## 1.2.springBoot启动类代码 ##

package com.example.demo;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class DemoApplication { 
    
       public static void main(String[] args) { 
          SpringApplication.run(DemoApplication.class, args);
       }
    
    }

## 1.3.案例demo ##

package com.example.demo;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RequestMapping("/")
    @RestController
    public class HelloController { 
        private static final Logger logger = LoggerFactory.getLogger(HelloController.class);
    
        @RequestMapping("/hello")
        public String hello() { 
            logger.info("111");
            logger.info("222");
            logger.info("333");
            logger.info("444");
    
            return "Hello Spring Boot!";
        }
    
    }

## 1.4.application.properties的内容如下 ##

server.port=8060
    server.tomcat.uri-encoding=utf-8

注意：  
1、容器内部使用http://localhost:8060/hello即可访问到接口。  
2、由于笔者使用的是docker容器部署的，宿主机上的18060和容器内部的8060端口映射，所以在浏览器上可以使用：http://localhost:18060/hello进行访问。

启动之后的效果如下：

# 2.打包部署 #

最终打的包是：demo-0.0.1-SNAPSHOT.jar，假设放在docker容器里面的/root/workspace位置。如下图：

## 2.1.编写start.sh ##

内容如下：

cd /root/workspace
    
    source /etc/profile
    nohup java -jar -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5000 demo-0.0.1-SNAPSHOT.jar  > demo.log 2>&1 &

**注意，主要添加：**

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5000

其中5000就是实际用于调试用的端口(docker宿主机上的15000和容器内部的5000映射，具体命令略)。

## 2.2.访问验证 ##

启动之后，在本地的浏览器中访问：http://localhost:18060/hello，效果图如下：

# 3.在idea中配置远程调试端口 #

## 3.1.远程配置 ##

远程端口配置方式：

## 3.2.打断点 ##

## 3.3.访问页面 ##
