Spring Boot logs: iRAv2 format

Programming

Issue:

I have a Spring Boot application with different branches. One of the feature branches suddenly displays logs in iRAv2 format and omits some of the original log messages. No additional logging libraries are used other than the Spring Boot default.

iRAv2 format logs:

  .   ____          _            __ _ _
 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
 \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/

Jan 02 10:34:23 [iRAv2] No active profile set, falling back to default profiles: default | o.s.boot.SpringApplication:651

Correct format logs:

Answer:

The iRAv2 format logs are likely being caused by the use of the spring.profiles.active JVM system property. This property can be set to iRAv2 in the feature branch, causing the log messages to be formatted in this way. To fix this issue, ensure that the spring.profiles.active property is not set to iRAv2 in the feature branch. Alternatively, the logging format can be explicitly configured in the application.properties file using the logging.pattern.console property.
