请问这是什么错误

spring 的配置文件 ***.xml中配置有问题

1可能是springmvc配置文件中没有配注解驱动mvc:annotation-driven/。
2如果你在做发送ajax请求，它默认类型为'application/x-www-form-urlencoded;charset=UTF-8'的话，就会出问题了，因为Spring MVC使用的是‘application/json’，所以需要在ajax请求中改成'Content-Type' : 'application/json;charset=utf-8'，如下代码headers块：

require([ "dojo/request/xhr", "dojo/json" ], function(xhr) {  
            var userInfo = {  
                "userName" : user.value,  
                "password" : passwd.value  
            };  
            xhr.post("/SpringMVCRestful/login", {  
                data : JSON.stringify(userInfo),  
                //query: JSON.stringify(userInfo), //加这个会在url显示参数  
                sync : true,  
                handleAs : "json",  
                timeout : 200000,  
                **headers : {  
                    'Content-Type' : 'application/json;charset=utf-8'  
                }** 
            }).then(function(response) {  
                alert(response);  
            }, function(err) {  
                alert("err:" + err);  
            });  
        });
