我是一名ActiveMQ初学者。我的主要看起来像这样:
public static void main(String[] args) throws Exception {
BrokerService broker = new BrokerService();
if(isProducer(args)){
broker.addConnector("tcp://localhost:8001");
broker.start();
// start producer...
}
else{
broker.addConnector("tcp://localhost:9000");
broker.addNetworkConnector("static:(tcp://localhost:8001)");
broker.start(); // Getting stuck here!!!
// start consumer
}
waitForever();
}
我启动此应用程序两次,一次是生产者,一次是消费者。 当我启动使用者时,它会卡在broker.start()行上。
我缺少什么?!

基本上你启动一次代理(将它嵌入到jvm中)。
BrokerService broker = new BrokerService();
broker.setUseJmx(true);
broker.addConnector("tcp://localhost:61616");
broker.start();
然后连接到代理(在使用者和生产者应用程序中都需要此代码):
url = "vm://localhost:61616" //if you are in same jvm
url2 = "tcp://localhost:61616" //if you are in diff jvm or other host
connectionFactory = new ActiveMQConnectionFactory(username,password,url);
connection = (ActiveMQConnection) connectionFactory.createConnection();
connection.start();
session = connection.createSession(transacted, ackMode);
然后设置消费者
Destination queue = session.createQueue("queuename");
MessageConsumer consumer = session.createConsumer(queue);
consumer.setMessageListener(new MessageConsumer());
设置制作人并发送消息
MessageProducer producer = session.createProducer(queue);
ObjectMessage objectMessage = session.createObjectMessage();
objectMessage.setObject(object);
producer.send(objectMessage);
