[英]NoClassDefFound - org/apache/kafka/clients/producer/KafkaProducer
我有一个ear的文件，里面ear文件我也有war文件。 它基于Spring 2.5.6和JDK 1.6
现在我想发布一些消息给kafka，包括war/web-inf/lib kafka-clients-1.0.0
但它得到NoClassDefFoundError org/apache/kafka/clients/producer/KafkaProducer 。
NoClassDefFoundError通常在您的项目具有冲突依赖性时发生，例如Spring框架的第3和第4版本。 检查您的依赖项及其可传递的依赖项。
这只是意味着您在类路径中未找到要运行的类。 解决方案：您需要将包含此类的类或.jar文件添加到java类路径中。
