一、Actuator简介
监控应用,上报状态信息
二、开启监控
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
三、端点
Spring Boot 2.0的Actuator默认只暴露了health和info端点
1、开启其他端点
management:
server:
port: 8001
#开启所有端点
endpoints:
web:
exposure:
include: '*'
# 开启shutdown端点 调用关闭服务
endpoint:
shutdown:
enabled: true
2、查看所有端点请求路径 http://localhost:8001/actuator/

3、功能
//Health 显示系统状态
{"status":"UP"}
//shutdown 关闭服务
//使用Post方式请求端点
{
"message": "Shutting down, bye..."
}
//autoconfig 获取应用的自动化报告
//beans 获取应用上下文中创建的所有Bean
//configprops 获取应用中配置的属性信息报告
//env 获取应用所有可用的环境属性报告
//mappings 获取应用所有Spring Web的控制器映射关系报告
//info 获取应用自定义的信息
//metrics 返回应用的各类重要度量指标信息
//metrics节点并没有返回全量信息,我们可以通过不同的key去加载我们想要的值metrics/jvm.memory.max
//threaddump 返回程序运行中的线程信息
