ActiveMQ 客户端问题：ClassNotFoundException org.apache.logging.log4j.spi.AbstractLoggerAdapter

Question

我有一个小型 ActiveMQ 客户端，它应该只是连接到 AMQ 服务、创建队列并发送消息。我收到以下错误消息：

Failed to instantiate SLF4J LoggerFactory
Reported exception:
java.lang.NoClassDefFoundError: org/apache/logging/log4j/spi/AbstractLoggerAdapter
  at java.lang.ClassLoader.defineClassl(Native Method)
  ...

以下罐子在我的 classpath 上：

log4j-1.2-api-2.6.2.jar
log4j-core-2.6.2.jar
log4j-slf4j-impl-2.6.2.jar

activemq-broker-5.13.3.jar
activemq-client-5.13.3.jar
activemq-console-5.13.3.jar
activemq-jaas-5.13.3.jar
activemq-kahadb-store-5.13.3.jar
activemq-openwire-legacy-5.13.3.jar
activemq-protobuf-1.1.jar
activemq-spring-5.13.3.jar
activemq-web-5.13.3.jar
geronimo-j2ee-management_1.1_spec-1.0.1.jar
geronimo-jms_1.1_spec-1.1.1.jar
geronimo-jta_1.0.1B_spec-1.0.1.jar
hawtbuf-1.11.jar
jcl-over-slf4j-1.7.13.jar
slf4j-api-1.7.13.jar

如果我去掉前三个库，我会得到错误 Failed to load class “org.slf4j.impl.StaticLoggerBinder”

我试过搜索，但我不能说我找到了到目前为止有用的东西。

Answer 1

您需要将 log4j-api-2.6.2.jar 添加到类路径中。

Answer 2

我有完全相同的错误。我将 org.apache.logging.log4j:log4j-slf4j-impl:2.12.1 替换为 org.slf4j:slf4j-simple:2.0.0-alpha1。它帮助了我。
