Which one is better log4j or SLF4J?
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. If you have a choice, logging abstraction is always preferable than logging framework.
Which logger is best for spring boot?
Logback
If you are using Spring Boot Starters, Logback will provide a good support for logging. Besides, Logback also provides a use of good support for Common Logging, Util Logging, Log4J, and SLF4J.
Can we use log4j and slf4j together?
So essentially, SLF4J does not replace log4j; they both work together. It removes the dependency on log4j from your application and makes it easy to replace it in the future with the more capable library.
Why do we need log4j?
log4j is a tool to help the programmer output log statements to a variety of output targets. In case of problems with an application, it is helpful to enable logging so that the problem can be located. With log4j it is possible to enable logging at runtime without modifying the application binary.
What is difference between Log4j and Logback?
Log4j has been defined as java based application with logging utility which is the java framework for logging messages to a different output, which helps enable to locate the problems. Logback is defined as the successor to log4j, which is also a java framework for logging messages in any java based applications.
Which is better Log4j or SLF4J for Java?
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. However, it is always difficult to prefer one between the two.
Which is better for garbage collector SLF4J or log4j?
Since SLF4J uses less number of temporary strings means less work for the garbage collector, which means better throughput and performance for your application. So essentially, SLF4J does not replace log4j; they both work together.
Which is the best logging framework for Java?
So Basically Simple Logging Facade for Java serves as a simple facade or abstraction for various logging frameworks allowing the end user to plug in the desired logging framework at deployment time. Log4j,Logback and java.util.Logger are logging libraries which actually write the logs and have their own pros and cons.
What’s the difference between Simple Logging Facade in Java?
Explains the differences in detail. So Basically Simple Logging Facade for Java serves as a simple facade or abstraction for various logging frameworks allowing the end user to plug in the desired logging framework at deployment time.
