Logback is a reliable, fast and flexible logging framework for Java, intended as the successor to log4j 1.x. It natively implements the SLF4J API and is divided into logback-core, logback-classic, and logback-access modules.
Use cases
- add structured logging to a Java application
- replace log4j 1.x with a maintained logging framework
- implement SLF4J logging in a Spring Boot service
- capture HTTP access logs in Tomcat or Jetty
- configure rolling log files and log levels
- switch logging backends without changing application code
When to choose
- you need a mature, widely adopted SLF4J-native logging implementation for the JVM
- you are migrating away from log4j 1.x or java.util.logging
- you need flexible configuration of appenders, filters, and rolling policies
When to avoid
- you are not on the JVM or need logging for another language
- you need a minimal zero-dependency logging facade only (SLF4J alone may suffice)
- you require async-first structured logging with JSON output out of the box (consider Log4j2 or dedicated structured loggers)
