Hibernate 5.3 Spring 5,Ehcache 3.5.2,jdk 10,Hibernate 说 "Cache provider not started"

Hibernate 5.3 Spring 5, Ehcache 3.5.2, jdk 10, Hibernate says "Cache provider not started"

...我的问题是,有了这个配置,我需要 "start" ehcache 吗?如果是,如何?这是一个通过库依赖项工作的迷宫,例如需要 hibernate-ehcache 和 ehcache 吗?需要 hibernate-jcache 吗?这是调试 3 天后 tomcat 9 标准输出的最终错误:

也造成了休眠问题 https://hibernate.atlassian.net/browse/HHH-12635

我不确定在 Hibernate 中创建问题是个好主意。这很可能是您这边的配置问题。

我要说的第一件事是 hibernate-ehcache 不应该存在。这是用于Ehcache 2。不是JCache+Ehcache3。

那么,能否请您尝试将 jcache.xml 重命名为 ehcache.xml

最后,不,你应该不需要启动提供的。它应该自己开始。

Henri 说得对,我不需要 hibernate-ehcache。但是不需要将 jcache.xml 重命名为 ehcache.xml。

简而言之,解决我的错误的方法是将 jcache.xml 资源添加到我的 ant 构建中,因为它没有被部署。话虽如此,对于可能有此错误的其他人来说,对于 hibernate 5.3,spring 5,ehcache 3.5.2,jdk 10,存在如此多的可能性和缺乏明确的简单愚蠢配置, tomcat 9,你唯一的希望(除了运气,它确实有效)是将 tomcat 置于调试模式,附加 eclipse,将 hibernate-core 源添加到 eclipse 项目,在有问题的休眠 class/method 并查看在您的特定配置中什么不是 available/expected。

对于其他试图使这项工作有效的人来说,奇怪的是,我确实需要 spring-boot-starter-cache,如果没有它,我的 spring 休眠配置的 none 会被读取。我是 13 岁的 Spring 2.5 人,所以我还没有理解 spring 引导是什么。它应该是 "opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss"。但它似乎也是一个 runtime/embedded tomcat,所以不管怎样,我确信它有时非常有用,而且相当不确定并且使其他人感到困惑....
