Which is better SLF4J or 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. However, it is always difficult to prefer one between the two.
Can we use SLF4J instead of Log4j?
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.
Does SLF4J API uses Log4j?
SLF4J supports popular logging frameworks, namely log4j, java. util. logging, Simple logging and NOP.
Do we need SLF4J with Log4j2?
It’s safe: the Log4j2 API offers the exact same guarantees as slf4j – and more. Now that Log4j2 itself is separated into an API and an implementation module, there is no longer any value in using SLF4J.
Does SLF4J have vulnerabilities?
The SLF4J API is just an API which lets message data go through. As such, using log4j 2. x, even via SLF4J does not mitigate the vulnerability.
Which logger is best for Java?
One of the most popular solutions for the Java world is the Apache Log4j 2 framework. Maintained by the Apache Foundation, Log4j 2 is an improvement on the original Log4j, which was the most popular logging framework in Java for many years.
Is Log4j over SLF4J affected by Log4j vulnerability?
No. Using Log4j 2. x via the SLF4J Application Programming Interface does not mitigate the vulnerability.
Should you use 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.
Is SLF4J impacted by log4j vulnerability?
Which version of SLF4J is not vulnerable?
slf4j:slf4j-ext package. This does not include vulnerabilities belonging to this package’s dependencies. Automatically find and fix vulnerabilities affecting your projects.
Which logger is best for spring boot?
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.
What is the alternative for Log4j?
SLF4J, Logback, Logstash, Castle Core, and Loki are the most popular alternatives and competitors to Log4j.
Is Log4j over slf4j safe?
If you are using log4j-over-slf4j. jar in conjunction with the SLF4J API, you are safe unless the underlying implementation is log4j 2.
Which version of slf4j is not vulnerable?
Is Lombok slf4j vulnerable?
Lombok is a build-time only dependency; there is no need for lombok. jar to be available when your application is run, it just needs to be there when you compile your code. Therefore, lombok is highly unlikely to be a source of security vulnerabilities.
Is SLF4J impacted by Log4j vulnerability?
Is Logback better than Log4j?
Key Difference Between Log4j vs Logback
As logback is improved, version log4j and versions log4j2 and logback have no difference in terms of performance or any features. Therefore log4j is the most used logging utility before the logback newer versions were invented.
Does spring use Log4j?
Spring Boot also supports either Log4j or Log4j 2 for logging configuration, but only if one of them is on the classpath. If you are using the starter poms for assembling dependencies that means you have to exclude Logback and then include your chosen version of Log4j instead.
Why do we need SLF4J?
Which is the best logging framework in Java?
What is the difference between Log4j and 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 Lombok SLF4J?
Annotation Type Slf4j
Causes lombok to generate a logger field. Complete documentation is found at the project lombok features page for lombok log annotations.
Is Lombok SLF4J vulnerable?
Does Lombok sl4j use Log4j?
Using Log4j2 Logging with Lombok. To use log4j2, exclude logback from classpath and include log4j2. Now you can use either @Slf4j (recommneded) or @Log4j2 at class to use log4j2 as underlying logging implementation. Drop me your questions related to using lombok for spring boot logging.
