Question

我在Map中有消息 - key作为队列名称，值作为消息列表。每当我向队列服务器发布多个消息时，就会抛出异常，因为用户已达到允许的最大登录次数。

将消息发布到1个队列时

。下面是执行的代码：

public class MessageManager {

public static void publish(String exchange, HashMap<String, List<String>> queueNameWithMessages) throws IOException {
    ...
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost(Constants.HOST_NAME);
    factory.setUsername(Constants.USER_NAME);
    factory.setPassword(Constants.PASSWORD);
    factory.setPort(Constants.PORT);
    Connection connection = factory.newConnection();
    Channel ch = connection.createChannel();
    Channel ch1 =  connection.createChannel();
    try {
        for(Entry<String, List<String>> entry : queueNameWithMessages) {
            String routingKey = entry.getKey();
            for(String  messageToBeSent : entry.value()) {
                ch.basicPublish(exchange, routingKey, true, MessageProperties.PERSISTENT_BASIC,  messageToBeSent.getValue().getBytes());
            }
            ExecutorService threadExecutor = Executors.newFixedThreadPool(5);
            String responseKey = props.getProperty(routingKey);
            if(!CLAMUtility.workingListnerToRespnseQueue.contains(responseKey)) {
                Worker fast = new Worker(0, threadExecutor, ch1,responseKey, routingKey);
                CLAMUtility.workingListnerToRespnseQueue.add(responseKey);
            }
        }
        ch.close();
        System.out.println("Message published successfully!\n \n");
    } catch (Exception e) {
        e.printStackTrace();
    } 
}

}

我们发现此问题与Rabbit MQ无关。消息使用者系统具有一些与用户交互相关的限制，这些限制未得到妥

谢谢！
