我有一个小型服务器路由，它从queue.in 获取消息并放入queue.out。
当我输入一条消息时queue.in，服务器无限循环运行。我想知道我在配置方面缺少什么。这看起来是一条非常简单的路线。
小服务器路由：
<camelContext id="camel-server" xmlns="http://camel.apache.org/schema/spring">
<jmxAgent disabled="false" onlyRegisterProcessorWithCustomId="false"
createConnector="true" usePlatformMBeanServer="true"
registerNewRoutes="true" statisticsLevel="All" includeHostName="false"
mask="false" id="agent" />
<endpoint id="queue.in" uri="${queue.url.input_queue}" />
<endpoint id="queue.out" uri="${queue.url.output_queue}" />
<route id="rabbitRoute">
<from uri="ref:queue.in" />
<bean ref="multiplier" /><!-- a simple bean that appends "BeanHello" to input msg-->
<to uri="ref:queue.out" />
</route>
</camelContext>
rabbitmq队列属性：
queue.url.input_queue=rabbitmq://localhost:5672/ex1?queue=input_queue&routingKey=input_queue&connectionFactory=#customConnectionFactory&autoDelete=false&autoAck=true
queue.url.output_queue=rabbitmq://localhost:5672/ex1?queue=output_queue&routingKey=output_queue&connectionFactory=#customConnectionFactory&autoDelete=false&autoAck=true
日志文件的片段 - 请参阅日志末尾的递归部分：字符串“BeanHello”被多次添加，这意味着消息将一次又一次地进入queue.in，而不是进入queue.out。
