通过环境变量在Spring Boot中设置日志记录级别 [英] Set Logging Level in Spring Boot via Environment Variable

问题描述

在Spring Boot应用程序中是否可能仅通过环境变量设置日志记录级别?

Should it be possible to set logging levels through environment variables alone in a Spring Boot application?

我不想在Cloud Foundry上运行时使用application.properties，并且希望在不进行部署的情况下(但在应用重新启动或重新调整以更精确之后)进行更改.

I don't want to use application.properties as I'm running on Cloud Foundry and want to pick up changes without a deploy (but after the app has restarted, or restaged to be more precise).

我已经尝试设置像LOGGING_LEVEL_ORG_SPRINGFRAMEWORK=TRACE这样的env var，但这没有效果.但是，将logging.level.org.springframework: TRACE放入application.properties确实可以.

I've tried setting env vars like LOGGING_LEVEL_ORG_SPRINGFRAMEWORK=TRACE but that has no effect. Putting logging.level.org.springframework: TRACE in application.properties does work though.

推荐答案

这只是一个主意，但您是否尝试设置

This is just an idea, but did you try setting

_JAVA_OPTIONS=-Dlogging.level.org.springframework=TRACE?

理论上，这种方式-Dlogging.level.org.springframework=TRACE将作为默认的JVM参数传递，并且应该影响环境中的每个JVM实例.

Theoretically, this way -Dlogging.level.org.springframework=TRACE will be passed as default JVM argument and should affect every JVM instance in your environment.
