java - HHH90001006：缺少缓存 [default-update-timestamps-region] 是即时创建的

Question

一个简单的Spring Boot 2.5 应用程序，带有带有 EhCache 3 的 Spring Data JPA 和启用了查询和二级缓存的 Hibernate 5：

spring.jpa.properties.hibernate.cache.use_query_cache=true
spring.jpa.properties.hibernate.cache.use_second_level_cache=true

在启动时为每个缓存生成来自 Hibernate 的警告和来自 EhCache 的信息消息：

WARN org.hibernate.orm.cache          HHH90001006: Missing cache[default-update-timestamps-region] was created on-the-fly. The created cache will use a provider-specific default configuration: make sure you defined one. You can disable this warning by setting 'hibernate.javax.cache.missing_cache_strategy' to 'create'.
INFO org.ehcache.core.EhcacheManager  Cache 'default-update-timestamps-region' created in EhcacheManager.

和

WARN org.hibernate.orm.cache          HHH90001006: Missing cache[default-query-results-region] was created on-the-fly. The created cache will use a provider-specific default configuration: make sure you defined one. You can disable this warning by setting 'hibernate.javax.cache.missing_cache_strategy' to 'create'.
INFO org.ehcache.core.EhcacheManager  Cache 'default-query-results-region' created in EhcacheManager.

这些 Hibernate 缓存的正确 EhCache 配置是什么？

这是一个很好的解释：https ://www.ehcache.org/documentation/2.8/integrations/hibernate.html#configure-

如果您希望这些警告消失，您可以在 ehcache.xml 中明确定义缓存，或者使用create配置值作为警告日志。
