       <servlet-mapping>改了下，还是没用哈

    你的是

     @RequestMapping(name="out")

    我的

    @RequestMapping(value="/user/index.do")

    ==！，可以，谢谢了！ @RequestMapping(name="out")这里应该是 @RequestMapping(｛"out"｝)吧谢谢，已经解决了@RequestMapping(value="")用value属性回复 @nww57:麻烦结贴恩，谢谢，已经解决了

    引用来自“YouKnowNothing”的评论

    @RequestMapping(value="")用value属性
