Does SLF4J work with Log4j2?
jar – Log4j 2 SLF4J binding. It allows applications coded to the SLF4J API to use Log4j2 as the implementation. log4j-api. jar – provides the adapter components required for implementers to create a logging implementation.
Do we need SLF4J with Log4j2?
We can directly use log4j2 without slf4j. But you are now locked to log4j2 library. So in future if you want to move to any other logging library. you have to go to all java files and change your logger statements.
Which is better SLF4J or Log4j2?
Conclusion. So essentially, SLF4J does not replace Log4j, Both work together. SLF4j removes the tight coupling between the application and logging frameworks. It makes it easy to replace with any other logging framework in the future with a more capable library.
What is the difference between SLF4J and Log4j2?
SLF4J is Simple Logging Facade for Java. It is not a logging component and it does not do the actual logging. It is only an abstraction layer to an underlying logging component. In the case of Log4j, it is a logging component and it does the logging instructed to do.
Does log4j use Logback?
Logback uses the same concepts as Log4j. So it’s no surprise that even if they are using different file formats, their configurations are very similar. The following code snippet shows the same configuration as I used with Log4j.
Is log4j different from log4j2?
Community support: Log4j 1. x is not actively maintained, whereas Log4j 2 has an active community where questions are answered, features are added and bugs are fixed. Automatically reload its configuration upon modification without losing log events while reconfiguring.
What is 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 Logback and slf4j?
SLF4J (Simple Logging Facade for Java) is a simple facade or abstraction for various logging frameworks, such as Java Util Logging (JUL), Logback and Log4j2. We use the abstract SLF4J API in the application, and later we can plug in any desired logging framework as underlying implementation.
What is the difference between SLF4J and Log4j?
Ssl4j is easy to use as the API’ and simple and straightforward
Why to use SLF4J?
– jcl-over-slf4j.jar: Adding this jar to our project will redirect all calls made to JCL – log4j-over-slf4j.jar: All calls to Log4j will point to SLF4J after you add this jar to your classpath – jul-to-slf4j.jar: This library translates JUL’s LogRecord objects to their SLF4J equivalent.
How to configure SLF4J?

How to get Liquibase to log using SLF4J?
Using the logLevel parameter. The logLevel is an optional parameter which can be set in the liquibase.properties file or specified on the command line. The logLevel specified on the command line will over-ride the value set in the liquibase.properties file. Examples: liquibase –logLevel=debug update liquibase –logLevel=info updateTestingRollback
