刚接触struts
不久，公司又要我学spring
，然后把两者结合起来用。于是我在网上找了很多的有关struts+spring
的例子，但基本上都是struts+spring+hibernate
的，而我们公司不用hibernate
。后来，我就在struts
的基本上，再学习怎么把spring
加入的例子，然后根据它的原理重新编写一本书上用struts
实现的例子。
一、运行环境
1、eclipse-SDK-3.2
2、MyEclipse GA5.0
3、apache-tomcat-5.5.20
4、Strust1.2
5、Spring1.2
二、该工程所需文件
1、index.jsp
2、login.jsp
3、reinput_blank.jsp
4、reinput_error.jsp
5、success.jsp
6、LoginActio.java
7、LoginForm.java
8、struts-config.xml
9、applicationContext.xml
三、步骤
1、建工程
创建一个名为Welcome_SS的Web Project
File -> New -> Project -> Web Project , “next” Project Name：”Welcome_SS” ,“finish”;
2、导入struts包
选择Welcome_SS工程，右键->Myeclipse (或选菜单栏上Myeclipse) -> Add struts Capabilities……,选择struts1.2，然后finish;
3、导入spring包
选择Welcome_SS工程，右键->Myeclipse (或选菜单栏上Myeclipse) -> Add spring Capabilities……,在默认基础上，再选择Spring 1.2 AOP Libraries - <MyEclipse-Library>和Spring 1.2 Web Libraries - <MyEclipse-Library>，然后finish;
(为什么要选这两个，我也还没有弄清楚)
注：可能还要在lib文件夹下加几个spring包，
spring.jar,
spring-1.2.6.jar,
spring-aop.jar,
spring-beans.jar,
spring-context.jar,
spring-core.jar,
spring-orm.jar,
spring-remoting.jar,
spring-support.jar,
spring-web.jar,
spring-webmvc.jar
4、编写代码（页面及其所需的类）
Ø index.jsp
选择Welcome_SS工程下的WebRoot -> New -> JSP，取名为index.jsp，Finish;
输入以下代码
1
2 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

13 import org.apache.struts.action.ActionMapping;
14 import org.apache.struts.util.MessageResources;
15
16 import com.yourcompany.struts.form.LoginForm;
17
18 public class LoginAction extends Action {
19
20 private String message;
21
22 public String getMessage() {
23 return message;
24 }
25

33 HttpServletResponse response)
34 LoginForm userform = (LoginForm) form;
35 if(userform.getUsername().equals("")||(userform.getPassword().equals(""))){
36 return mapping.findForward("reinput_blank");
37 }
38 else if(userform.getUsername().equals("success")&&(userform.getPassword().equals("success"))){
39 request.setAttribute("message",getMessage()+userform.getUsername());
40 return mapping.findForward("success");
41 }
42 else{

8
9 public class LoginForm extends ActionForm {
10
11 /** username property */
12 private String username;

20 public String getUsername() {
21 return username;
22 }
23 public void setUsername(String username) {
24 this.username = username;
25 }
26 }
5、根据前一步的代码，进行配置文件的编写（struts-config.xml和applicationContext.xml）
选择Welcome_SS工程下的WebRoot -> WEB-INF -> struts-config.xml
输入下面代码：
1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">
3
4 <struts-config>
5 <data-sources />
6 <form-beans >
7 <form-bean name="loginForm" type="com.yourcompany.struts.form.LoginForm" />
8 </form-beans>
9
10 <global-exceptions />
11 <global-forwards />
12 <action-mappings >
13 <action
14 attribute="loginForm"
15 input="/login.jsp"
16 name="loginForm"
17 path="/login"
18 scope="request"
19 type="org.springframework.web.struts.DelegatingActionProxy">
20 <forward name="success" path="/success.jsp" />
21 <forward name="reinput_blank" path="/reinput_blank.jsp"/>
22 <forward name="reinput_error" path="/reinput_error.jsp"/>
23 </action>
24
25 </action-mappings>
26
27 <message-resources parameter="com.yourcompany.struts.ApplicationResources" />
28
29 <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
30 <set-property property="contextConfigLocation" value="/WEB-INF/classes/applicationContext.xml" />
31 </plug-in>
32
33 </struts-config>
34
35
选择Welcome_SS工程下的src -> applicationContext.xml
输入下面代码：
1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
3 <beans>
4 <bean name="/login" class="com.yourcompany.struts.action.LoginAction">
5 <property name="message">
6 <value>Welcome_</value>
7 </property>
8 </bean>
9 </beans>
10
6、Web Service（这里即Tomcat）布署及启动
(全面的可以参照我的另一篇随笔：Myeclipse中Tomcat的两种布署方式)
a.在apache-tomcat-5.5.20"conf下，找到server.xml，打开，在</Host>前面添加一句
<Context path="/wess" debug="0" docBase="C:\Documents and Settings\tt\workspace\Welcome_SS\WebRoot" reloadable="true"></Context>
注：C:\Documents and Settings\tt\workspace\Welcome_SS是该工程的存储路径。
b.在Myeclipse中的工具栏上找到一个像机箱似形状的按钮，点击，则打开服务器Tomcat.
7、运行
在IE 浏览器里输入http://localhost:8080/wess，即可运行！成功登陆的条件是用户名和密码都为success的时候。
