Caused by: java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'xxx' method

困扰了2天的一个问题，一般遇到这个异常是因为同一个控制器controller里面有两个requestmapping的映射路径重复了导致的，我遇到这个问题是因为自己的大意导致的：

错误 例子：

@RestController
public class WeiXinController extends BaseController {

    @RequestMapping(name = "wocaonima", method = RequestMethod.GET)
    public String wocaonima() {
        return "hello demo";
    }


    @RequestMapping(name = "nidayea", method = RequestMethod.GET)
    public void  nidayea () {
        System.out.println("hello nidayea");
        //return "hello nidayea";
    }

}

如果不认真看的话，感觉一点问题都没有，但是认真一看的话，发现是因为把value 写成了 name导致的

正确例子：

@RestController
public class WeiXinController extends BaseController {

    @RequestMapping(value = "wocaonima", method = RequestMethod.GET)
    public String wocaonima() {
        return "hello demo";
    }


    @RequestMapping(value = "nidayea", method = RequestMethod.GET)
    public void  nidayea () {
        System.out.println("hello nidayea");
        //return "hello nidayea";
    }

}
