上面内容是我遇到问题，报出的错误提示。

先说一下出现这个问题的背景环境吧!

ssh2  不用说，主要是前段显示，我用的EasyUI库，用过或听过这个js库的人，大概都晓得他的数据传输是通过ajax来交互的，数据格式都是json，反正此时我是用的json（接触的时间比较短），

谢了一个action,如下:

@Action("menuAction")public class MenuAction extends BaseAction implements ModelDriven<Menu> {private Menu menu = new Menu();@Overridepublic Menu getModel() {return menu;}@Autowiredprivate MenuServiceI menuService;public String getAllMenuNode() {List<Menu> list = menuService.getAllMenuNode();if(list != null && list.size()>0) {super.writeJson(list);}return "success";}}

可是在页面js中，通过ajax来调用这个action的getAllMenuNode() 方法的时候，数据正常显示了，都没问题，开始我认为搞定，突然一看后台，我靠，好多错误，报错了。后来找了好多方法，最终发现原来我编写的getAllMenuNode(), 是严格按照struts2的action的规范写的，必须要有返回值，并且为String，可是在此处，我用的easyui技术，通过ajax技术传输数据，所以没有就没有按照以前的写法那样，成功了 跳到那个页面：就像下面这样：

<action name="menuAction" class="menuAction" method="getAllMenuNode">
<result name="success">/kkk.jsp</result>
</action>

而我用ajax，没必要通过返回string 来标识跳转到那个页面，但是又按照规范谢了返回的String，但是我又没有编写跳转到那个页面，所以struts的这个action接到请求，并且

getAllMenuNode()执行完毕，并且返回个String 类型的success值，那么struts当然会按照他的规范去找与之匹配的result跳转页面，可是我又没有给他编写，所以他就会找不到当然会报错Could not find action or result。而ajax调用，数据返回通过response.write写回到页面，所以数据显示没有问题。

最后我把getAllMenuNode()  按照如下修改：去掉了返回值

public void getAllMenuNode() {
List<Menu> list = menuService.getAllMenuNode();
if(list != null && list.size()>0) {
super.writeJson(list);
}
}


问题结局了！！！
