java - log4j-over-slf4j.jar 和 slf4j-log4j12.jar 冲突...但我没有 slf4j-log4j12.jar

标签 java log4j apache-kafka apache-storm maven-assembly-plugin

我在尝试集成kafka、storm和druid时遇到了这个问题。

它们对应的版本是:

kafka_2.11-0.8.2.2
druid-0.9.1.1
apache-storm-0.10.1

log4j-over-slf4j.jar and slf4j-log4j12.jar conflitct... but i don't have log4j-over-slf4j 这个问题几乎与我的问题相似，只是即使我排除了 slf4j-log4j12.jar，我也收到了此错误。这是与 KafkaSpout(storm.kafka.KafkaSpout) 对应的 Storm 日志中的错误的样子:

2016-08-02 14:54:50.446 STDIO [ERROR] SLF4J: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.

这是我的 mvn dependency:tree 输出

我在我的 pom.xml 中排除了 kafka 的 slf4j-log4j12.jar:

<dependency>
    <groupId>org.apache.storm</groupId>
    <artifactId>storm-kafka</artifactId>
    <version>0.10.1</version>
</dependency>
<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.11</artifactId>
    <version>0.8.2.2</version>
    <exclusions>
        <exclusion>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
        </exclusion>
        <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>

    </exclusions>
</dependency>

我使用 maven-assemble-plugin 构建了一个分发箱，供storm-nimbus 解析:

<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
    <descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>                    
<archive>
<manifest>                                   
    <mainClass>com.cloud.storm.topology.TopologyService</mainClass>
</manifest>
</archive>
</configuration>

</plugin>

这个问题的原因是什么？如果我想排除 slf4j-log4j12 并保留 log4j-over-slf4j，我该怎么办？

提前致谢。

最佳答案

查找您的拓扑 jar 中是否有 org.slf4j.impl.Log4jLoggerFactory 类。

例如，activemq-all jar有这个类，并且会导致检测到slf4j-log4j12.jar。

关于java - log4j-over-slf4j.jar 和 slf4j-log4j12.jar 冲突...但我没有 slf4j-log4j12.jar，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38715380/
