How to use Log4j2 in Spring Boot

[@rodolfosilva7478]

I have a question, do you know how can I set the log level by scope (warn, info, error) (prod, stage, develop)? thanks!

[@CodeJava]

When creating a logger in Java code, you can specify the category name: Logger logger = LoggerFactory.getLogger("prod"); Then in the configuration file: In log4j2 you can use any name of a logger, not just package name.

Do you have it for gradle? The console works, but it doesn't create the log file or it doesn't write to it, even when i create it.

[@CodeJava]

no, I don't have it for Gradle.

@germangonzalez7185 me too, If you have solved the problem, please help me

[@germangonzalez7185]

@@GiangLe-pv4gt My problem was how to leave out the the logging started. this is how you do it for gradle in build.gradle: configurations { all*.exclude group:'org.springframework.boot', module:'spring-boot-starter-logging' } also, be careful with the xml file with the appender ref and the root. However in the video this part is explained very well :)

I did same thing but I don't know why the fill is not creating on my project. if i do maven install then only I get the file, is there any solution for that.

Glad it helped.

There is no reason to use the SLF4J API to be "independent" of a logging implementation. You can use the Log4j 2 API for the same purpose. It does not require that the implementation be Log4j 2. The Log4j 2 API has more features - such as support for Lambda expressions and support for logging Messages instead of just Strings - than SLF4J.

[@CodeJava]

Awesome, thank you very much for your great insights

[@CodeJava]
