$.ajax請求報400 bad request錯誤

頁面請求程式碼:

$.ajax({
            url:"check/checkUser.do",
            type:"post",
            data:{"mobile=":mobile },
            dataType:"json",
            contentType:"application/json",
            success:function(){
               
            },
           
        });

Controller類UserCheckController 程式碼如下:

@Controller
 
public classUserCheckController {
@RequestMapping("/check/checkUser.do")
publicModelAndView checkUser(@RequestParam("mobile") Stringmobile){
    ModelAndView modelAndView = newModelAndView("/login/login");
    System.out.println("1");
    return modelAndView;
}


錯誤原因:是因為類UserCheckController的請求處理方法checkUser的引數錯誤

@RequestParam("mobile")String mobile

改為HttpServletRequestrequest,HttpServletResponse response

網上還有很多別的錯誤型別,我就不列舉了。
