页面效果:

1、前端：addnews.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html>

<%int id = Integer.parseInt(request.getParameter("id")); %>

<html>

<head>

<title>Insert title here</title>

</head>

<body>

确认删除<br>

</form>

</body>

</html>

2、控制层(Controller)代码

ArticleDelete.java

package Controller;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import POJO.Article;

import Service.ArticleBiz;

@WebServlet("/ArticleDelete")

public class ArticleDelete extends HttpServlet {

@Override

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

int id = Integer.parseInt(request.getParameter("id"));

ArticleBiz articleBiz =new ArticleBiz();

articleBiz.delete(id);

request.getRequestDispatcher("index.jsp").forward(request, response);

}
