用myeclipse新建一个serlvet。

用myeclipse创建一个servlet，按默认选项自动生成一些方法：
[java] view plaincopy

package test;

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 TestServlet extends HttpServlet { public TestServlet() {

//构造方法

 System.out.print("---构造方法---");

}

public void destroy() {

 super.destroy();//销毁方法

 System.out.print("---销毁方法---");

} public void doGet(HttpServletRequest request, HttpServletResponse response)

 throws ServletException, IOException { response.setContentType("textml");

 PrintWriter out = response.getWriter();

 out

 .println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");

 out.println("<HTML>");

 out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");

 out.println(" <BODY>");

 out.print(" This is ");

 System.out.print("---doGet方法---");

 out.print(this.getClass());

 out.println(", using the GET method");

 out.println(" </BODY>");

 out.println("</HTML>");

 out.flush();

 out.close();

}

public void doPost(HttpServletRequest request, HttpServletResponse response)

 throws ServletException, IOException { response.setContentType("textml");

 PrintWriter out = response.getWriter();

 out

 .println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");

 out.println("<HTML>");

 out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");

 out.println(" <BODY>");

 out.print(" This is ");

 System.out.print("---doPost方法---");

 out.print(this.getClass());

 out.println(", using the POST method");

 out.println(" </BODY>");

 out.println("</HTML>");

 out.flush();

 out.close();

} /**

 * Initialization of the servlet. 

 *

 * @throws ServletException if an error occurs

 */

public void init() throws ServletException {

 //初始化方法

 System.out.print("---初始化方法---");

}}


web.xm则也会自动进行配置：
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>test.TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/servlet/TestServlet</url-pattern>
</servlet-mapping>
