Why do we need SLF4J?

This is the main purpose of SLF4J (Simple Logging Facade for Java) – a logging abstraction which helps to decouple your application from the underlying logger by allowing it to be plugged in – at runtime. Of course, the flexibility that such an abstraction provides is the main reason to use SLF4J.

What is the use of SLF4J in Java?

The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks, such as java.util.logging, logback and log4j. SLF4J allows the end-user to plug in the desired logging framework at deployment time.

What is logger factory in Java?

The LoggerFactory is a utility class producing Loggers for various logging APIs, most notably for NLOG4J and JDK 1.4 logging. Other implementations such as NOPLogger and SimpleLogger are also supported. LoggerFactory is essentially a wrapper around an ILoggerFactory instance bound with LoggerFactory at compile time.

Does SLF4J use Commons Logging?

By making commons-logging provided, you are telling Maven to include it during build time for any component in your code which needs it (e.g. something like Spring), but to exclude it at runtime, in the final JAR output. Instead, the bridge JAR jcl-over-slf4j.

What is org SLF4J logger?

SLF4J stands for Simple Logging Facade for Java. It provides a simple abstraction of all the logging frameworks. It enables a user to work with any of the logging frameworks such as Log4j, Logback, JUL (java. util.

What is SLF4J vs log4j?

Unlike log4j, SLF4J (Simple Logging Facade for Java) is not an implementation of logging framework, it is an abstraction for all those logging frameworks in Java similar to log4J. Therefore, you cannot compare both. If you have a choice, logging abstraction is always preferable than logging framework.

What is logger SLF4J?

Simple Logging Facade for Java (abbreviated SLF4J) – acts as a facade for different logging frameworks (e.g. java. util. logging, logback, Log4j). It offers a generic API making the logging independent of the actual implementation. This allows for different logging frameworks to coexist.

Is SLF4J logger thread safe?

Logger is thread-safe (search for “multi-thread safe”)

What is Lombok SLF4J?
