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：

\n\n

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

\n\n

我的上有以下罐子classpath：

\n\n

log4j-1.2-api-2.6.2.jar\nlog4j-core-2.6.2.jar\nlog4j-slf4j-impl-2.6.2.jar\n\nactivemq-broker-5.13.3.jar\nactivemq-client-5.13.3.jar\nactivemq-console-5.13.3.jar\nactivemq-jaas-5.13.3.jar\nactivemq-kahadb-store-5.13.3.jar\nactivemq-openwire-legacy-5.13.3.jar\nactivemq-protobuf-1.1.jar\nactivemq-spring-5.13.3.jar\nactivemq-web-5.13.3.jar\ngeronimo-j2ee-management_1.1_spec-1.0.1.jar\ngeronimo-jms_1.1_spec-1.1.1.jar\ngeronimo-jta_1.0.1B_spec-1.0.1.jar\nhawtbuf-1.11.jar\njcl-over-slf4j-1.7.13.jar\nslf4j-api-1.7.13.jar\n

如果我去掉前三个库，我会收到错误Failed to load class \xe2\x80\x9corg.slf4j.impl.StaticLoggerBinder\xe2\x80\x9d

我尝试过搜索，但我不能说我找到了迄今为​​止有效的任何东西。

您需要将 log4j-api-2.6.2.jar 添加到类路径中。
