我让你们做一个简单新闻程序,只要两个功能就可以了
1.新增新闻,
2.新闻能生成html

------解决方案--------------------

Java code


采用Servlet即可：
先应该有一个index.html

//IndexServlet.java
package com.yuce.servletapp;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class IndexServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        PrintWriter out = resp.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">");
        out.println("<title>Insert title here</title>");
        out.println("</head>");
        out.println("<body>");
        if(getServletConfig().getInitParameter("newNewpath")!= null
                && getServletConfig().getInitParameter("newNewName")!= null){
            out.println("<a href=" + getServletConfig().getInitParameter("newNewpath")+">");
            out.println(getServletConfig().getInitParameter("newNewName"));
            out.println("<a>");
        }
        out.println("</body>");
        out.println("</html>");
        out.flush();
    }

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

//newReportServlet.java
package com.yuce.servletapp;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class newReportServlet extends HttpServlet {
    private FileReader fr;
    private BufferedReader br;
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        fr = new FileReader(getServletConfig().getInitParameter("filename"));
        br = new BufferedReader(fr);
        PrintWriter out = resp.getWriter();
        out.println("<html>");
        out.println("<head>");
        out.println("<meta http-equiv=\"Content-Type\""+ 
                                          "content=\"text/html; charset=UTF-8\">");
        out.println("<title>Insert title here</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h4 align=\"center\"> " +
                getServletConfig().getInitParameter("title") + "</h4>");
        out.println("<hr>");
        String s = null;
        StringBuffer sb = new StringBuffer();
        while((s = br.readLine())!= null){
            sb.append(s);
            sb.append("\n");
            
        }
        out.println("<pre>" + sb.toString() + "</pre>");
        out.printl
