struts与spring三种整合方法

struts与spring三种整合方法

<!-- 载入applicationContext上下文-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/*applicationContext*.xml</param-value>
</context-param>

第一种:使用 Spring 的 ActionSupport 类整合 Structs

继承spring的ActionSupport类

public class ShowDeptListAction extends ActionSupport {

public ActionForward execute(ActionMapping mapping, ActionForm form,
       HttpServletRequest request, HttpServletResponse response) {

      DeptManager deptManager = (DeptManager) getWebApplicationContext()
        .getBean("deptManager");
      List<Dept> list = deptManager.getAllDept();
      request.setAttribute("list", list);
      return mapping.findForward("ok");

}

}


第二种:使用 Spring 的 DelegatingRequestProcessor 覆盖 Struts 的 RequestProcessor

在struts-config.xml 文件加入：

<controller     processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />

在spring上下文配置文件中作为bean注册：

<beans>
<bean name="/showDeptList"
     class="cn.com.thinkbank.struts.action.ShowDeptListAction">
     <property name="deptManager" ref="deptManager" >
     </property>
</bean>
</beans>

servlet代码类如下：

public class ShowDeptListAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,
      HttpServletRequest request, HttpServletResponse response) {

     List<Dept> list = deptManager.getAllDept();
     request.setAttribute("list", list);
     return mapping.findForward("ok");

}

private DeptManager deptManager;

public void setDeptManager(DeptManager deptManager) {
     this.deptManager = deptManager;
}

}

第三种:将 Struts Action 管理委托给 Spring 框架
在struts-config.xml 文件加入：

<action-mappings>
     <action path="/showDeptList"
   type="org.springframework.web.struts.DelegatingActionProxy">
      <forward name="ok" path="/form/showDeptList.jsp"></forward>
     </action>
</action-mappings>

在spring上下文配置文件中作为bean注册：

<bean name="/showDeptList"
     class="cn.com.thinkbank.struts.action.ShowDeptListAction">
     <property name="deptManager" ref="deptManager" >
     </property>
</bean>

servlet代码类如下：

public class ShowDeptListAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,
      HttpServletRequest request, HttpServletResponse response) {

     List<Dept> list = deptManager.getAllDept();
     request.setAttribute("list", list);
     return mapping.findForward("ok");

}

private DeptManager deptManager;

public void setDeptManager(DeptManager deptManager) {
     this.deptManager = deptManager;
}

}
