使用ajax发起post 请求

 $.ajax({
                    url: "/enroll/visit/StuInformation",
                    type: "POST",
                    dataType: "json",
                    data: {
                        "username": $.trim($("#subUsername").val()),
                        "stuNickname": $.trim($("#subNickname").val()),
                        "schoolName": $.trim($("#school-name").val()),
                        "stuClass": $.trim($("#subClass").val()),
                        "telephone": telephone,  //手机号;
                        "stuNumber": $.trim($("#stuNumber").val()),  //学号
                        "stuQQ": $.trim($("#stuQQ").val()),
                        "email": $.trim($("#subEmail").val()),
                        "verificationCode": $.trim($("#checking").val()),
                        "vaptcha_server": $.trim($("input[name='vaptcha_server']").val()),
                        "vaptcha_token": $.trim($("input[name='vaptcha_token']").val()),
                        "printFlag": options.val()
                    },
                    timeout: 5000,


                    success: function (data) {
                        if (data.code == 'OK'){
                            //跳转到下载须知;
                            alert("提交成功");
                            window.location.href = "/enroll/page/portal/index.html"
                        } else {
                            alert(data.message);
                        }
                    },

                    complete: function (XMLHttpRequest, status) { //请求完成后最终执行参数
                        if (status == 'timeout') {//超时,status还有success,error等值的情况
                            ajaxRequest.abort();
                            alert("服务器超时")
                        }
                    }
                })

接收;

  @PostMapping(value = "/visit/StuInformation")
    public commonData conserveInformation(formData param , HttpServletRequest request){

        HttpSession session=request.getSession();
        //验证数据;
        //判断是否重复提交;
        //获取ip
        param.setIp(request.getRemoteAddr());
        System.out.println(param.getIp());
        //获取cookie
        param.setCookie(request.getHeader("Cookie"));

        //获取请求头
        param.setRequestHead(request.getMethod()+"\n"+request.getHeader("Host")+
                "\n"+request.getHeader("Accept-Encoding")+"\n"+request.getHeader("Accept-Language")
                +"\n"+request.getHeader("Cookie")+"\n"+request.getHeader("Referer")+"\n"+request.getHeader("User-Agent")
                 );

        boolean flag=enrollservice.checkData(param, (String) session.getAttribute("verificationCode"));

        commonData  commondata=new commonData();

        if(!flag){
            commondata.setMessage("数据验证未通过请注意查看所填写信息");
            commondata.setCode(statusCode.FOUND);
            commondata.setSuccess("success");
            return  commondata;
        }

         boolean identify= enrollservice.saveRegistrationInformation(param);

        if(identify) {
            //注册成功后立即取消验证码;
            session.removeAttribute("verificationCode");
            commondata.setSuccess("success");
            commondata.setMessage("报名成功!!!");
            commondata.setCode(statusCode.OK);
        }else {
            commondata.setSuccess("success");
            commondata.setSuccess("内部错误请稍后再试");
            commondata.setCode(statusCode.FOUND);
        }


        return commondata;
    }

请问有知道这是为啥的吗？,能帮忙解释一下吗？

302到了500页面，你的代码没有相关重定向操作，说明可能发生了未捕获异常，mvc异常处理逻辑执行了重定向。你看看302那台tomcat的日志应该有错误日志
