struts2 与 spring 整合

此文章的例子承接上一篇与velocity整合的例子：

 

首先看下需要依赖的类库：

<dependencies>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>3.8.1</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-core</artifactId>
			<version>2.1.8</version>
			<scope>compile</scope>
		</dependency>
		<dependency>
			<groupId>xstream</groupId>
			<artifactId>xstream</artifactId>
			<version>1.2</version>
			<scope>compile</scope>
		</dependency>
		<dependency>
			<groupId>oro</groupId>
			<artifactId>oro</artifactId>
			<version>2.0.8</version>
			<scope>complie</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.velocity</groupId>
			<artifactId>velocity</artifactId>
			<version>1.6</version>
			<scope>compile</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.velocity</groupId>
			<artifactId>velocity-tools</artifactId>
			<version>1.3</version>
			<scope>compile</scope>
		</dependency>
		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts2-spring-plugin</artifactId>
			<version>2.1.8.1</version>
			<scope>compile</scope>
		</dependency>
	</dependencies>

 

以上都是需要用到的。然后

1，修改 web.xml 添加ContextLoaderListener，对上下问的生命周期发生变化进行监听。如果不清楚监听器需要复习下这部分内容。

	
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

 

2，增加/WEB-INF/applicationContext.xml

<?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="helloWorldClass" class="com.yajun.helloworld.HelloWorld">
		<property name="userName" value="Hello World!" />
	</bean>
</beans>

 里面可以配置类

3，修改struts

<package name="default" extends="struts-default">
		<action name="HelloWorld" class="helloWorldClass">
			<result name="SUCCESS">/success.vm</result>
		</action>
	</package>

 然后运行就可以看见效果了。
