RefreshEndpoint Bean 不适用于 Spring Boot 2.4.2 和 Spring Cloud 2020.0.1

Question

我有一个应用程序正在迁移到最新的 Spring Boot(2.4.2) 和 Spring Cloud(2020.0.1) 版本。该应用程序使用 Cloud Config Server 来获取配置，刷新由调用 RefreshEndpoint.refresh().

的计划作业完成

这曾经工作得很好，但是对于上面的版本，我不能让它工作。

Description:

Parameter 0 of constructor in io.divinedragon.spring.boot2.ConfigRefreshJob required a bean of type
'org.springframework.cloud.endpoint.RefreshEndpoint' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.cloud.endpoint.RefreshEndpoint' in your configuration.

这是具有以下配置的项目。

    @Scheduled(fixedDelay = TEN_MINUTE)
    public void refreshConfigs() {
        LOG.info("Refreshing Configurations - {}", refreshEndpoint.refresh());
    }
}

有人可以建议如何解决这个问题吗？

Answer 1

按如下方式更改您的 application.yml :

management:
  endpoints:
    web:
      exposure:
        include:
          - refresh
          - health

Refresh Scope

Answer 2

此外，您可能需要在 application.yml:

中启用 JMX

management:
  endpoints:
    web:
      exposure:
        include:
          - refresh
spring:
  jmx:
    enabled: true

查看此对话：https://github.com/spring-cloud/spring-cloud-commons/issues/710#issuecomment-598769493

我遇到了同样的问题，启用 JMX 有帮助。
