本文介绍如何通过Spring框架进行依赖注入，并结合Struts2实现MVC模式的应用开发。详细展示了配置文件的组织方式、数据库连接配置、业务逻辑处理及前端页面展示等内容。

到配置文件部分了，这个是把所有dao，service，action等都分开来写，applicationContext.xml：


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

<!-- 以下为 所有配置action,service,dao 分开写文件引入，也可以在web.xml中引入 -->

	<import resource="actionContext.xml"/>
	<import resource="daoContext.xml"/>
	<import resource="dataAccessContext.xml"/>
	<import resource="serviceContext.xml"/>

</beans>

如果是全部写在一起的话，actionContext.xml,daoContext.xml,dataAccessContext.xml,serviceContext.xml等都不要，则是这样：


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

<!-- 以下为将所有配置action,service,dao集中写在一起的情况  -->

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
		<property name="driverClassName" value="com.mysql.jdbc.Driver" />
		<property name="url" value="jdbc:mysql://localhost:3306/zhiming"/>
		<property name="username" value="root"/>
		<property name="password" value="123456"/>
	</bean>

	<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
		<property name="dataSource">
			<ref local="dataSource"/>
		</property>
		<property name="configLocation">
			<value>WEB-INF/sqlMapConfig.xml</value>
		</property>
	</bean>

	<bean id="userAction" class="com.action.UserAction" scope="prototype">
		<property name="userService" ref="userService" />
	</bean>

	<bean id="userService"
		class="com.service.impl.UserServiceImpl">
		<property name="userDao" ref="userDao"></property>
	</bean>

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

</beans>

applicationContext.xml所import进来的xml文件的文件头那些都要和applicationContext.xml的文件头一样，actionContext.xml部分：


<?xml version="1.0" encoding="UTF-8"?>
<beans default-autowire="byType" 
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

	<!-- Struts2 action类注入 -->
	<bean id="userAction" class="com.action.UserAction" scope="prototype">
		<property name="userService" ref="userService" />
	</bean>

</beans>

daoContext.xml部分：


<?xml version="1.0" encoding="UTF-8"?>

	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
           http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

<!-- IBATIS的DAO的配置注入 -->	
	<bean id="userDao" class="com.dao.impl.UserDao">
		<property name="sqlMapClient" ref="sqlMapClient"/>
	</bean>	

</beans>

           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

	<!-- 读取 jdbc.properties -->

    <!-- 这里的type对应spring配置文件的<beans>元素中的default-autowire属性，若不写则默认  -->
	<constant name="struts.objectFactory.spring.autoWire" value="type" />
	<constant name="struts.objectFactory" value="spring" />

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

dwr.xml配置部分，其作用后面再讲：


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    "http://www.getahead.ltd.uk/dwr/dwr20.dtd">

<dwr>
	<allow>
		<convert match="com.vo.User" converter="bean"></convert>

		<create javascript="jsUser" creator="spring" scope="request">
			<param name="beanName" value="userService"></param>
			<include method="findAllUsers" />
		</create>
	</allow>
</dwr>

最后是jsp页面部分：


<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>
<%@ taglib uri="/struts-tags" prefix="s"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

  <body>
    <table class="table_report">
	<tr> 
		<th>用户ID</th>
		<th>用户名称</th>
		<th>用户性别</th>

    </tr>
    <!-- struts2最正规的取值方式 -->
<%--  <s:iterator id="user" value="%{#session.userList}">--%>
<%--   <s:iterator id="user" value="#session.userList">--%>
   <s:iterator id="user" value="#request.userList">

  </table>
  </body>
