KafkaBindingRebalanceListener
应用程序可能希望在初始分配分区时寻找任意偏移量的主题/分区，或者对使用者执行其他操作。
从版本 2.1 开始，如果在应用程序上下文中提供一个单例 KafkaBindingRebalanceListener bean，则将其注入所有 Kafka 消费器绑定中。
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) {
}
}不能将 resetOffsets 消费器属性设置为 true，同时提供平衡侦听器。
