JavaWeb的servlet的doGet,doPost方法

package top.lostyou.servlet;

import com.sun.scenario.effect.impl.sw.sse.SSEBlend_SRC_OUTPeer;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

public class HelloServlet extends HttpServlet{
    //由于get或者post只是请求实现的不同的方式,可以相互调用,业务逻辑都一样
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        System.out.println("进入doget方法");
      PrintWriter writer=resp.getWriter();//响应流
        writer.print("Hello servlet");

    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doPost(req, resp);
    }
}
