包中，内容如下：
----------------------------------------------------------------------------------------------------
package test.com.test;

import java.util.HashMap;
import java.util.Map;

import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ActionProxy;
import com.opensymphony.xwork.ActionProxyFactory;
import com.test.LoginAction;

import junit.framework.TestCase;

public class LoginActionTest extends TestCase {

public void testExecute() throws Exception {
  Map params = new HashMap();
  params.put("user.userName", "oksonic");
  params.put("user.userPwd", "oksonic");
  Map extraContext = new HashMap();
  extraContext.put(ActionContext.PARAMETERS, params);

  ActionProxy proxy = ActionProxyFactory.getFactory().createActionProxy(
    "com.test", "login", extraContext);
  proxy.setExecuteResult(false);
  assertEquals(proxy.execute(), "success");

LoginAction action = (LoginAction) proxy.getAction();
assertEquals(action.getUser().getUserName(), "oksonic");
}

}
----------------------------------------------------------------------------------------------------
关于测试代码的详细解释请查看《WebWork教程》中的内容

新建一个 JUnit Test Case (RegisterActionTest)，放到 test.com.test 包中，内容如下：
----------------------------------------------------------------------------------------------------
package test.com.test;

import java.util.HashMap;
import java.util.Map;

import com.opensymphony.xwork.ActionContext;
import com.opensymphony.xwork.ActionProxy;
import com.opensymphony.xwork.ActionProxyFactory;
import com.test.LoginAction;

import junit.framework.TestCase;

public class LoginActionTest extends TestCase {

public void testExecute() throws Exception {
  Map params = new HashMap();
  params.put("user.userName", "aaa");
  params.put("user.userPwd", "bbb");
  Map extraContext = new HashMap();
  extraContext.put(ActionContext.PARAMETERS, params);

  ActionProxy proxy = ActionProxyFactory.getFactory().createActionProxy(
    "com.test", "register", extraContext);
  proxy.setExecuteResult(false);
  assertEquals(proxy.execute(), "success");

RegisterAction action = (RegisterAction) proxy.getAction();
assertEquals(action.getUser().getUserName(), "aaa");
}

}
----------------------------------------------------------------------------------------------------

新建一个 JUnit Test Suite ，这样就可以一次运行两个 test case 了，内容如下：
----------------------------------------------------------------------------------------------------
package test.com.test;

import junit.framework.Test;
import junit.framework.TestSuite;

public class AllTests {

public static Test suite() {
  TestSuite suite = new TestSuite("Test for test.com.test");
  //$JUnit-BEGIN$
  suite.addTestSuite(LoginActionTest.class);
  suite.addTestSuite(RegisterActionTest.class);
  //$JUnit-END$
  return suite;
}

}
----------------------------------------------------------------------------------------------------

直接进行测试（不需要启动服务），出现绿色条表示正常

4、配置表单验证

   注册的验证类型：在 src 目录下新建 validators.xml 文件，文件内容如下：
----------------------------------------------------------------------------------------------------
<validators>
    <validator name="required" class="com.opensymphony.xwork.validator.validators.RequiredFieldValidator"/>
    <validator name="requiredstring" class="com.opensymphony.xwork.validator.validators.RequiredStringValidator"/>
    <validator name="int" class="com.opensymphony.xwork.validator.validators.IntRangeFieldValidator"/>
    <validator name="date" class="com.opensymphony.xwork.validator.validators.DateRangeFieldValidator"/>
    <validator name="expression" class="com.opensymphony.xwork.validator.validators.ExpressionValidator"/>
    <validator name="fieldexpression" class="com.opensymphony.xwork.validator.validators.FieldExpressionValidator"/>
    <validator name="email" class="com.opensymphony.xwork.validator.validators.EmailValidator"/>
    <validator name="url" class="com.opensymphony.xwork.validator.validators.URLValidator"/>
    <validator name="visitor" class="com.opensymphony.xwork.validator.validators.VisitorFieldValidator"/>
    <validator name="conversion" class="com.opensymphony.xwork.validator.validators.ConversionErrorFieldValidator"/>
    <validator name="stringlength" class="com.opensymphony.xwork.validator.validators.StringLengthFieldValidator"/>
</validators>
----------------------------------------------------------------------------------------------------

要启动表单验证，需要增加一个拦截器，对 xwork.xml 文件进行修改，增加 <interceptor-ref name="validationWorkflowStack" />

代码如下：
   xwork.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml" />
<package name="default" extends="webwork-default">
  <action name="login" class="com.test.LoginAction">
   
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="error" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <result name="input" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <interceptor-ref name="model-driven"/>
   <interceptor-ref name="params" />
   <interceptor-ref name="validationWorkflowStack"/>
  </action>
  <action name="register"
   class="com.test.RegisterAction">
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="input" type="dispatcher">
    <param name="location">/register.jsp</param>
   </result>
   <interceptor-ref name="model-driven"/>
   <interceptor-ref name="params" />
   <interceptor-ref name="validationWorkflowStack" />
  </action>
</package>
</xwork>
----------------------------------------------------------------------------------------------------

修改 LoginAction、RegisterAction，使继承 ActionSupport 类
ActionSupport 类实现了数据校验错误信息、Action 运行错误信息的保存传递功
能。通过扩展 ActionSupport，LoginAction 即可携带执行过程中的状态信息，这
为之后的错误处理，以及面向用户的信息反馈提供了基础数据。

LoginAction.java 代码如下：
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.xwork.ModelDriven;

public class LoginAction extends ActionSupport implements Action,ModelDriven {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public Object getModel() {
return user;
}

}
----------------------------------------------------------------------------------------------------

RegisterAction.java 代码如下：
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.xwork.ModelDriven;

public class RegisterAction extends ActionSupport implements Action,ModelDriven {
// 必需进行初始化
private User user = new User();

public User getUser() {
return user;
}

public String execute() throws Exception {
  System.out.println(user.getUserName());
  System.out.println(user.getUserPwd());
  return this.SUCCESS;
}

public Object getModel() {
return user;
}

}
----------------------------------------------------------------------------------------------------

   修改页面，为了能够显示错误消息，需要使用 webwork 的标签来实现页面，代码如下：
   login.jsp
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<html>
<head><title>Register</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<ww:form name="test" action="login.action" method="POST">
            <ww:textfield label="Username" name="userName" required="true"/>
            <ww:password label="Password" name="userPwd" required="true"/>
            <ww:submit value="Submit"/>
     </ww:form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

   register.jsp
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<html>
<head><title>Login</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<ww:form name="test" action="register.action" method="POST">
            <ww:textfield label="Username" name="userName" required="true"/>
            <ww:password label="Password" name="userPwd" required="true"/>
            <ww:submit value="Submit"/>
     </ww:form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

建立验证规则

      对 LoginAction 进行验证规则的配置，需要新建一个配置文件，文件名以 “Action 的名称” + “-validation.xml”来命名，并保存到 LoginAction.java 文件所在的目录中
如：
       LoginAction-validation.xml

   代码如下：
   LoginAction-validation.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd">
<validators>
<field name="userName">
  <field-validator type="requiredstring">
   <message>You must enter a value for username.</message>
  </field-validator>
</field>
<field name="userPwd">
  <field-validator type="requiredstring">
   <message>You must enter a value for password.</message>
  </field-validator>
</field>
</validators>
----------------------------------------------------------------------------------------------------

   RegisterAction-validation.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd">
<validators>
<field name="userName">
  <field-validator type="requiredstring">
   <message>You must enter a value for username.</message>
  </field-validator>
</field>
<field name="userPwd">
  <field-validator type="requiredstring">
   <message>You must enter a value for password.</message>
  </field-validator>
</field>
</validators>
----------------------------------------------------------------------------------------------------

测试

5、国际化支持

Webwork 的国际化支持主要体现在两个部分：
1． UI-Tag
2． Validator

示例：读取 messages 资源中的 welcome 键值
<ww:i18n name="'messages'">
<ww:text name="'welcome'"/>
</ww:i18n>

在 src 目录下新建 messages_zh_CN.properties 文件，内容如下：
----------------------------------------------------------------------------------------------------
welcome=欢迎！{0}
----------------------------------------------------------------------------------------------------
这里的 “{0}”是为了加入参数而设定的，也可以再加入一个：welcome=欢迎！{0}{1}

   修改 ok.jsp ，让它在登录后显示欢迎字样
   ok.jsp
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<head>
  <title>OK</title>
</head>
<body>
  <ww:i18n name="messages">
   <ww:text name="welcome">
    <ww:param>
     <ww:property value="userName" />
    </ww:param>
   </ww:text>
  </ww:i18n>
  <br>
  userPwd=<ww:property value="userPwd" />
  <br>
</body>
</html>
----------------------------------------------------------------------------------------------------

验证部份使用的是对应 LoginAction.java 文件的一个指定的资源文件，和验证文件一样，
需要在 LoginAction.java 文件相同的目录下新建一个资源文件，文件名称为 LoginAction_zh_CN.properties

LoginAction_zh_CN.properties
----------------------------------------------------------------------------------------------------
error.username=用户名称必须输入！
error.password=密码必须输入！
----------------------------------------------------------------------------------------------------

RegisterAction_zh_CN.properties
----------------------------------------------------------------------------------------------------
error.username=用户名称必须输入！
error.password=密码必须输入！
----------------------------------------------------------------------------------------------------

   对验证部份进行修改
   LoginAction-validation.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd">
<validators>
<field name="userName">
  <field-validator type="requiredstring">
   <message key="error.username">You must enter a value for username.</message>
  </field-validator>
</field>
<field name="userPwd">
  <field-validator type="requiredstring">
   <message key="error.password">You must enter a value for password.</message>
  </field-validator>
</field>
</validators>
----------------------------------------------------------------------------------------------------
   使用 key 来指定资源文件中的键值

   RegisterAction-validation.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0//EN" "http://www.opensymphony.com/xwork/xwork-validator-1.0.dtd">
<validators>
<field name="userName">
  <field-validator type="requiredstring">
   <message key="error.username">You must enter a value for username.</message>
  </field-validator>
</field>
<field name="userPwd">
  <field-validator type="requiredstring">
   <message key="error.password">You must enter a value for password.</message>
  </field-validator>
</field>
</validators>
----------------------------------------------------------------------------------------------------

修改 login.jsp 和 register.jsp 加入 <%@ page contentType="text/html;charset=UTF-8" language="java"%> 以支持显示中文

   login.jsp
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<head><title>Login</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<ww:form name="test" action="login.action" method="POST">
            <ww:textfield label="Username" name="userName" required="true"/>
            <ww:password label="Password" name="userPwd" required="true"/>
            <ww:submit value="Submit"/>
     </ww:form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------

   register.jsp
----------------------------------------------------------------------------------------------------
<%@ taglib prefix="ww" uri="/webwork"%>
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<html>
<head><title>Register</title></head>
<body>
<table border=0 width=97%>
<tr><td align="left">
<ww:form name="test" action="register.action" method="POST">
            <ww:textfield label="Username" name="userName" required="true"/>
            <ww:password label="Password" name="userPwd" required="true"/>
            <ww:submit value="Submit"/>
     </ww:form>
</td></tr>
</table>
</body>
</html>
----------------------------------------------------------------------------------------------------
   测试

6、集成 spring
因为现在使用的 webwork 版本为 2.2.2，所以在集成 spring 的方式上和 2.1.x 以前的版本有所不同。

1) 修改 web.xml，为 Web 应用增加相应的 Spring ContextLoaderListener

    web.xml
----------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
  <servlet-name>webwork</servlet-name>
  <servlet-class>
   com.opensymphony.webwork.dispatcher.ServletDispatcher
  </servlet-class>
</servlet>
<servlet-mapping>
  <servlet-name>webwork</servlet-name>
  <url-pattern>*.action</url-pattern>
</servlet-mapping>
<listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
</listener>
</web-app>
----------------------------------------------------------------------------------------------------

2) 在 src 目录下新建 webwork.properties 文件，内容如下：

webwork.objectFactory = spring

这个文件非常重要，也是集成所必需的

3) 新增 Service 层的对像 IUserService、UserService

IUserService.java
----------------------------------------------------------------------------------------------------
package com.test.services;

import com.test.User;

public interface IUserService {

public boolean isValidUser(User user);

public boolean registerUser(User user);
}
----------------------------------------------------------------------------------------------------

UserService.java
----------------------------------------------------------------------------------------------------
package com.test.services;

import com.test.User;

public class UserService implements IUserService {

public boolean isValidUser(User user) {
  if (user.getUserName().equals("oksonic") && user.getUserPwd().equals("oksonic"))
   return true;
  else
   return false;
}

public boolean registerUser(User user) {
// 这里可以调用 DAO 层对像录入用户信息到数据库
return true;
}

}
----------------------------------------------------------------------------------------------------

4) 修改 xwork.xml
----------------------------------------------------------------------------------------------------
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd">
<xwork>
<include file="webwork-default.xml" />
<package name="default" extends="webwork-default">
  <action name="login" class="login">
   
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="error" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <result name="input" type="dispatcher">
    <param name="location">/login.jsp</param>
   </result>
   
   <interceptor-ref name="model-driven" />
   <interceptor-ref name="params" />
   <interceptor-ref name="validationWorkflowStack" />
  </action>
  <action name="register" class="register">
   <result name="success" type="dispatcher">
    <param name="location">/ok.jsp</param>
   </result>
   
   <result name="input" type="dispatcher">
    <param name="location">/register.jsp</param>
   </result>
   <interceptor-ref name="model-driven" />
   <interceptor-ref name="params" />
   <interceptor-ref name="validationWorkflowStack" />
  </action>
</package>
</xwork>

----------------------------------------------------------------------------------------------------

   5) 添加 spring 框架到项目中

   修改 applicationContext.xml 文件，加入 UserService 的配置信息
----------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean id="UserService" class="com.test.services.UserService" singleton="false"/>
<bean id="login" class="com.test.LoginAction" singleton="false" >
  <property name="userService">
   <ref bean="UserService"/>
  </property>
</bean>
<bean id="register" class="com.test.RegisterAction" singleton="false" >
  <property name="userService">
   <ref bean="UserService"/>
  </property>
</bean>
</beans>
----------------------------------------------------------------------------------------------------
   注意：红色字体内容要和 xwork.xml 文件中的内容相对应

6) 修改 Action

LoginAction.java
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.xwork.ModelDriven;
import com.test.services.IUserService;

public class LoginAction extends ActionSupport implements Action,ModelDriven {

// 必需进行初始化
private User user = new User();
private IUserService userService;

public User getUser() {
return user;
}

public String execute() throws Exception {
  // 可以在这里调用Service层来进行验证
  if (userService.isValidUser(user))
   return this.SUCCESS;
  else
   return this.ERROR;
}

public Object getModel() {
// TODO Auto-generated method stub
return user;
}

public void setUserService(IUserService userService) {
this.userService = userService;
}
}
----------------------------------------------------------------------------------------------------

RegisterAction.java
----------------------------------------------------------------------------------------------------
package com.test;

import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ActionSupport;
import com.opensymphony.xwork.ModelDriven;
import com.test.services.IUserService;

public class RegisterAction extends ActionSupport implements Action,ModelDriven {

// 必需进行初始化
private User user = new User();
private IUserService userService;

public User getUser() {
return user;
}

public String execute() throws Exception {
userService.registerUser(user);
return this.SUCCESS;
}

public Object getModel() {
// TODO Auto-generated method stub
return user;
}

public void setUserService(IUserService userService) {
this.userService = userService;
}
}
----------------------------------------------------------------------------------------------------

好了，进行最后的测试！
