java spring rest参数不起作用

Question

我创建了将数据传递给spring rest的代码，但这些代码不能正常工作请参见下面的代码：

@PutMapping("/notification/save/{id}")
public @ResponseBody String update(@PathVariable("id") long id, @RequestBody  AccountNotification accountNotification){
    String result="ok";
    ServiceAccount serviceAccount =  new ServiceAccount();
    serviceAccount.setId(id);
    //accountNotification.setServiceAccount( serviceAccount );
    //result =notificationsService.update(id,accountNotification);

    JSONObject jObject = new JSONObject();
    try
    {
        JSONArray jArray = new JSONArray();
             JSONObject accountNotificationJSON = new JSONObject();

             if(result.equals("ok")) {
                 accountNotificationJSON.put("success", "true");
                 accountNotificationJSON.put("messages", "Successfully Saved");
             }
             else {
                 accountNotificationJSON.put("success", "false");
                 accountNotificationJSON.put("messages", "NOT Successfully Saved");

             }
             jArray.put(accountNotificationJSON);

        jObject.put("data", jArray);
    } catch (JSONException jse) {
        logger.error( jse.getMessage());
    }


    return jObject.toString();
}

我的javascrit有：

$("#saveChanges").on('click',function(){
     var params1={
             proxy:$(proxy).val() ,
             port:$(port).val(),
             uri:$(uri).val(),
             actived:$(actived).val()=="on"?true:false
     };

     $.ajax({
         url: 'notification/save/'+id,
         params: params1,
         type: 'post',
         success:function(response) {
             if(response.data[0].success == "true") {                      
                 $(".removeMessages").html('<div class="alert alert-success alert-dismissible" role="alert">'+
                      '<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>'+
                      '<strong> <span class="glyphicon glyphicon-ok-sign"></span> </strong>'+response.data[0].messages+
                     '</div>');


                 // close the modal
                 $("#editMember").modal('hide');

             } else {
                 $(".removeMessages").html('<div class="alert alert-warning alert-dismissible" role="alert">'+
                      '<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>'+
                      '<strong> <span class="glyphicon glyphicon-exclamation-sign"></span> </strong>'+response.data[0].messages+
                     '</div>');
             }
         },
         error: function(x, e) {
                alert(x);
              }

     });

在您的Rest代码中有一个put映射@putmapping（“/notification/save/{id}”），但是在post方法调用的js中类型:'post',so它返回400bad request，您应该使用type:put，它等于您的Rest方法。

 @PutMapping("/notification/save/{id}")
 public @ResponseBody String update(@PathVariable("id") long id, 
 @RequestParam  AccountNotification accountNotification){
 .....
 }



  $.ajax({
     url: 'notification/save/'+id,
     params: params1,
     type: 'put',
     success:function(){
 }})
