错误表现：

SLF4J: Class path contains multiple SLF4J bindings.

解决方案：

 

可以转到pom.xml，打开Dependency Hierarchy并找到slf4j条目。除了通过右键单击“exclude maven artifact”排除其余条目。

运行mvn dependency:tree并搜索哪些依赖项具有slf4j您不想要的实现，然后使用依赖项排除将其排除，例如：

        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>slf4j-log4j12</artifactId>
                    <groupId>org.slf4j</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>com.github.sgroschupf</groupId>
            <artifactId>zkclient</artifactId>
        </dependency>
        <!-- 配置对ActiveMQ客户端的依赖jar包 -->
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
        </dependency>
        <dependency>
            <groupId>com.taotao</groupId>
            <artifactId>taotao-common</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <artifactId>slf4j-log4j12</artifactId>
                    <groupId>org.slf4j</groupId>
                </exclusion>
            </exclusions>
        </dependency>
