How do you query the EclipseLink version at runtime (plus JPA meta data)?

问题

Question pretty much says it all.

Is there an equivalent for org.hibernate.Version.getVersionString() in EclipseLink?

Why isn't there a portable (JPA) way to query provider information in general?

回答1:

Never used it but from the Eclipselink javadoc you could try the following class:

org.eclipse.persistence.Version

回答2:

There is a static class and static method to get this information.

Example: How to print in java code

AbstractSessionLog.getLog().log(SessionLog.INFO, DatabaseLogin.getVersion());
