当从jms队列向处理器发送数据时，我正面临上述异常，任何人都可以帮助解决此问题。 任何人都可以建议如何在apache camel java RDSL中实现jms Queue。 任何指针都对我有用..
谢谢..
答案 0 :(得分：0)
消息处理器是一个字符串，例如
from("test-jms:queue:test.queue").to("messageProcessor");
这使得Camel假定它是一个具有该名称的组件而不是它，因此将其更改为
from("test-jms:queue:test.queue").process(new Processor() ... );
并内联一个处理器，您可以在其中对消息执行某些操作，或者如果您只是想进行快速测试，则使用日志端点
from("test-jms:queue:test.queue").to("log:hello");
还要注意start上的CamelContext方法没有阻止。请参阅此常见问题解答：http://camel.apache.org/running-camel-standalone-and-have-it-keep-running.html
