java - Spring:OnEnabledEndpointCondition 只能用于返回@Endpoint 或@EndpointExtension 的@Bean 方法

Question

我有一个 pet project (社交网络 Web 应用程序)，我使用 Spring Cloud 构建微服务基础设施。

我总是保留所有库的最新版本，所以目前我正在将 Spring Boot + Cloud 更新到以下版本:

springBootVersion = '2.0.0.M7'
springDataVersion = '2.0.0.M7'
springCloudVersion = 'Finchley.M4'

更新版本后，我的应用程序开始无法启动。例如，当我在 sn-user-service 中运行测试时，我得到以下堆栈跟踪:

问题是我在 Spring Docs 中找不到有用的东西。有人遇到过这个问题吗？

Answer 1

更新:Finchley M5 已发布。它与 Boot 2.0 M7 兼容。

在撰写本文时，Spring Cloud 还不兼容 Spring Boot 2.0.0.M7，即使在快照中也是如此。如果您想使用 Spring Cloud，您现在需要坚持使用 Spring Boot 2.0.0.M6。
