使用GenericServlet实例
package com.kettas.servlet;
import javax.servlet.* ;
import java.io.* ;
public class GenDateServlet extends GenericServlet{
@Override
public void service( ServletRequest request , ServletResponse response )
throws ServletException ,IOException
{ response.setContentType( "text/html" ) ; // 设置响应内容类型
PrintWriter out = response.getWriter();// 获得文本写入流
// 给客户端回应的html文本
out.println( "<html>" ) ;
out.println( "<body>" ) ;
out.println( "<h1>Hello Servlet ！</h1>" );
out.println( "</body>" ) ;
out.println( "</html>" ) ;
out.flush();// 刷新写入
}
}
配置文件web.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app 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"
version="2.5">
// Servlet文件路径
<servlet>
<servlet-name>query</servlet-name>
<servlet-class>com.kettas.servlet.GenDateServlet</servlet-class>
</servlet>
// 指定映射，说明在浏览器中输入".../query"则对应当前Servlet
<servlet-mapping>
<servlet-name>query</servlet-name>
<url-pattern>/query</url-pattern>
</servlet-mapping>
</web-app>
