实现SpringBoot应用的优雅关机

1、pom.xml中增加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

2、application.properties配置属性

#启用shutdown
management.endpoint.shutdown.enabled=true
management.endpoints.web.exposure.include=*
# 自定义管理端前缀
management.endpoints.web.base-path=/saulala
# 自定义管理端端口
management.server.port=12581
# 指定本机地址作为管理端地址，不允许远程连接，保证安全
management.server.address=127.0.0.1

3、关闭服务的接口

curl -X POST 127.0.0.1:12581/saulala/shutdown

4、封装关闭脚本/home/myservice/scripts/shutdown.sh

#!/bin/bash
PORT=$(netstat -ntulp | grep 12580)
# 如果PORT不为空说明有程序占用该端口号
if [[ -n $PORT ]]; then
        echo "The server is open, ready to close"
        RESULT="000"
        while [[ $RESULT == "000" ]]; do
                echo "Closing down ..."
                # 优雅关闭springboot项目
                RESULT=$(curl -X POST 127.0.0.1:12581/saulala/shutdown)
                sleep 2
        done
        echo "Close off success"
fi
echo "Being started ..."

5、配置服务/usr/lib/systemd/system/myservice.service，并启用systemctl enable myservice.service

[Unit]
Description=myservice service
After=myservice.service

[Service]
Type=simple
NotifyAccess=all
TimeoutStartSec=0
Restart=on-failure
ExecStart=/home/myservice/jdk1.8.0_65/bin/java -jar /home/myservice/myservice-0.0.1.jar --spring.config.location=/home/myservice/application.properties> log.info 2>log.error &
ExecStop=/home/myservice/scripts/shutdown.sh 
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

6、启动、关闭服务

service start myservice
service stop myservice
