[spring-boot] SpringBoot에서 Logback 비활성화

Program / 글쓴이

Springboot는 Tomcat과 함께 Logback을 사용하도록 자동 구성됩니다. 이것을 비활성화하고 클래스 경로에서 제공하는 것을 사용하고 싶습니다.

아래 오류 메시지입니다.

LoggerFactory는 Logback LoggerContext가 아니지만 Logback은 클래스 경로에 있습니다. Logback 또는 경쟁 구현 (class org.slf4j.impl.SimpleLoggerFactory)을 제거하십시오. [org.slf4j.impl.SimpleLoggerFactory] 클래스의 객체는 ch.qos.logback.classic.LoggerContext 클래스의 인스턴스 여야합니다.

spring-boot-starter 및 spring-boot-starter-web 모두에 제외를 추가하여 충돌을 해결하십시오.

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

답변

Gradle에 더 좋고 더 일반적인 솔루션을 추가하려면 (모든 인스턴스가 제외됩니다) :

configurations {
    all*.exclude module : 'spring-boot-starter-logging'
}

에서 https://docs.gradle.org/current/userguide/dependency_management.html

답변

Gradle에 솔루션을 추가하려면.

dependencies {
    compile ('org.springframework.boot:spring-boot-starter') {
        exclude module : 'spring-boot-starter-logging'
    }
    compile ('org.springframework.boot:spring-boot-starter-web') {
        exclude module : 'spring-boot-starter-logging'
    }
}

답변

전체 spring-boot-starter-logging모듈 을 제외 할 필요가 없다는 것을 알았습니다 . 필요한 것은 org.slf4j:slf4j-log4j12모듈 을 제외하는 것 입니다.

이것을 Gradle 빌드 파일에 추가하면 문제가 해결됩니다.

configurations {
    runtime.exclude group: "org.slf4j", module: "slf4j-log4j12"
    compile.exclude group: "org.slf4j", module: "slf4j-log4j12"
}

자세한 내용은 다른 StackOverflow 답변 을 참조하십시오.

답변

나는 내 문제를 해결하기 위해 이것을 좋아한다. 

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
    </exclusions>
</dependency>

답변

Gradle의 경우

이 솔루션은 http://www.idanfridman.com/how-to-exclude-libraries-from-dependcies-using-gradle/ 에서 볼 수 있습니다 .

추가 exclude가 필요합니다 configurations.

configurations {
    providedRuntime
    compile.exclude(group: 'ch.qos.logback')
}

답변

pom.xml에서 spring-boot-starter-test를 찾아 다음과 같이 수정합니다.

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

다음과 같은 오류가 수정되었습니다.

_Caused by: java.lang.IllegalArgumentException:_ **LoggerFactory** is not a **Logback LoggerContext** but *Logback* is on the classpath.

Either remove **Logback** or the competing implementation

(_class org.apache.logging.slf4j.Log4jLoggerFactory_
loaded from file:

**${M2_HOME}/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.6.2/log4j-slf4j-impl-2.6.2.jar**).

If you are using WebLogic you will need to add **'org.slf4j'** to prefer-application-packages in WEB-INF/weblogic.xml: **org.apache.logging.slf4j.Log4jLoggerFactory**
