Servlet的@WebServlet注解

编写好Servlet之后,要告诉Web容器有关这个Servlet的一些信息.

在Servlet3.0中,可以使用标注(Annotation)来告诉容器哪些Servlet会提供服务以及额外的信息

写个例子:

package cn.my.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * Servlet implementation class MyServlet */@WebServlet("/hello.do")public class MyServlet extends HttpServlet {  private static final long serialVersionUID = 1L;      protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        System.out.println("hello");    }  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {    doGet(request, response);  }}
