[SPRING] 로깅 뒤에서 봄

로깅 뒤에서 봄

내가 log4j2를 사용하고 나는 봄에서 로깅을 얻을 수 없습니다. 내 자신의 logger.debug (...); 작동하지만 System.out.println (...);과 같습니다.

나는 봄에 무슨 일이 일어 났는지 알고 싶다. 생성 된 빈을 표시하거나 오류 라인 400을 디버깅 ...

이 회의를 시도했지만 아무 일도 없었습니다.

해결법

1. ==============================

   1.문제가 해결되었습니다.이 오류는이 오류에서 비롯된 것 같습니다.

   문제가 해결되었습니다.이 오류는이 오류에서 비롯된 것 같습니다.

   SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
   SLF4J: Defaulting to no-operation (NOP) logger implementation
   SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
   

   나는 slf4j에서 log4j로 로그를 보내야한다. 왜냐하면 스프링은 로깅을 위해 slf4j를 사용한다. 그래서 log4j-slf4j-impl jar를 추가하고 마침내 작동한다 :-)

       <dependency> 
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-slf4j-impl</artifactId>
            <version>2.0-rc2</version>
        </dependency> 
   

   추신 : 왜냐하면 나는 log4j-jcl jar를 추가했기 때문에 Spring은 일반적인 로깅 대신 slf4j를 사용한다고 생각하지만 아무 일도 일어나지 않았습니다.

       <dependency> 
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-jcl</artifactId>
            <version>2.0-rc2</version>
        </dependency>
