我是kafka和springboot的新手,并试图将kafka和弹性搜索集成到我的springboot应用程序中。
当我尝试运行springboot应用程序时,出现以下错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'kafkaListenerContainerFactory' defined in class path resource [org/springframework/boot/autoconfigure/kafka/KafkaAnnotationDrivenConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory]: Factory method 'kafkaListenerContainerFactory' threw exception; nested exception is java.lang.NoSuchMethodError:org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory.getContainerProperties()Lorg/springframework/kafka/listener/config/ContainerProperties;

答案 0 :(得分:0)
您应该检查完整的错误日志(stacktrace)。在我的情况下,问题是由下面的 java.io.FileNotFoundException
引起的。
通常,您会在堆栈跟踪末尾找到“真正的”问题。
