//指定消息监听器
consumer.setMessageListener(new MessageListener() {
//当监听的topic中存在消息,这个方法自动执行
public void onMessage(Message message) {
TextMessage textMessage = (TextMessage) message;
try {
System.out.println("消费者接收到消息:" + textMessage.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
});
while (true) {

}
}
acitveMQ持久化到文件时,生产者没有 connection.setClientID("client-1");但是为什么消费者需要设置conne connection.setClientID("client-1");?
