Java JPA 2.1:can'；我无法访问数据库

伙计们！ 在重建以前正在工作的web项目后，我遇到了一个问题：无法使用working before config访问数据库。我试图通过main方法达到DB，但是结果是一样的。我有几个项目的备份，所有备份都无法访问数据库。 在persistence.xml中，我试图提到数据库的完整路径，但没有效果（以前这个配置很好）。 不幸的是，没有抛出异常，因此我无法找到问题所在

配置：JPA2.1、JDK1.8.060、Maven、Spring4.1

如果您能就如何跟踪和解决此问题提供任何建议，我将不胜感激

那么“够不着”和“不工作”的确切含义是什么？您会收到什么错误消息？你预计会发生什么？您发布的日志文件看起来不错，似乎没有任何错误。谢谢您的回答！问题是，尽管有完整的数据库路径，但应用程序无法访问它。事实证明，我有3个（！）不同的数据源路径：一个在persistence.xml中，另一个在application-config.xml中，最后一个在beans.xml中。我认为这种方法不是正确的，但在Web应用程序中应该提到唯一的数据源路径呢？这取决于如何初始化DB连接。如果使用LocalContainerEntityManagerFactoryBean，则不需要persistence.xml文件，因为可以在bean定义中指定所有配置。我不知道application-config.xml文件是什么，但我认为beans.xml文件中的数据库配置应该足够了。
