[Spring Boot] 로깅 - 커스터마이징

1. 커스터마이징한 로그 설정 파일 사용하기

• Logback : logback-spring.xml
• Log4J2 : log4j2-spring.xml
• JUL : logging-properties (추천x)
• Logback extensions
  - Profile-specific Configuartion (프로파일 별 로그레벨 지정) : <springProfile name="프로파일"> 
  - Environment Properties 들도 사용 가능 : <springProperty>
  
  

logback 설정 파일 안에서 Profile이나 Environment variable을 사용할 수 있으려면
logback.xml이 아닌 logback-spring.xml을 사용해야 함 
(logback.xml은 너무 일찍 로딩이 되기 때문에 사용 불가)

 

 

# logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml"/>
    <include resource="org/springframework/boot/logging/logback/console-appender.xml" />
    <root level="INFO">
        <appender-ref ref="CONSOLE" />
    </root>
    <logger name="kvp.hyelin.springboot" level="DEBUG"/>
</configuration>

 

 

# <springProfile>

 

<springProfile name="staging">
    <!-- configuration to be enabled when the "staging" profile is active -->
</springProfile>

<springProfile name="dev | staging">
    <!-- configuration to be enabled when the "dev" or "staging" profiles are active -->
</springProfile>

<springProfile name="!production">
    <!-- configuration to be enabled when the "production" profile is not active -->
</springProfile>

 

 

 

 

 

 

 

 

2. 로거를 Log4j2로 변경하기

 

spring-boot-starter 내에 logging 제외시키고

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter</artifactId>
   <exclusions>
      <exclusion>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-starter-logging</artifactId>
      </exclusion>
   </exclusions>
</dependency>

 

log4j2 의존성 추가

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>
