异常信息如下：

Exception in thread "main" java.lang.IllegalStateException: Subscription to topics, partitions and pattern are mutually exclusive
	at org.apache.kafka.clients.consumer.internals.SubscriptionState.setSubscriptionType(SubscriptionState.java:104)
	at org.apache.kafka.clients.consumer.internals.SubscriptionState.assignFromUser(SubscriptionState.java:157)
	at org.apache.kafka.clients.consumer.KafkaConsumer.assign(KafkaConsumer.java:1064)

从异常信息可以看出订阅的主题和分区模式有冲突，查看 Consumer 代码，的确是写错了：

去掉一个即可。
