搭建你的第一个Servlet-纯图版

package ct.shiro.test1; /**

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;
import java.io.PrintWriter;

@WebServlet(name = "ServletDemo", value = "/ServletDemo")
public class ServletDemo extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter writer = response.getWriter();
        writer.println("doGet");
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter writer = response.getWriter();
        writer.println("doPost");
    }

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
//        super.service(req, resp);
        PrintWriter writer = resp.getWriter();
        writer.println("service");
    }

    @Override
    public void destroy() {
        System.out.println("destory");
//        super.destroy();
    }

    @Override
    public void init() throws ServletException {
        System.out.println("init()");
//        super.init();
    }
}

直接运行tomcat此时还不行

需要从web.xml配置路由



停止时才会运行destory()
