Ajax 请求在 POST 上返回错误请求 (400)

Question

我正在尝试发送这个失败的 ajax 调用。我真的不明白为什么会这样。

有人可以看看我的代码吗？

虽然在 fireBug 中我可以看到有效负载正在正确转换，但调用甚至没有命中控制器代码（在我看来）。

jquery

function userAdd(){
    var array2=new Array();
    var array1=new Array();

    var value2=$('input:checkbox.value2').each(function () {
        if(this.checked){
           array2.push($(this).attr('itemLabel'));
        }
      });

    var value1=$('input:checkbox.value1').each(function () {
        if(this.checked)
        array1.push( $(this).attr('itemLabel'));
      });

    var report = ({
                    user:user,
                    address:$("#address").val(),                
                    regimesRemove:array2,
                    regimesReport:array1

                });


        jQuery.ajax( {
                    async : false,
                    cache : false, 
                    url : "/myapp/user/addUser",
                    type : 'POST',
                    contentType: "application/json; charset=utf-8", 
                    dataType : 'json', 
                    data:JSON.stringify(report),
                    success : function(data) {
                         if(data.errorMessage == undefined){
                            alert(data.errorMessage);
                            window.location.reload();
                        }else if(data.errorMessage !=''){
                            alert(data.errorMessage); 
                            window.location.href="/myapp/user";
                        else 
                            window.location.href="/myapp/user";
                    },
                    complete : function(request, status) {
                     if (status == undefined || status == "error" || status == "parsererror") {

                            alert("Error with status: "+status);
                            window.location.href="/myapp/user/";
                        } else if (status != 'success'){
                            alert("error with status: "+status);
                            alert('error in searching Invalid or submitted records: '+status);
                }
        }
    }); 
}         

Java

 @RequestMapping(value="/addUser",method=RequestMethod.POST)
     public @ResponseBody Report updateRulesForRequest(Model model, HttpServletRequest request,@RequestBody Report report){



     }

确保您用于访问控制器方法的 url 是正确的。 尝试在 ajax 请求中使用更新后的 url 值。

jQuery.ajax( {
                async : false,
                cache : false, 
                url : "${pageContext.request.contextPath }/myapp/user/addUser",
                type : 'POST',
                contentType: "application/json; charset=utf-8", 
                dataType : 'json', 
                data:JSON.stringify(report),
                success : function(data) {
                     if(data.errorMessage == undefined){
                        alert(data.errorMessage);
                        window.location.reload();
                    }else if(data.errorMessage !=''){
                        alert(data.errorMessage); 
                        window.location.href="/myapp/user";
                    else 
                        window.location.href="/myapp/user";
                },
                complete : function(request, status) {
                 if (status == undefined || status == "error" || status == "parsererror") {

                        alert("Error with status: "+status);
                        window.location.href="/myapp/user/";
                    } else if (status != 'success'){
                        alert("error with status: "+status);
                        alert('error in searching Invalid or submitted records: '+status);
            }
    }
