生产环境的监控。

依赖

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

终结点

提供应用程序监控的路由。

配置application.yml，才能看到后面的各种指标

management:
  security:
    enabled: false

/beans

敏感。输出应用程序中的所有Bean。

            {
                "bean": "swaggerApiListingReader",

Endpoint

包：org.springframework.boot.actuate.endpoint

public interface Endpoint<T> {  
    String getId();  
    boolean isEnabled();  
    boolean isSensitive();  
    T invoke();  
}

Endpoint的加载还是要依靠spring.factories实现的。Spring-boot-actutor包下的META-IN/spring.factories配置了EndpointAutoConfiguration。
