我在 Spring 应用程序中使用 java.util.logging。

而不是看到这种格式的日志输出:

21:26:09,406 (main) INFO  DataNucleus.Datastore.Schema - Creating table null.DataNucleus_TABLES

我刚刚看到这个:

21:26:09,406 Creating table null.DataNucleus_TABLES

要显示的输出有这么多不同的选项，我将所有这些选项都包括在内，因为我无法分辨我正在查看哪个类别。那么，要启用的最高级别设置是什么，以便我只需为所有 DataNucleus 日志类别设置单一日志级别？

输出的格式取决于您的日志记录配置，DN 文档中引用的格式适用于 Log4J(我们使用的)，带有格式化程序。仅当您希望所有类别具有相同的日志记录级别时才设置类别“DataNucleus”，因为它是父类别
