Logging using SLF4J
One of the popular logging frameworks being used with Java is Simple Logging Façade for Java, or SLF4J. It is one of the most widely used frameworks since it allows users to use any logging frameworks, such as Log4j, Logback, the java.util.logging package, or Java’s own logging engine, JUL, using only a single dependency. This means that we can switch from one logging framework to another depending on what is needed.
There are several advantages to using SLF4J:
- SLF4J enables us to switch from one framework to another at runtime or deployment.
- SLF4J has a migrator tool that allows us to migrate existing projects using the Java Class Library from Log4j to SLF4J.
- SLF4J supports parameterized logging messages to bind dynamic values for our logs.
- SLF4J decouples the application from the logging framework. We do not need to worry about which logging framework is being used when developing our application.
