Question

我希望从兔子队列中侦听，处理并将消息发布到另一个兔子队列。我不是在和春天一起工作。消息在此配置中重复。

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");
        }
    });

我也试过这个：

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();
}

工作队列以四条消息开始，但消息重新排队：

561消息ID-host-1510600494291-0-2
  566消息ID-host-1510600494291-0-4

Answer 1

在不知道结果的情况下查看您的代码，我注意到当您尝试使用注册表中的bean时，您错过了您错过了“＃”。

使用注册表中的内容时需要做的是

public static void main(String[] args) throws Exception {
DefaultCamelContext context = new DefaultCamelContext();

ConnectionFactory connectionFactory = new ConnectionFactory();
SimpleRegistry registry = new SimpleRegistry();
String beanNameWorker = "connectionFactoryWorker";
String beanNameProcessed = "connectionFactoryProcessed";
registry.put(beanNameWorker, connectionFactory);
registry.put(beanNameProcessed, connectionFactory);
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");
    }
});

}

顺便说一下，实际结果是什么？你有什么错误？

我相信我可能在另一个问题中找到了答案

Infinite loop in Camel - Rabbit MQ

显然设置BridgeEnpoint = false选项会停止此操作。如果不指定此项，则EXCHANGE_NAME和ROUTING_KEY标头将从收到的消息中获取，该消息将覆盖您在＆＃34;中指定的任何内容。组态。例如... rabbitmq://localhost/B?connectionFactory=connectionFactoryProcessed&autoDelete=false&queue=processed&BridgeEndpoint=false

如何为相同的Camel RouteBuilder配置方法设置两个RabbitMQ连接
