Javascript SpringMVC中Ajax请求的404实现

我正在尝试制作一个简单的登录表单。在这个例子中，我使用Spring MVC，为APIResponseModel创建了一个简单的类（这个类包含三个变量，有getter和setter，分别是Status、Message和HTTPStatus），当我填写凭证并单击submit时，我得到的ajax响应是404，但当我在控制器中选中同一个时，它返回

{“Status”：“200”，“message:“Login Success！！”，“data”：Admin}

同样，我在Ajax响应中获得404作为状态。如果您能帮助我，请在这里附上代码，并让我知道我在这里做错了什么

弹簧控制器

@RequestMapping("/login")
    public APIResponseModel getLoginPage(@ModelAttribute("loginUser")UserDTO userDto, HttpSession session) {
        APIResponseModel apiResponseModel = new Utils().getDefaultApiResponse();
        logger.info("USER DTO :" + userDto.toString());
        List<String> errorList = new ArrayList<>();
        try {
            userService = new UserServiceImpl();
            UserModel userModel = userService.validateLogin(userDto,null, errorList);
            if(errorList.isEmpty()) {
                apiResponseModel.setMessage("Login Success!!");
                apiResponseModel.setStatus(HttpStatus.OK);
                if(userModel.getRole() == Constants.UserRole.ADMIN) {
                    apiResponseModel.setData("Admin");
                }else if(userModel.getRole() == Constants.UserRole.STORE_MANAGER) {
                    apiResponseModel.setData("StoreOwner");
                }else {
                    apiResponseModel.setData("landing");
                }
                session.setAttribute("loggedInUser", userModel);
            }else {
                apiResponseModel.setMessage(errorList.isEmpty() ? "Invalid Credientials !!" : errorList.toString());
            }
            
        }catch(Exception exe) {
            exe.printStackTrace();
            logger.info("Exception occured at : " + exe.getMessage());
        }
        logger.info("------------------------------------------------------------------------");
        logger.info(apiResponseModel);
        return apiResponseModel;
    }

MasterAjax类

        this.processData = null;
        this.contentType = null;
        this.responseData = null;
        this.responseStatus = null;
        this.responseStatusCode = null;
    }
    
    requestData(callBack){
        
        var parameterError=false;
        if(null == this.requestType){
            parameterError=true;
            console.log("Error: Request Type can't be null");
        }    
        if(null === this.url || undefined === this.url || "undefined" === this.url){

            console.log("Error: URL can't be null");
        }  
        if(null == this.data || this.data.length <= 0){
            //console.log("Warning: Data is null");
        }
        if(parameterError === false){
            /*toggleSpinnerOn();  */
            $.ajax({
                type : this.requestType,
                enctype : this.enctype,
                processData : this.processData, 
                contentType : this.contentType, 
                url : global_contextPath+"/"+this.url,
                data: this.data,

                success : function(responseData,textStatus) {
                    /*toggleSpinnerOff();*/
                    callBack(responseData,textStatus);
                },
                error : function(responseData,textStatus) {

                    callBack(responseData,textStatus); 
                }
            }); 
        }
        //return this.responseData;
    }
    
}

class MasterAjax{
构造函数（）{
this.requestType=null；
this.url=null；
这个超时=100000；
this.enctype=null；
this.data=null；
this.processData=null；
this.contentType=null；
this.responseData=null；
this.responseStatus=null；
this.responseStatusCode=null；
}
请求数据（回调）{
var参数error=false；
if（null==this.requestType）{
参数error=true；
log（“错误：请求类型不能为null”）；
}    
if（null==this.url | | undefined===this.url | |“undefined”==this.url）{
参数error=true；
log（“错误：URL不能为空”）；
}  
如果（null==this.data | | this.data.lengthMissed
@ResponseBody
要在控制器上添加，这就是为什么它不在调用时发送响应

class MasterAjax{
    constructor(){
        this.requestType = null;
        this.url = null;
        this.timeout = 100000;
        this.enctype =  null;
        this.data = null;
        this.processData = null;
        this.contentType = null;
        this.responseData = null;
        this.responseStatus = null;
        this.responseStatusCode = null;
    }
    
    requestData(callBack){
        
        var parameterError=false;
        if(null == this.requestType){
            parameterError=true;
            console.log("Error: Request Type can't be null");
        }    
        if(null === this.url || undefined === this.url || "undefined" === this.url){
            parameterError=true;

        }

            //console.log("Warning: Data is null");
        }
