Spring Boot - Profile-specific Logback configuration selection in logback-spring.xml file

[Last Updated: Nov 9, 2017]

Spring Boot allows to use <springProfile> tag to conditionally include or exclude sections of configurations based on the active Spring profiles. Profile sections are supported within the <configuration> element of logback configuration file.

Example

src\main\resources\logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <springProfile name="dev">
                <pattern>%d{yy-MMMM-dd HH:mm:ss:SSS} %5p %t %c{2}:%L - %m%n</pattern>
            </springProfile>
            <springProfile name="prod">
                <pattern>%d{yy-MM-dd E HH:mm:ss.SSS} %5p %t %c{2}:%L - %m%n</pattern>
            </springProfile>
        </encoder>
    </appender>
    <springProfile name="dev">
        <root level="DEBUG">
            <appender-ref ref="stdout"/>
        </root>
    </springProfile>
    <springProfile name="prod">
        <root level="INFO">
            <appender-ref ref="stdout"/>
        </root>
    </springProfile>
</configuration>

src/main/resources/application.properties

spring.main.banner-mode=off
spring.main.logStartupInfo=false
spring.profiles.active=prod
@SpringBootApplication
public class ExampleMain {
  private static final Logger logger = LoggerFactory.getLogger(ExampleMain.class);

  public static void main(String[] args) throws InterruptedException {
      SpringApplication.run(ExampleMain.class, args);
      logger.info("just a test info log");
  }
}

Output

Let's use 'dev' as active profile:
