lizhe.jsp的代码
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<body>
<form action="TextServle" method="post">
姓名：<input type="text" name="username">
<input type="submit" value="提交">
</form>
</body>
</html>

TextServle的代码
package com.lizhe;

import java.io.IOException;

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

import com.li.UserManager;

public class TextServle {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
UserManager lo = new UserManager();
lo.add(username);
request.getRequestDispatcher("/add_success.jsp").forward(request, response);;
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
}

web.xml
的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>TextServle</servlet-name>
<servlet-class>com.lizhe.TextServle</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TextServle</servlet-name>
<url-pattern>/TextServle</url-pattern>
</servlet-mapping>
</web-app>

输入http://localhost:8080/text0/lizhe.jsp 正常显示lizhe.jsp页面输入名字来到http://localhost:8080/text0/TextServle
