## 执行消费的类 ##

@Service
    public class myMsgListener implements MessageListerner<String,String> {
    
        @Override
        public void omMessage(ConsumerRecord<String, String> consumerRecord) {
             try {
                 自定义类  = JSON.parseObject(consumerRecord.value(), 自定义类.class);
                 // 业务逻辑处理 
                 ......
             } catch(Exception e) {
    
             }
            
        }
