tomcat7中的servlet3的使用
在tomcat7中,文件结构完全可以没有web.xml了,而servlet可以通过注解来进行配置.下面就是一个简单的例子.同时eclipse3.6也支持servlet3.0的自动声明.而且servlet3.0采用了异步处理，性能明显得到了提升.
package com.phl.servlet;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;@WebServlet("/SReport")public class SReport extends HttpServlet {private static final long serialVersionUID = 1L; public SReport() { super(); }protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {doPost(request,response);}protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {PrintWriter out = response.getWriter();out.write("hello servlet3.0");}} 1 楼 kyfxbl 2011-06-01 用注解配置SERVLET，要迁移到老版本的TOMCAT或者别的容器就麻烦了
