java - JBoss 多个 SLF4J 绑定(bind)错误

Question

我正在使用 JBoss 6 并在尝试运行我的应用程序时收到多个版本错误:

ERROR [STDERR] SLF4J: Class path contains multiple SLF4J bindings.

ERROR [STDERR] SLF4J: Found binding in [vfs:/C:/jboss-6.0.0.Final/common/lib/slf4j-jboss-logmanager.jar/org/slf4j/impl/StaticLoggerBinder.class]

ERROR [STDERR] SLF4J: Found binding in [vfs:/C:/jboss-6.0.0.Final/server/default/deploy/newsroom-integration-persistence-service.war/WEB-INF/lib/slf4j-log4j12-1.6.1.jar/org/slf4j/impl/StaticLoggerBinder.class]

我的应用程序在 pom 中声明了 slf4j-log4j12 但没有声明 slf4j-jboss-logmanager 所以不知道为什么要尝试使用它。这是 pom:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>${org.slf4j-version}</version>
    <scope>runtime</scope>
</dependency>

关于如何解决这个问题的任何想法？即使在 jboss-logging.xml 中设置的级别名称设置为 INFO，它似乎也会导致 'DEBUG' 级别的错误被写入控制台!

无论您在pom.xml 中声明什么，JBoss 都会加载其公共(public)类路径中的内容。如果您更喜欢使用 log4j 绑定(bind)，那么您必须删除 C:/jboss-6.0.0.Final/common/lib/slf4j-jboss-logmanager.jar .这是Alfresco推荐的方法.引用:

You may see the following errors during the startup:

2011-10-12 10:47:21,505 ERROR [STDERR] (main) SLF4J: Class path contains multiple SLF4J bindings.

2011-10-12 10:47:21,505 ERROR [STDERR] (main) SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

To avoid these errors, remove the /common/lib/slf4j-jboss-logging.jar file.
