下面是我在 Apache Camel 反应流解决方案中尝试跨 JVM 将发布者连接到订阅者（骆驼路由的代码如下所示）
为了使通信能够跨越 JVM，似乎需要一个“代理”服务器。因此，我已经实现了 Artemis 代理并相应地修改了 application.properties 文件（根据我对如何执行此操作的最佳理解）。
此外，为了缩小焦点，选择使用 smallrye-ampq 连接器。
问题：
订阅者应该接收并记录字符串值（来自正文）：
-
-
-
:blahblahblah
:blahblahblah
:blahblahblah
-
-
-
--相反，它正在记录值，如下所示：
-
-
-
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-289]
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-292]
:Exchange[ID-LAPTOP-4LR4PMVQ-1576639597494-0-295]
-
-
-
问题：
为什么发布者发送的有效负载没有到达订阅者，我可以修改哪些代码/配置来修复它？
提前谢谢您的帮助！
