Apache Camel ™ is a versatile open-source integration framework based on known Enterprise Integration Patterns.

連接activemq收發消息

public class TemporaryConsumer {

    public static void main(String[] args) throws Exception {
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");

        CamelContext context = new DefaultCamelContext();
        context.addComponent("jms", JmsComponent.jmsComponent(connectionFactory));
        context.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("file:E:\\test").convertBodyTo(String.class).to("jms:queue:firstQueue");
                from("jms:queue:firstQueue").log("${body}").to("file:E:\\test\\destination");
            }
        });

        context.start();
        Thread.sleep(Integer.MAX_VALUE);
    }
}

將一個xml文件放入test文件夾下，發送到firstQueue，再從firstQueue中拿到消息放入destination文件夾下。
