springboot2.x下actuator模块

一、简介
    spring-boot-starter-actuator模块是一个spring提供的监控模块。我们在开运行发过程中，需要实时和定时监控服务的各项状态和可用性。Spring Boot的spring-boot-starter-actuator 模块（健康监控）功能提供了很多监控所需的接口，可以对应用系统进行配置查看、相关功能统计等。
二、实现
    在maven的pom中引入：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
如果使用HTTP调用的方式，还需要这个依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

三、配置

    1、health：配置

spring:
  application:
    name: spring-cloud-consul-consumer
server:
  port: 8803
 
management: 
  server: 
    port: 54001  #如果不配置，默认与服务端口一致
  health:
    db:
      enabled: true
    mail:
      enabled: true
  endpoint:
    env:
      enabled: true
  endpoints:
    web:
      exposure:
        include: "*"

 访问：http://localhost:54001/health 这是springboot1.x的访问

springboot2.x 后 http://localhost:54001/actuator/health

结果：

2、info：配置

info: 
  app:
    name: "@project.name@" #从pom.xml中获取
    description: "@project.description@"
    version: "@project.version@"
    spring-boot-version: "@project.parent.version@"

访问：http://localhost:54001/actuator/info

{"app":{"name":"demo","description":"Demo project for Spring Boot","version":"0.0.1-SNAPSHOT","spring-boot-version":"2.1.0.RELEASE"}}
