javax.servlet.ServletException : Error creating bean - Invocation of init method failed; nested exception is javax. 持久性.PersistenceException

Question

为什么我在 Apache 服务器上托管的 Java/Hibernate 应用程序上遇到 javax.servlet.ServletException: javax.servlet.ServletException: javax.servlet.ServletException: Error create bean ？

我总是通过重新启动整个网站来修复它。有什么建议吗？

HTTP Status 500 -

type Exception report

message

确保您的数据库始终可用。
