无法访问错误提示 HTTP Status 405 ? ????? 如何解决？

Java类代码如下、

package com.servlet;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;



public class PryingHtml extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doGet(req, resp);

        //通过响应的回传流回html数据页面
        resp.setContentType("text/html; charset=UTF-8");

        PrintWriter writer = resp.getWriter();
        writer.write(" <!DOCTYPE html>\r\n");
        writer.write(" <html lang=\"en\">\r\n");
        writer.write(" <<head>\r\n");
        writer.write("  <meta charset=\"UTF-8\">\r\n");
        writer.write(" <title>Title</title>\r\n");
        writer.write(" </head>\r\n");
        writer.write(" <body>\r\n");
        writer.write(" <!DOCTYPE html>\r\n");
        writer.write(" <body>\r\n");
        writer.write("  这是html页面....\r\n");
        writer.write(" <body>\r\n");
        writer.write("</html>\r\n");


    }
}

web.xml代码如下。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">


    <servlet>
        <servlet-name>PryingHtml</servlet-name>
        <servlet-class>com.servlet.PryingHtml</servlet-class>

    </servlet>

    <servlet-mapping>
        <servlet-name>PryingHtml</servlet-name>
        <url-pattern>/PryingHtml</url-pattern>
    </servlet-mapping>

</web-app>

把super.doGet和super.doPost这两个删除

估计是你提交是post 方法，里面只有get 方法，添加一个post 方法就可以了
