一次从java中的IBM MQ读取多条消息。

MQConnectionFactory connectionFactory = new MQConnectionFactory();
connectionFactory.setHostName("MQ服务器主机名");
connectionFactory.setPort(1414); // MQ服务器端口号
connectionFactory.setQueueManager("队列管理器名称");
connectionFactory.setChannel("通道名称");
connectionFactory.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP);

Connection connection = connectionFactory.createConnection();
connection.start();

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

Queue queue = session.createQueue("队列名称");

MessageConsumer consumer = session.createConsumer(queue);

while (true) {
    Message message = consumer.receive();
    if (message == null) {
        break;
    }
    // 处理接收到的消息
    // ...
}

consumer.close();
session.close();
connection.close();
