1.编写servlet: TreeDataServlet.java
[java] view plaincopyprint?
- package com.maggie.tree;
-
- import java.io.IOException;
-
- import javax.servlet.ServletException;
- import javax.servlet.http.HttpServlet;
- import javax.servlet.http.HttpServletRequest;
- import javax.servlet.http.HttpServletResponse;
-
- public class TreeDataServlet extends HttpServlet{
-
- private String getData(){
- StringBuffer sb = new StringBuffer();
- sb.append("Hello~First Servlet!");
- return sb.toString();
- }
-
- @Override
- protected void doGet(HttpServletRequest req, HttpServletResponse resp)
- throws ServletException, IOException {
- // TODO Auto-generated method stub
- // super.doGet(req, resp);
- String data = this.getData();
- resp.setContentType("text/html;charset=GBK");
- resp.getOutputStream().write(data.getBytes("GBK"));
- }
-
- @Override
- protected void doPost(HttpServletRequest req, HttpServletResponse resp)
- throws ServletException, IOException {
- // TODO Auto-generated method stub
- // super.doPost(req, resp);
- }
- }
2.配置web.xml
[xhtml] view plaincopyprint?
- <?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">
- <servlet>
- <servlet-name>treeServlet</servlet-name>
- <servlet-class>
- com.maggie.tree.TreeDataServlet
- </servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>treeServlet</servlet-name>
- <url-pattern>/treeServlet</url-pattern>
- </servlet-mapping>
- </web-app>
3.测试,访问地址:http://localhost:8080/fistServlet/treeServlet
