[Java] logback-spring.xml

Note that I was addicted to launching a spring-boot application from Eclipse.

Conclusion

Explicitly specified with LOGGING_CONFIG.

Background

`logback-spring.xml`


<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE logback>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsleAppender">
        <!--abridgement-->
    </appender>

    <!--abridgement-->

    <springProfile name="debug">
        <root level="DEBUG">
            <appender-ref ref="CONSOLE" />
        </root>
    </springProfile>

    <!--abridgement-->

</configuration>

If you start it from the command line with java -jar ... --spring.profiles.active = debug, you will get a DEBUG level log on the console.

On the other hand, when launched from Eclipse as a Java application, there was no DEBUG level log output to the console.

As a result of various trials, the log is output by setting the environment variable as follows in the environment of the execution configuration.

variable	value	Remarks
LOGGING_CONFIG	src/main/resources/logback-spring.xml	Relative path from the project root
SPRING_PROFILES_ACTIVE	debug	You may specify it by a method other than the environment variable.
