LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository
07:54:41,514 [ContainerBackgroundProcessor[StandardEngine[Catalina]]] WARN ActiveManagementCoordinator : A C3P0Registry mbean is already registered. This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources.
部署之后，控制台提示这样的错误。请问大神们这到底是咋子回事咧！
应用 c3p0 类

异常信息是没有部署引起的，重新部署看下
