KafkaBindingRebalanceListener
应用程序可能希望在分配分区时寻找任意偏移的主题/分区，或对消费者执行其他作。
从2.1版本开始，如果你提供一个KafkaBindingRebalanceListener在应用环境中，它将被连接到所有 Kafka 消费者绑定中。
public interface KafkaBindingRebalanceListener {
/**
* Invoked by the container before any pending offsets are committed.
* @param bindingName the name of the binding.
* @param consumer the consumer.
* @param partitions the partitions.
*/
default void onPartitionsRevokedBeforeCommit(String bindingName, Consumer<?, ?> consumer,
Collection<TopicPartition> partitions) {
}
/**
* Invoked by the container after any pending offsets are committed.
* @param bindingName the name of the binding.
* @param consumer the consumer.
* @param partitions the partitions.
*/
default void onPartitionsRevokedAfterCommit(String bindingName, Consumer<?, ?> consumer, Collection<TopicPartition> partitions) {
}
/**
* Invoked when partitions are initially assigned or after a rebalance.
* Applications might only want to perform seek operations on an initial assignment.
* @param bindingName the name of the binding.
* @param consumer the consumer.
* @param partitions the partitions.
* @param initial true if this is the initial assignment.
*/
default void onPartitionsAssigned(String bindingName, Consumer<?, ?> consumer, Collection<TopicPartition> partitions,
boolean initial) {
}
}你不能设置resetOffsets消费者财产true当你提供一个重新平衡的听众时。
