Kafka使用报错Subscription to topics, partitions and pattern are mutually exclusive

Exception in thread "main" java.lang.IllegalStateException: Subscription to topics, partitions and pattern are mutually exclusive

Kafka手动分区分配assign(Collection)不能和自动分区分配subscribe(Collection, ConsumerRebalanceListener)一起使用

如果使用自动分区分配，那就不要使用手动分区分配，反之亦然，两者不可同时使用，使用一种方法，就注释掉另一种方法。
如使用手动分区分配，那么注释掉自动分区分配。

//   consumer.subscribe(Collections.singleton("tp_demo_01"));

final Set assignment1 = consumer.assignment();
for (TopicPartition partition : assignment1) {
    System.out.println(partition);
}
