Git从入门到起飞(详细)

1、配置

 ​​​​​​​

      在 Libray 中选 Java 选项（也就是安装Tomcat的路径）

如果运行时端口被占用可以修改端口

例如：原8080，可改为8081（也可修改其他）

2、使用Serlvet

package com.company;

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

@WebServlet("/hello") //请求
public class Exma extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.getWriter().write("Hello world!!");
    }

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