Actuator (motivator; actuator) is a straight module Spring Boot provided for monitoring the project. Which realize different monitoring functions through different monitoring terminal. Its function is similar to the monitoring center of Dubbo, the difference is, the monitoring center of Dubbo is the need for specialized deployments, and the Actuator Spring Boot is present in every project.

Second, the dependence

Just a Spring Boot project can be monitored using the Actuator.

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

Third, the configuration

#-----------------------------------Actuator监控器------------------------------------
#  Actuator监控端口与控制中心,默认只开启info、与health监控
#  http://localhost:9999/actuator/beans
management:
  server:
    port: 9999 #设置Actuator监控端口
  endpoints:
    web:
      exposure:
        include: '*' #打开Actuator所有监控
        #exclude: ['env','beans']
      base-path: /actuator #设置Actuator监控基本路径

#-----------------------------------INFO------------------------------------
#自定义INFO信息
#浏览器访问 http://localhost:9999/actuator/info
info:
  company:
    name: '公司名称'
    url: 'www.xxxx'
    addr: 'china'

Fourth, test access
