spring mvc 400 Required String parameter 'quizId' is not present 前端参数找不到

Question

如下图所展示， 前端发起一个异步请求，传递了一个json对象

$scope.addQuestionToTest = function(qid){
         var sendData={"quizId":$scope.tid,"questionId":qid};
         $http({
                url: WEBROOT+"/test/addquestion",
                method: 'POST',
                headers: {
                    "Authorization": Data.token()
                },
                data: sendData
            }).success(function (data) {...

 
firebug中的前端数据如下

头信息

 
 
以下服务端的代码

    @RequestMapping(value = "/addquestion",method=RequestMethod.POST)  
    @ResponseBody  
    public ResponseBase addQuestion(  
            @RequestParam(value="quizId", required=true)   String quizId,  
            @RequestParam(value="questionId", required=true)   Integer questionId  
            ) {  

 
spring mvc中报错400, debug跟到spring web的DispatchServlet，发现抛出的具体异常是请求的quizId找不到

    org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'quizId' is not present  

 

奇了个怪了，为什么会找不到前端的参数，明明再firebug中都有的，请各位指教

 

Answer 1

[code="java"]@RequestMapping(value = "/addquestion",method=RequestMethod.POST)

@ResponseBody

public ResponseBase addQuestion(

@RequestBody Map params

) {

String quizId = params.get("quizId").toString();
Integer questionId = Integer.parseInt(params.get("questionId").toString());
}[/code]

试试这么写
