servletfirst.java

这是我老师自己做的程序代码,挺不错的,要的话可以来下载

package example;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;


public class ServletFirst extends HttpServlet {
    private static final String CONTENT_TYPE = "text/html; charset=GBK";

    //Initialize global variables
    public void init() throws ServletException {
    }

    //Process the HTTP Get request
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {

        response.setContentType(CONTENT_TYPE);   //响应的格式
        response.setCharacterEncoding("GB2312") ;//响应的字符编码（汉字）
        PrintWriter out = response.getWriter();  //生成一个PrintWriter对象

        String un =  request.getParameter("username") ;//获得文本框内的字符串
        out.println("<b>" + un + "</b>欢迎你使用servlet<br/>");

        out.close();

    }

    //Process the HTTP Post request
    public void doPost(HttpServletRequest request, HttpServletResponse response) throws
            ServletException, IOException {
        doGet(request, response);
    }

    //Clean up resources
    public void destroy() {
    }
}
