Question

是否有系统属性使Slf4J和Logback告诉它找到了哪些logback.xml和logback-test.xml文件以及它使用了哪个？我希望在日志本身或System.out中看到它。

例如，我有一个明显没有src/main/resources/logback.xml或src/test/resources/logback-test.xml文件的Java项目，但是当我运行单元测试时，Logback确实找到了一个。我确实有多达100个依赖项（理论上没有一个应该包含logback.xml）并且逐个检查它们是不切实际的。

请注意，我无法在配置文件中使用<configuration debug="true">，因为我不知道配置文件的开头位置。我想要同样的效果。

在评论中使用Tony所述的-Dlogback.debug=true。然后显示：

15:14:22,155 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback.groovy]
15:14:22,156 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback-test.xml] at [file:/.../target/test-classes/logback-test.xml]
15:14:22,333 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.ConsoleAppender]
15:14:22,338 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [consoleAppender]

15:14:22,380 |-INFO in ch.qos.logback.classic.joran.JoranConfigurator@1e965684 - Registering current configuration as safe fallback point

具体来说，这条线很重要：

... - Found resource [logback-test.xml] at [file:/.../target/test-classes/logback-test.xml]

如果没有显示，则使用默认日志记录配置（所有DEBUG）或不识别系统属性。祝你好运找出它是哪种情况（vote for this jira）。

哪个配置文件是Logback使用的？
