- I specify all the OpenJPA properties in a subclass of Spring's
org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration - see the class below. This is probably what I need to change, but how? And where to specify the properties file so openjpa-maven-plugin can find it?
如果您的OpenJPA分发jar损坏，或者
如果您的安全政策过于严格.
This can also occur if your OpenJPA distribution jars are corrupt, or
if your security policy is overly strict.
- 已排除-我检查并使用
checksumPolicy=fail重新下载了OpenJPA jar，以便证明它们没有损坏，而且我在该级别没有使用任何安全策略.
- ruled out - I checked redownloaded the OpenJPA jars with
checksumPolicy=fail so that's proof that they're not corrupted, plus I'm not using any security policy at this level.

推荐答案
这里的答案为我解决了.
This answer here sorted it out for me.
maven插件需要一个persistence.xml才能工作，这有点不干，因为我必须记住在其中列出任何新的实体bean，但我认为这是一个很小的价格.
The maven plugin needs a persistence.xml to work, which is slightly not DRY because I have to remember to list any new entity beans in there, but I figured it's a small price.
