[FIXED] Disable automatic logging configuration in spring boot

Issue

I use spring boot 1.2.1.RELEASE and noticed that spring automatically changes my log4j configuration on startup.

Here are my (spring) dependencies:

<!-- parent includes slf4j and log4j -->
<dependencies>
    <dependency>
        <!-- Import dependency management from Spring Boot -->
        <groupId>org.springframework.boot</groupId>

When I start my application with -Dlog4j.configuration=log4j-live.xml -Dlog4j.debug I can see that first my log4j config is used, then spring cleans it and installs its own config and then (this is what I guess) adds the default log4j.xml from the classpath.

How can I use only the default log4j behavior or how can I define which of my files spring shall use for configuration?

Cheers,

Jan

Solution

Spring Boot uses a logging system-agnostic property to override the default configuration:

If the environment contains a property logging.config then that will be used to initialize the logging system, otherwise a default location is used.

So use -Dlogging.config=log4j-live.xml -Dlog4j.debug instead.
