这有点令人困惑，但这是我的项目要求。我正在使用spring
mvc和jquery。现在，我必须发布表单，并使用jquery的ajax调用将数据公开到后端，因为我的jquery是

home='<%=request.getContextPath()%>';

$('#userReg').submit(function(event){
    var add = {}
    add["type"] = $("#type").val();
    add["name"] = $("#companyName").val();
    add["regNumber"] = $("#regNumber").val();
    add["dob"] = $("#dob").val();
    add["email"] = $("#email").val();
    add["password"] = $("#password").val();
    add["confirmPassword"] = $("#cpassword").val();
    add["line1"] = $("#line1").val();
    add["line2"] = $("#line2").val();
    add["state"] = $("#state").val();
    add["country"] = $("#country").val();
    add["zipCode"] = $("#zipCode").val();
    console.log("search: ", add);
    event.preventDefault();
    $.ajax({
        type : "POST",
         headers: { 
                'Accept': 'application/json',
                'Content-Type': 'application/json' 
            },
            url : home+"/addCompany",
        data : JSON.stringify(add),
        dataType : 'json',
        timeout : 100000,
        success : function(data) {
            console.log("SUCCESS: ", data);
            alert(data)

        },
        error : function(e) {
            console.log("ERROR: ", e);
            alert(e);

        },done : function(e) {
            console.log("DONE");
        }
});
});

和相应的方法

 @RequestMapping(value="/addCompany",method=RequestMethod.POST,consumes=MediaType.APPLICATION_JSON_VALUE)
   public@ResponseBody String userLogin(HttpServletRequest req,@RequestBody CompanyRegVO user){
    logger.debug("signUp user:"+user);
     // get reCAPTCHA request param
    String gRecaptchaResponse = req.getParameter("g-recaptcha-response");
    boolean isVerified= Verify.verifyGcaptchResponse(gRecaptchaResponse);
    ObjectMapper mapper=new ObjectMapper();
    String jsonString="";       
    System.out.println("signUp user:"+user);
    Integer id=null;
    try{
        if(isVerified){
            id = signupHandler.process(user);
            if(id!=null){
                logger.debug("ID in controller:"+id);

                emailHandler.sendVerificationMail(id,user.getEmail());
                System.out.println("user create successfully");

            }
            jsonString=mapper.writeValueAsString("User creaated successfully");

        }
         else
        jsonString= mapper.writeValueAsString("please verify that you are not a robot");
    } catch (JsonGenerationException e) {

        e.printStackTrace();
    } catch (JsonMappingException e) {

        e.printStackTrace();
    } catch (IOException e) {
                e.printStackTrace();
    } catch (Exception e) {
        try {
            jsonString=mapper.writeValueAsString(e.getMessage());
        } catch (JsonProcessingException e1) {

        }
        return jsonString;
    }


    return "success";

   }

现在，我的表单已与此URL映射

@RequestMapping(value="/signUp",method=RequestMethod.GET)
   public String register(Model model){
    CompanyRegVO user=new CompanyRegVO();
    model.addAttribute("userForm", user);
    return "signUp";
   }

当我提交表单时，我希望我的jquery代码将执行，将调用我的上一个方法，但它会调用get方法上方，并以我的数据作为查询参数返回signUp页面。现在，如果我评论“
/ signUp”的映射，我的服务器将显示404错误。因为页面已映射到该URL。那么任何人都可以告诉我这种情况jquery或spring的补救方法是什么？
