Log control and management can still be well supported through system attributes and traditional SpringBook external configuration files.
Naming Specifications for Different Logging Systems
Logback:logback-spring.xml logbak-spring.proovy logback.xml logback.groovy
Log4j:log4j-spring.properties log4j-spring.xml log4j.properties log4j.xml
Log4j2:log4j2-spring.xml log4j2.xml
JDK(Java Util Logging):logging.properties
SpringBoot officially recommends using the file name with - spring as the log configuration file.
If you do not want to use the specified configuration file name, you can specify in the configuration file:
logging.config=classpath:logging-config.xml
Realization
New File--logback-spring.xml under project src/main/resource
