多个侦听器,同一主题
从版本 3.0 开始,现在可以在同一主题上配置多个侦听器。 为此,您必须使用自定义主题命名来隔离重试主题。 最好通过一个例子来说明这一点:
@RetryableTopic(...
retryTopicSuffix = "-listener1", dltTopicSuffix = "-listener1-dlt",
topicSuffixingStrategy = TopicSuffixingStrategy.SUFFIX_WITH_INDEX_VALUE)
@KafkaListener(id = "listener1", groupId = "group1", topics = TWO_LISTENERS_TOPIC, ...)
void listen1(String message, @Header(KafkaHeaders.RECEIVED_TOPIC) String receivedTopic) {
...
}
@RetryableTopic(...
retryTopicSuffix = "-listener2", dltTopicSuffix = "-listener2-dlt",
topicSuffixingStrategy = TopicSuffixingStrategy.SUFFIX_WITH_INDEX_VALUE)
@KafkaListener(id = "listener2", groupId = "group2", topics = TWO_LISTENERS_TOPIC, ...)
void listen2(String message, @Header(KafkaHeaders.RECEIVED_TOPIC) String receivedTopic) {
...
}
这是可选的。
框架将为每个侦听器配置和使用一组单独的重试主题。topicSuffixingStrategy
