我正在开发一个项目，最近我们从tomcat7升级到了tomcat8。之后，我们的应用程序的日志文件中出现了一些额外的日志记录，即使我们从未将这些行放在任何地方。以下是日志文件的示例：
2015-05-07T23:24:45.809Z DEBUG ClasspathScanner : Starting classpath scanning...

ClasspathScanner，Version，DefaultTraversableResolver，ValidationXmlParser和LifecycleManager不在我的代码中。
它们似乎与hibernate相关，但hibernate未列出我们的pom文件。 Hibernate确实存在于生成的类路径中，但它自项目开始就已存在。
有没有人知道这些日志记录的来源以及如何禁用它们？
