Struts与Spring集成方式

struts1.x版本和spring的集成与struts2.0和spring的集成存在较大的差异

 

struts1.x与spring集成方式

 

方式一：Action交给spring管理,将业务类注入action

          引入spring-webmvc-struts.jar包到lib下，

 

          struts配置：

          <action path="/searchAction"  type="org.springframework.web.struts.DelegatingActionProxy" parameter="method">

               <forward name="success" path="/result.jsp"/>

          </action>

 

           spring配置：

           <!--这里SearchAction继承了DelegatingActionProxy-->

           <bean name="/searchAction" class="com.myproject.action.SearchAction" scope="prototype">

                    <property name="searchService" ref="searchService"/>

           </bean>

           注意：保持spring配置的bean name和struts配置的action path一致

 

 方式二：请求首先交给ActionServlet，然后给org.springframework.web.struts.DelegatingRequestProcessor，由这个请求处理器根据请求路径从spring容器获取action对象

 

         struts-config.xml

          <action path="/searchAction">            <!--注意到没有？这里没有配置type属性-->

                   <forward name="success" path="/result.jsp"/>

          </action>

        

          <controller>

               <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>

          </controller>

 

        spring配置：

         <bean name="/searchAction" class="com.myproject.action.SearchAction" scope="prototype">

                    <property name="searchService" ref="searchService"/>

         </bean>

        

方式三：Action不交给spring管理，直接在Action中实例化应用上下文，然后通过getBean("xxx")，获取相应业务对象

          struts配置遵照传统方式

          <action path="/searchAction"  type="com.myproject.action.SearchAction">

               <forward name="success" path="/result.jsp"/>

          </action>

         

       

          private ApplicationContext context=WebApplicationContextUtils.getWebApplicationContext(this.getServlet().getServletContext());

         

          SearchService searchService=(SearchService)context.getBean("searchService");

 

 

 

struts2.x与spring集成

 

     struts.properties 配置

           struts.objectFactory=spring            #指定struts的action类实例由spring生成

 

     struts-config.xml配置

           <action name="search" class="searchAction" method="searchMax">

                  <result name="success">/result.jsp</result>

                  <result name="error">/error.jsp</result>

           </action>

 

     spring配置

            <bean id="searchAction" class="com.myproject.action.SearchAction" scope="prototype">

                    <property name="searchService" ref="searchService"/>

           </bean>

 

   以上标红的两处须保持一致。
