What is default CONSOLE_LOG_PATTERN used for Spring Boot logging and where to find it?

Solution 1:

I have just found out this configuration is available at the DefaultLogbackConfiguration file under Spring Boot project:

private static final String CONSOLE_LOG_PATTERN = "%clr(%d{${LOG_DATEFORMAT_PATTERN:-yyyy-MM-dd HH:mm:ss.SSS}}){faint} "
            + "%clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} "
            + "%clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} "
            + "%clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}";

To find the pattern for a certain Spring Boot version, either:

• Browse the source file available at GitHub: Spring Boot 2.3.x
• In IntelliJ Idea press 2x Left Shift and fulltext search for DefaultLogbackConfiguration
