springboot actuator

1、什么是actuator

线上监控工具

2、如何整合

遵循三板斧

第一步加依赖

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

第二步加注解

无

第三步加配置

无

启动后访问项目路径加上/actuator

 

 

 /actuator/health,作用健康检查。

在配置中加入

management.endpoint.health.show-details=always

可以检查如下这么多资源的健康状态
