Spring Struts2 整合

整合什么？——用IoC容器管理Struts2的Action

如何整合？
第一步：配置Struts2
1.加入Struts2的jar包。
2.配置web.xml文件。
3.加入Struts2的配置文件struts.xml

第二步：配置Spring
1.加入Spring的jar包
Spring的标准 jar包。
另外还有struts-spring-plugin-plugin-2.3.31.jar包

2.添加Spring的配置文件——beans.xml

3.在Spring的IoC容器中配置Struts2的Action——注意配置中需要把Action配置成非单例模式scope=prototype.

<beans id="infoAction" class="com.itnba.maya.controller.InfoAction" scope="prototype">
    <property name="infoService" ref="com.itnba.maya.services.InfoService"></property>
</beans>

4.配置struts.xml。把<action>的class属性指向IoC容器相应bean的id。

<action name="*_*" class="infoAction" method="{2}">
    <result>
        {1}/{2}.jsp
    </result>
</action>

5.在Web.xml中添加配置

<!--配置Spring配置文件的名称和位置-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:beans.xml</param-value>
</context-param>
<!--启动IoC容器的监听器-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

web.xml配置的作用：
1)创建IoC容器的对象。
2)把对象放到Application中。
