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

Question

我一直收到这个错误，我不知道从哪里开始。我是一个非常新的春天，并没有编码任何项目。我只是想尝试运行它，但无法让它运行起来。

以下是完整错误：

Jul 31, 2015 11:37:41 AM org.apache.catalina.core.StandardContext listenerStart

我只是想知道这意味着什么以及我可以通过哪些线索来寻找解决方案，因为我一整天都在寻找并找不到答案。谢谢！

org.eclipse.persistence.exceptions.EntityManagerSetupException

当新实体不在persistence.xml中时会发生。

  

内部异常：java.lang.IllegalArgumentException：属性eclipselink.logging.level具有非法值测试。

从上方可以看到，您的eclipselink.logging.level具有非法值。

因此您需要将其更改为有效值。

以下是可以使用的有效值。
