Collecting Metrics

只要类路径上存在正确的依赖关系，Spring Cloud Circuit Breaker Resilience4j 就包含自动配置以设置度量集合。要启用度量集合，你必须包括 org.springframework.boot:spring-boot-starter-actuator 和 io.github.resilience4j:resilience4j-micrometer。要获取当这些依赖关系存在时生成的度量的更多信息，请参见 Resilience4j documentation。

Spring Cloud Circuit Breaker Resilience4j includes auto-configuration to setup metrics collection as long as the right dependencies are on the classpath. To enable metric collection you must include org.springframework.boot:spring-boot-starter-actuator, and io.github.resilience4j:resilience4j-micrometer. For more information on the metrics that get produced when these dependencies are present, see the Resilience4j documentation.

你无需直接包含 micrometer-core，因为它是由 spring-boot-starter-actuator 带入的。

You don’t have to include micrometer-core directly as it is brought in by spring-boot-starter-actuator
