ajax-AJAX發送請求，後台接受到數據但是返回結果後，Ajax請求結果失敗

AJAX發送請求，後台接受到數據但是返回結果後，Ajax請求結果失敗

前台JS和後台相應如下：

 var username = $("#user_name").val().trim();
    var password = $("#password").val();
    console.log(username+","+password);
    $.ajax({
        url:"/Test1224/login.action",
        data:{"username":username,"password":password},
        dataType:"json",
        type:"POST",
        success:function(result){
            console.log("success");
            console.log(result);
        }
    });

 protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        // TODO Auto-generated method stub
        super.doPost(req, resp);
        System.out.println("enter doPost");
        resp.setCharacterEncoding("UTF-8");
        resp.setContentType("text/html;charset=UTF-8");
        System.out.println(req.getParameter("username")+","+req.getParameter("password"));
        PrintWriter pw = resp.getWriter();
        Result result = new Result();
        result.setFlag(true);
        result.setName(req.getParameter("username"));
        pw.print(result);
        pw.close();
    }

錯誤提示：POST http://127.0.0.1:9080/Test1224/login.action 405 (Method Not Allowed)

最佳回答：

問題已解決，將super.doPost(req, resp);刪除掉就好了。進入super.dopost(）一下就明白了
