springboot2.1.3整合kafka后设置手动提交offset

主要代码：

@Bean
public KafkaListenerContainerFactory> kafkaListenerContainerFactory(ConsumerFactory consumerFactory) {
   ConcurrentKafkaListenerContainerFactory factory = new ConcurrentKafkaListenerContainerFactory<>();
   factory.setConsumerFactory(consumerFactory);
   factory.getContainerProperties().setPollTimeout(1500);
   //配置手动提交offset
   factory.getContainerProperties().setAckMode((ContainerProperties.AckMode.MANUAL));
   return factory;
}
