java“调用init方法失败；嵌套异常为javax.persistence.PersistenceException”是什么意思？

Question

我不断地犯这个错误，我甚至不知道从哪里开始。我对spring非常陌生，没有编写任何项目代码。我只是试图运行它，但无法让它工作

以下是全部错误：

我只是想知道这意味着什么，以及我可以通过哪些线索来找到解决方案，因为我已经搜索了一整天，却找不到答案。谢谢

org.eclipse.persistence.exceptions.EntityManagerSetupException

当一个新实体不在persistence.xml中时会发生这种情况

Internal Exception: java.lang.IllegalArgumentException: Property eclipselink.logging.level has an illegal value test.

从上面可以看到，您的eclipselink.logging.level有一个非法值

因此，您需要将其更改为有效值

以下是可以使用的有效值
