我正在使用 Camel 版本 3.1，并尝试使用 AMQP 组件 和 Spring boot 将消息从一个 ActiveMQ 服务器发送到另一个服务器。发送消息后，在目标 ActiveMQ 控制台，消息详细信息具有以下内容。
Sp�ASr�)�x-opt-jms-destQ�x-opt-jms-msg-typeQSs�^

我的实际消息是
1:"test message"下面是 Spring Boot 代码示例

解决方案：我们需要在ActiveMQ配置文件中添加
transport.transformer="jms"<transportConnector name="amqp" uri="amqp://localhost:5672?**transport.transformer=jms**"/>这实际上会让 ActiveMQ 正确映射传入的 JMS 消息标头。
'transport.transformer=native'您正在使用 ActiveMQ 和 AMQP 协议。您是否还为此协议配置了代理？
例如传输连接器：
<transportConnector name="amqp" uri="amqp://0.0.0.0:5672"/>
说实话我不知道当您使用普通的ActiveMQ代理（默认协议是OpenWire）并向其发送AMQP消息时会发生什么。
在您的情况下，Camel 似乎能够正确地在队列中生成和使用消息。这并不奇怪，因为生产者和消费者都配置为 AMQP。代理只存储消息。
另一方面，您写道 Springs JmsListener 弄乱了消费消息。可能是因为它不需要 AMQP 消息，并且您尝试接收 JMS 消息（TextMessage、ByteMessage 等）。
您可以尝试简单地接收一个
Message<?>
