二十springboot之监控管理Actuator

Posted 2020-11-19 灬小乙

1.新增spring-boot-starter-actuator的依赖

　　gradle：

compile(‘org.springframework.boot:spring-boot-actuator‘)

　　maven：

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

2.重启项目

　　控制台会出现端点监控如下：

2018-06-22 11:13:27.648  INFO [wolong-member-provider,,,] 8684 --- [           main] o.s.b.a.e.mvc.EndpointHandlerMapping     : Mapped "{[/env/reset],methods=[POST]}" onto public java.util.Map<java.lang.String, java.lang.Object> org.springframework.cloud.context.environment.EnvironmentManagerMvcEndpoint.reset()

2018-06-22 11:13:27.654  INFO [wolong-member-provider,,,] 8684 --- [           main] o.s.b.a.e.mvc.EndpointHandlerMapping     : Mapped "{[/refresh || /refresh.json],methods=[POST]}" onto public java.lang.Object org.springframework.cloud.endpoint.GenericPostableMvcEndpoint.invoke()

3.端点介绍

　　原生端点

　　根据端点的作用来说，我们可以原生端点分为三大类：

• 应用配置类：获取应用程序中加载的应用配置、环境变量、自动化配置报告等与Spring Boot应用密切相关的配置类信息。
• 度量指标类：获取应用程序运行过程中用于监控的度量指标，比如：内存信息、线程池信息、HTTP请求统计等。
• 操作控制类：提供了对应用的关闭等操作类功能。
