How do I change Log4j to Logback?
Migrating from Log4j to Logback
- Remove the Log4j dependencies and add the Logback dependencies.
- Retrieve the logger instance using LoggerFactory.
- If you have any fatal logs, change them to error because SLF4J does not support fatal. If you still want to use something similar to fatal, use markers.
- Replace the log4j.

Finally, we demonstrated that Logback does actually filter any statement less than an error. 5.3.

When to use Logback to print the stack trace?
Also, when an Exception is passed as the last argument to a logging method, Logback will print the stack trace for us. 6. Detailed Configuration In the previous examples, we were using the 11-line configuration file we created in section 4 to print log messages to the console.

To log a message to Logback, we initialize a Logger from SLF4J or Logback: Then we use it: This is our logging context. When we created it, we passed LoggerFactory our class. This gives the Logger a name (there is also an overload that accepts a String).
