Struts 和 Spring 的整合

web.xml 中完成对 Struts 和 Spring 的整合。在web-app标签中添加代码。

<!-- 让spring随着web项目启动而启动 -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- 读取配置文件 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:applicationContext.xml</param-value>
  </context-param>

struts.xml

struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
	"http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
	<!-- 开启动态方法调用 -->
	<constant name="struts.devMode" value="true"></constant>
	<constant name="struts.enable.DynamicMethodInvocation" value="true"></constant>
	
	<package name="SSH_Forum" namespace="/" extends="struts-default">
		<!-- 允许全部方法 -->
		<global-allowed-methods>regex:.*</global-allowed-methods>
		<action name="UserAction_*" class="com.zsj.web.UserAction">

		</action>
	</package>

</struts>

配置spring

要让spring帮我创建UserService和UserDao，要现在UserAction和UserService中为其创建get和set方法。

<!-- 配置Action -->
	<bean name="userAction" class="com.zsj.web.UserAction" scope="prototype">
		<property name="userService" ref="userService"></property>
	</bean>
	
	<!-- 配置Service -->
	<bean name="userService" class="com.zsj.service.UserService">
		<property name="userService" ref="userDao"></property>
	</bean>
	
	<!-- 配置Dao -->
	<bean name="userDao" class="com.zsjdao.UserDao">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>

告诉struts，不同自己创建Action了，spring帮他创建

回到struts.xml中加上这段代码

<constant name="struts.objectFactory" value="spring"></constant>

这样spring就配置好了。
