1) 准备好如下jar包:
Oracle数据库的jar:
Ojdbc14.jar

struts2的jar:
commons-pool.jar
freemarker-2.3.8.jar
ognl-2.6.11.jar
struts2-core-2.0.11.jar
xwork-2.0.4.jar

struts2整合spring的jar:
struts2-spring-plugin-2.0.9.jar

Hibernate整合需要的jar:
commons-logging-1.0.4.jar

2) Jndi连接池配置(以Tomcat为例)
<Resource name="jdbc/ehangtian_jndi" auth="Container"
     type="javax.sql.DataSource"
    maxActive="100" maxIdle="30" maxWait="10000"
    username="EHT" password="eht"
    driverClassName="oracle.jdbc.driver.OracleDriver"
    url="jdbc:oracle:thin:@localhost:1521:Orcl"/>

3) 创建工程,加入准备好的jar包,
   通过IDE自动导入Spring,Hibernate框架,
   删除asm-2.2.3.jar这个冲突的Jar

创建model,dao,service,action,inteceptor包,
建立相应的类:
model类,dao类(继承HibernateDaoSupport),service类,Action类(继承ActionSupport),
interceptor类(依据拦截方式实现不同接口,常用的是实现MethodInteceptor环绕拦截接口);
 
 
4) 修改web.xml,加入Spring的装载器与Struts2.0的过滤器,编码过滤器:

<!-- Spring的装载器 -->
<listener>
    <listener-class>
         org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>
<!--ContextLoaderListener会去找contextConfigLocation这个参数的,选择spring的配置文件 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:/applicationContext.xml</param-value>
</context-param>

<!-- struts的过滤器 -->
<filter>
    <filter-name>struts2</filter-name>
     <filter-class>
         org.apache.struts2.dispatcher.FilterDispatcher
     </filter-class>
</filter>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 著名的Character Encoding filter,设置转换编码为gbk -->
<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>
        org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
    <param-name>encoding</param-name>
    <param-value>gbk</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>*.action</url-pattern>
</filter-mapping>

5) 创建struts.xml文档;

6) 在根目录下创建daoContext.xml,strutsContext.xml,serviceContext.xml,aopContext.xml;

7) 为上步创建的4个文档引入如下申明:

<?xml version="1.0" encoding="UTF-8"?>
<beans
   xmlns="
http://www.springframework.org/schema/beans"
   xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
http://www.springframework.org/schema/beans
  
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"></beans>

8) 创建JSP界面,建立表单,定义好表单的action属性(与下一步的<action/>配置的name属性匹配);

若要使用struts2标签,可引入<%@ taglib prefix="s" uri="/struts-tags" %>

9) 配置struts.xml:
<!DOCTYPE struts PUBLIC
     "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
     "
http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <!-- GBK编码 -->
    <constant name="struts.i18n.encoding" value="GBK" />
    <!--通过Spring管理Struts-->
    <constant name="struts.objectFactory" value="spring" />

    <package name="default" extends="struts-default">
       
        <action name="user" class="loginAction">
            <result name="input">/login.jsp</result>
            <result name="error">/login.jsp</result>
            <result name="success">/index.jsp</result>
            <interceptor-ref name="params"></interceptor-ref>
        </action>
       
    </package>
   
</struts>

10) 配置strutsContext.xml:

<!—未加AOP的配置-->
<bean id="loginAction" class="com.company.action.LoginAction" scope="prototype">
    <property name="userService" ref="userService" />
</bean>

11) 配置serviceContext.xml:

<!—未加事务的配置-->
<bean id="userService" class="com.company.service.UserService">
    <property name="userDao" ref="userDao"/>
</bean>

12) 配置daoContext.xml:

<!-- 数据源配置 -->
 <bean id="dataSource"
  class="org.springframework.jndi.JndiObjectFactoryBean">
  <property name="jndiName"
   value="java:comp/env/jdbc/ehangtian_jndi" />
  <property name="lookupOnStartup" value="false" />
  <property name="cache" value="true" />
  <property name="proxyInterface" value="javax.sql.DataSource" />
 </bean>

<!-- sessionFactory -->
<bean id="sessionFactory"
      class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource">
        <ref bean="dataSource" />
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">
            org.hibernate.dialect.Oracle9Dialect
        </prop>
        <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
    <property name="mappingDirectoryLocations">
         <list>
             <value>classpath:/com/company /model/User.hbm.xml</value>
         </list>
    </property>      
</bean>

<bean id="userDao" class="com.company.dao.UserDao">
       <property name="sessionFactory" ref="sessionFactory"/>
</bean>

13) 修改自动生成的applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans
       xmlns="
http://www.springframework.org/schema/beans"
       xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
      
       <import resource="aopContext.xml"/>
       <import resource="daoContext.xml"/>
       <import resource="serviceContext.xml"/>
       <import resource="strutsContext.xml"/>
</beans>

14) src下加入Log4J资源文件: log4j.properties

15) 可以开始写业务逻辑与数据库操作方法了.

Action类中获得各范围对象的方法:

1.获得Session对象:
Map sessionMap = ActionContext.getContext().getSession();
//将信息放入session中
sessionMap.put("user", "valid");

2.获得request对象         
HttpServletRequest request = ServletActionContext.getRequest();        
request.setAttribute("username", "helloworld");

3.获得response对象       
HttpServletResponse response = ServletActionContext.getResponse();               

Cookie cookie = new Cookie("username",this.getUsername());
//如果设置为负数,则为会话Cookie;
cookie.setMaxAge(1000);
response.addCookie(cookie);

字段驱动:

本例采用字段驱动, 它一般用在页面表单比较简单的情况使用.界面表单文本框的name属性必须采用user.username形式


模型驱动:

界面表单文本框比较复杂, 用普通java对象充当模型部分
struts.xml的action配置加上<interceptor-ref name="model-driven"/>
并且让Action类实现ModelDriven接口,重写getModel()方法

public Object getModel(){
    return user;
}
将JSP界面表单文本框的name属性的user.去掉


附加过滤器:

<!-- 容器负责session的开启和关闭 -->
<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>
        org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
    </filter-class><!-- singleSession默认为true,若设为false则等于没用OpenSessionInView -->
    <init-param>
        <param-name>singleSession</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>hibernateFilter</filter-name>
    <url-pattern>*.action</url-pattern>
</filter-mapping>
