新闻系统-详细信息

页面效果:

1、前端：showdetail.jsp

<%@page import="Service.ArticleBiz"%>

<%@page import="POJO.Article"%>

<%@page import="com.sun.xml.internal.bind.v2.schemagen.xmlschema.Import"%>

<%@page language = "java" import = "java.util.*" pageEncoding = "utf-8"%>

String path = request.getContextPath();

String basePath = request.getScheme() + "://" + request.getServerName()+":"+

request.getServerPort() + path +"/";

<% Article article = (Article)request.getAttribute("article"); %>

<!DOCTYPE html>

<html>

<head>

<title>Insert title here</title>

</head>

<body>

修改新闻<br>

<input type = "hidden" name = "id" value = "<%= article.getId()%>"/>标题

<%= article.getTitle()%><br>作者

<%= article.getAuthor()%><br>内容

<%= article.getContent() %><br>

<a href = "ArticleShowList">返回新闻列表</a>

</body>

</html>

2、控制层(Controller)代码

ArticleShow .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("/ArticleShow")

public class ArticleShow extends HttpServlet {

@Override

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

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

ArticleBiz articleBiz =new ArticleBiz();

Article article = articleBiz.get(id);

request.setAttribute("article", article);

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

}
