java - SLF4J:类路径包含多个SLF4J绑定(bind)；排除 slf4j

Question

我正在尝试使用 OpenIMAJ 加载视频。它确实显示视频，但总是向我显示此错误:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/MaryLu/.m2/repository/ch/qos/logback/logback-classic/1.0.0/logback-classic-1.0.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/MaryLu/.m2/repository/org/slf4j/slf4j-log4j12/1.7.2/slf4j-log4j12-1.7.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.selector.DefaultContextSelector]
16/04/24 20:39:57 INFO xuggle.XuggleVideo: URL file:/F:/workspaceMaven/keyboardcat.flv could not be opened by ffmpeg. Trying to open a stream to the URL instead.
20:39:57.984 [main] DEBUG com.xuggle.xuggler - Could not open output url: file:/F:/workspaceMaven/keyboardcat.flv (../../../../../../../csrc/com/xuggle/xuggler/Container.cpp:436)

我已经检查了类似的问题，但我没有设法解决问题。如果我理解，我需要在 POM.xml 中的某个位置排除 slf4j，但我真的不知道哪个依赖项。

答案已在您的日志文件中给出。按照教程进行操作。

如Wouter声明

运行 mvn dependency:tree 并搜索哪个依赖项具有您不想要的 slf4j 实现，然后使用依赖项排除来排除它们，例如:

<dependency>
    <groupId>org.someexternallib</groupId>
    <artifactId>someexternallibartifact</artifactId>
    <version>...</version>

    <exclusions>
       <exclusion> 
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-log4j12</artifactId>
       </exclusion>
       <exclusion> 
          <groupId>log4j</groupId>
          <artifactId>log4j</artifactId>
      </exclusion>
    </exclusions> 
</dependency>
