Tomcat生命周期异常LifecycleException:无法启动组件[StandardEngine[Catalina]。标准主机[本地主机]。标准上下文

Question

我已经看了这个问题，但我不知道如何解决它...许多答案谈到servlet配置错误，但没有说明如何修复它以及要更改什么。我的catalina日志文件看起来像这样：

  org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/flowable-modeler]]

我必须改变什么？

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，这是以下例外。它指向某些数据源连接，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。
