一:通过HTTP发送shutdown信号
该方式主要依赖Spring Boot Actuator的endpoint特性,具体步骤如下:
1. 在pom.xml中引入actuator依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
2. 开启shutdown endpoint
Spring Boot Actuator的shutdown endpoint默认是关闭的,因此在application.properties中开启shutdown endpoint:
#启用shutdown
endpoints.shutdown.enabled=true
#禁用密码验证
endpoints.shutdown.sensitive=false
3. 发送shutdown信号
shutdown的默认url为host:port/shutdown,当需要停止服务时,向服务器post该请求即可,如:
curl -X POST host:port/shutdown
将得到形如{“message”:”Shutting down, bye…”}的响应
4. 安全设置
可以看出,使用该方法可以非常方便的进行远程操作,但是需要注意的是,正式使用时,必须对该请求进行必要的安全设置,比如借助spring-boot-starter-security进行身份认证:
pom.xml添加security依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
开启安全验证
在application.properties中变更配置,并
#开启shutdown的安全验证
endpoints.shutdown.sensitive=true
#验证用户名
security.user.name=admin
#验证密码
security.user.password=secret
#角色
management.security.role=SUPERUSER
指定路径、IP、端口
#指定shutdown endpoint的路径
endpoints.shutdown.path=/custompath
#也可以统一指定所有endpoints的路径`management.context-path=/manage`
#指定管理端口和IP
management.port=8081
management.address=127.0.0.1
二、创建启动脚本boot.sh 一下是脚本内容
