我创建了一个使用 MongoDB 实现 hibernate OGM 的应用程序。它在 Eclipse 中运行得很好，但是，当我构建一个 fat jar 并尝试运行它时，出现以下错误:

Exception in thread "main" org.hibernate.service.UnknownServiceException: Unknown service requested [org.hibernate.ogm.service.impl.OgmConfigurationService]

就我而言，我在类路径中拥有所有正确的依赖项。我正在使用 JDK 11 并使用 https://github.com/johnrengelman/shadow 编译 fat jar 。

Đây là của tôi persistence.xml:

通过不再使用“fat jar”并将依赖项保留在各自的 jar 中，解决了这个问题。 Jar 合并导致服务解析变得复杂，从而产生 UnknownServiceException.

关于java - org.hibernate.service.UnknownServiceException : Unknown service requested [org. hibernate.ogm.service.impl.OgmConfigurationService]，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57980669/
