如何为同一Camel RouteBuilder配置方法设置两个RabbitMQ连接 [英] How to set two RabbitMQ connections for the same Camel RouteBuilder configure method

问题描述

我想从兔子队列监听，处理并将消息发布到另一个兔子队列.我不和春天打交道.邮件在此配置中重复.

I want listen FROM rabbit queue, process, and post message TO another rabbit queue. I'm not working with spring. The messages are duplicated in this configuration.

这是一个简短的代码:

context.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("rabbitmq://localhost/B?autoDelete=false&queue=worker&threadPoolSize=1&autoAck=false").
                    log(LoggingLevel.INFO, "Message ${id}").
                    to("rabbitmq://localhost/B?autoDelete=false&queue=processed");
        }
    });

我也尝试过:

public static void main(String[] args) throws Exception {
    org.apache.camel.impl.DefaultCamelContext context = new DefaultCamelContext();

    com.rabbitmq.client.ConnectionFactory connectionFactoryWorker = new ConnectionFactory();
    com.rabbitmq.client.ConnectionFactory connectionFactoryProcessed = new ConnectionFactory();
    org.apache.camel.impl.SimpleRegistry registry = new SimpleRegistry();
    String camelBeanNameWorker = "connectionFactoryWorker";
    String camelBeanNameProcessed = "connectionFactoryProcessed";
    registry.put(camelBeanNameWorker, connectionFactoryWorker);
    registry.put(camelBeanNameProcessed, connectionFactoryProcessed);
    context.setRegistry(registry);

    context.addRoutes(new RouteBuilder() {
        @Override
        public void configure() throws Exception {
            from("rabbitmq://localhost/B?connectionFactory=connectionFactoryWorker&autoDelete=false&queue=worker&threadPoolSize=1&autoAck=false").
                    log(LoggingLevel.INFO, "Message ${id}").
                    to("rabbitmq://localhost/B?connectionFactory=connectionFactoryProcessed&autoDelete=false&queue=processed");
        }
    });

    context.start();
    Thread.sleep(10000l);
    context.stop();
}

工人队列从四个消息开始，但是消息被重新排队:

Worker queue start in four messages, but Messages are re-queued:

566消息ID-host-1510600494291-0-4

推荐答案

我相信我可能在另一个问题中找到了您的答案

I believe I may have found your answer in another question

Camel中的无限循环-Rabbit MQ

显然，设置BridgeEnpoint = false选项将停止此操作.如果未指定此内容，则从接收到的消息中获取EXCHANGE_NAME和ROUTING_KEY标头，以覆盖您可能在至"配置中指定的内容.例如... rabbitmq://localhost/B?connectionFactory=connectionFactoryProcessed&autoDelete=false&queue=processed&BridgeEndpoint=false

Apparently setting BridgeEnpoint=false option stops this. Without specifying this the EXCHANGE_NAME and ROUTING_KEY headers are taken from the received message overriding whatever you might have specified in the "to" configuration. For example... rabbitmq://localhost/B?connectionFactory=connectionFactoryProcessed&autoDelete=false&queue=processed&BridgeEndpoint=false
