java - Tomcat 生命周期异常 LifecycleException : Failed to start component [StandardEngine[Catalina]. StandardHost[localhost].StandardContext

Question

我已经查看过这个问题，但我不知道如何解决它...许多答案都在谈论 servlet 配置错误，但没有说明如何解决它以及要更改的内容。我的 Catalina 日志文件如下所示:

在此之后我有一系列这样的警告:

我需要更改什么？

Answer 1

始终查看堆栈跟踪的底部以找到根本原因。在您的情况下，它是以下异常。它指向一些数据源连接并在初始化时确定数据库类型。您可能需要检查配置中的数据库连接属性。
