【问题描述】:
我正在使用以下配置将 activemq 与 kafka 集成。我收到来自 activemq 的消息并将其转发给 kafka。但是,我注意到消息正在从 JMS 队列中出列,但消息不会发送到 kafka。
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jms="http://www.springframework.org/schema/integration/jms"

/ -->
</map>
</constructor-arg>
</bean>
</constructor-arg>
</bean>
</beans>
此外,如果 Kafka 出现任何问题,它甚至不会报告任何异常堆栈跟踪。
我错过了什么吗?

我不太了解 Spring,但在 Kafka 中,您需要配置 acks=all 以在代理存储您的消息时获得确认。如果 acks=0,您将不会收到提交消息成功或失败的确认。
