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; 
}

}
