java - Hibernate:在没有 log4j 的情况下禁用日志记录到控制台

Question

我有 hibernate 模式，我想减少控制台每次运行时发生的日志记录。我的应用程序中没有 log4j，也不想添加它。

这是我每次运行我的应用程序时获得的日志示例

这是我的 hibernate.cfg.xml

根据您的日志详细信息，我了解到 Hibernate 版本是 Hibernate 4.0.4.Final。从 4.0 版开始，Hibernate 使用了JBoss 日志库，因此甚至您的应用程序不包含任何 log4j 仍然 hibernate 正在使用 JBoss 日志记录提供程序作为默认提供程序。有关更多信息，请访问此链接:

http://docs.jboss.org/hibernate/orm/4.3/topical/html/logging/Logging.html

希望此信息能帮助您理解为什么日志在没有任何 log4j 的情况下仍然可用。
