spring struts整合策略

1。装载Spring context
2。整合Struts

1。装载Spring context 的方法主要有两种：

（1）在struts-config.xml中配置

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

<set-property peperpty="contextConfigLocation" value="/WEB-INF/classes/applicationContext.xml"/>

</plug-in>

（2）在web.xml中配置

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>

<servlet>
<servlet-name>context</servlet-name>
<servlet-class>
org.springframework.web.context.ContextLoaderServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>


2。整合Struts方法主要有3种:
(1)用户Action直接继承ActionSupport类，调用getWebApplicationContext().getBean()方法注入所需要的类.

(2)使用Spring的DelegationRequestProcessor代替ActionServlet.
<!-- 将struts交由spring管理 -->
<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor">
</controller>
(3)使用Spring的委托代理.
