删除 BackgroundPreinitializer 上不相关的日志

问题描述

编辑我现在无法升级 tomcat，因此相关答案与此处无关

我们正在使用 8.5.50 并遇到 bug 产生的日志：

我未能使用应用程序的 log4j 和 tomcat/conf/logging.properties 删除日志

messageinterpolation.ResourceBundleMessageInterpolator.level = INFO
org.hibernate.validator.messageinterpolation.ResourceBundleMessageInterpolator.level = INFO

如何删除此类日志？

解决方法

Hibernate 4.x 及更高版本使用 JBoss Logging 作为日志记录接口（参见 documentation）。为了忽略这些消息，您需要确定生成它们的日志系统。

使用您的依赖项，所有 Hibernate 消息都应转到 Log4j 2。设置：

<Logger name="org.hibernate.validator.messageinterpolation" level="INFO" />

应该禁用消息。

备注：您的 Log4j 1.x 日志系统配置错误：您同时拥有 log4j 和 log4j-over-slf4j（Log4j 1.x 的替代品，它将所有内容发送到 SLF4j ) 在您的依赖项中。随机选择这两种实现中的哪一种。
