javax.servlet.ServletException:创建bean时出错-调用init方法失败；嵌套异常是javax.persistence.PersistenceException

为什么我会在Apache服务器上的Java/Hibernate应用程序上遇到

javax.servlet.ServletException:javax.servlet.ServletException:javax.servlet.ServletException:Error creating bean

我总是通过重新启动整个站点来修复它。有什么建议吗

HTTP Status 500 -

我想，您正在使用不好的连接池。 当连接丢失时，您的连接池没有尝试重新建立连接

确保您的数据库始终可用。

您的意思是“beam”；还是bean？请包括完整的stacktrace，此stacktrace似乎不完整（它缺少异常原因链的stacktraces）。除了完整的stacktraces（检查日志！），还包括连接配置（或代码）。如果您正在使用

org.firebirdsql.pool

包中的任何内容，请查看。我强烈建议切换到

org.firebirdsql.ds

（如果在JavaEE中使用）中的等效类，或者切换到第三方连接池；还是bean？请包括完整的stacktrace，此stacktrace似乎不完整（它缺少异常原因链的stacktraces）。除了完整的stacktraces（检查日志！），还包括连接配置（或代码）。如果您正在使用
