我有一个弹簧启动应用程序，在初始化初始化之前，在启动时输出大约1500行JNDI调试日志记录到stdout。有没有人知道导致这种情况的原因以及是否有办法在此之前初始化回归？我有-Dlogback.debug = true，但它没有多大帮助。

使用自定义logback-spring.xml时，我也看到了Spring Boot 1.5.1。如果logback-spring.xml不存在，则不会出现调试语句。
我能够通过禁用JNDIPropertySource解决它。在类路径根目录中创建一个文件spring.properties：
# Disable the JNDIPropertySource. This avoids dozens of spurious DEBUG messages
# when starting up with a custom logback-spring.xml. We're not alone:
# http://stackoverflow.com/questions/42446013/spring-jndi-logging-before-logback-is-initialized
spring.jndi.ignore=true
spring.jndi.ignore已添加到https://jira.spring.io/browse/SPR-14026。
这种方法感觉很乱，但由于我没有在JNDI有用的容器中运行，它对我来说并没有破坏任何东西。

我也有同样的问题，但我无法关闭jndi，因为我的应用程序在启动时使用它。经过一些研究，我最终得到了解决方案：
1）将logback-spring.xml重命名为其他名称，例如logback-config.xml
2）将logging.config属性放入application.properties文件。
结果，您的配置将仅在spring启动时应用，并且将跳过此调试日志记录。同样在我的情况下，第一个解决方案没有工作，因为我需要jndi，在这种情况下你也可以启用jndi。
更新：这只对本地环境有帮助，在远程tomcat上做同样的工作并从catalina.log文件中删除这个调试日志，我最终将这个logback文件重命名为logback.xml因此，在jndi查找之前，它在启动时找到了。

您可以通过将此行添加到您的logback xml文件来避免这种情况
