SLF4J:类路径包含多个SLF4J绑定

我得到如下错误。似乎有多个日志框架绑定到slf4j。不知道如何解决这个问题。任何帮助都非常感激。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/admin/.m2/repository/org/slf4j/slf4j-log4j12/1.6.4/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/admin/.m2/repository/org/slf4j/slf4j-log4j12/1.6.1/slf4j-log4j12-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Sbt版:

添加排除(“org。Slf4j "， " Slf4j -log4j12")传递到包含Slf4j -log4j12的依赖项。例如，当使用Log4j 2.6使用Spark时:

libraryDependencies ++= Seq(
  // One SLF4J implementation (log4j-slf4j-impl) is here:
  "org.apache.logging.log4j" % "log4j-api" % "2.6.1",
  "org.apache.logging.log4j" % "log4j-core" % "2.6.1",
  "org.apache.logging.log4j" % "log4j-slf4j-impl" % "2.6.1",
  // The other implementation (slf4j-log4j12) would be transitively
  // included by Spark. Prevent that with exclude().
  "org.apache.spark" %% "spark-core" % "1.5.1" exclude("org.slf4j", "slf4j-log4j12")
)

其他回答

通过在(pom.xml的)依赖项中添加以下导致冲突的排除来解决。

<exclusions>
    <exclusion>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-log4j12</artifactId>
    </exclusion>
</exclusions>

只使用所需的依赖项，而不是全部:)))。对于我来说，对于正常的日志记录过程，您需要这个依赖项来排除pom.xml中的其他依赖项

<dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.5</version>
    </dependency>

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.1.8</version>
    </dependency>

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-core</artifactId>
        <version>1.1.8</version>
    </dependency>

我也有同样的问题。在我的pom.xml中，两者都有

 <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>1.7.28</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>2.2.1.RELEASE</version>
    </dependency>

当我删除spring-boot-starter-web依赖时，问题就解决了。

Gradle版;

configurations.all {
    exclude module: 'slf4j-log4j12'
}

对于那些寻找spring-boot类型依赖的解决方案的人来说，Gradle的魔法咒语是这样的:

configurations.all {
    exclude group: 'ch.qos.logback', module: 'logback-classic'
}

在你的构建中。Gradle在顶层(不是在依赖块内)。

在网上找到的所有其他解决方案(包括这里建议排除slf4j模块的解决方案)对我都不起作用。

这就是我的身材。gradle(片段):


// Removes the annoying warning about the multiple SLF4J implementations:
//    SLF4J: Class path contains multiple SLF4J bindings.
configurations.all {
    exclude group: 'ch.qos.logback', module: 'logback-classic'
}

dependencies {
    annotationProcessor "org.springframework.boot:spring-boot-configuration-processor"

    implementation ('org.springframework.boot:spring-boot-starter-actuator')
    implementation ('org.springframework.boot:spring-boot-starter-data-mongodb-reactive')
    implementation ('org.springframework.boot:spring-boot-starter-webflux')

    annotationProcessor "org.projectlombok:lombok:${lombokVersion}"
    compileOnly "org.projectlombok:lombok:${lombokVersion}"

    // Removes the annoying warning:
    // warning: unknown enum constant When.MAYBE
    //  reason: class file for javax.annotation.meta.When not found
    // See: https://stackoverflow.com/questions/29805622/could-not-find-or-load-main-class-org-gradle-wrapper-gradlewrappermain/31622432
    implementation group: 'com.google.code.findbugs', name: 'jsr305', version: '3.0.2'

    // other stuff...

YMMV
