IBM MQ获取带有法语符号的消息

Question

如何解码带有法语符号的消息？MQ中消息的示例：

  "name":" ĄĆĘŁŃÓŚŹŻąćęłńóśźżƵƶÁáÂâÃãÀàÇçÉéÊêÍíÓóÔôÕõÚúÀÉÈÍÏÓÒÚÜÇ",
  "id":"2463"

当我从MQ收到消息时，有：

"name":" ",
"id":"2463"

归档的“名称”看起来如下：

我使用的代码：

    public static String getMessage() throws JMSException {
            String message = null;
            try {
                MQQueueConnectionFactory cf = new MQQueueConnectionFactory();
                MQGetMessageOptions gmo = new MQGetMessageOptions();
                gmo.options = MQGMO_ALL_MSGS_AVAILABLE | MQGMO_WAIT | MQGMO_PROPERTIES_AS_Q_DEF | MQGMO_FAIL_IF_QUIESCING | MQOO_INPUT_AS_Q_DEF | MQGMO_SYNCPOINT
                         | MQC.MQGMO_CONVERT;;
                cf.setHostName(HOST);
                cf.setChannel(CHANNEL);
                cf.setPort(PORT);
                cf.setQueueManager(QMN);
                cf.setTransportType(WMQConstants.WMQ_CM_CLIENT);


                MQQueueConnection connection = (MQQueueConnection) cf.createQueueConnection();
                MQQueueSession session = (MQQueueSession) connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
                MQQueue queue = (MQQueue) session.createQueue(QUEUE_NAME);


                MQQueueReceiver receiver = (MQQueueReceiver) session.createReceiver(queue);


                connection.start();
                TextMessage receivedMessage = (TextMessage) receiver.receive();
                            byte[] bytes = receivedMessage.getText().getBytes("UTF-8");
                String s = new String(bytes, "UTF-8");

如果消息是TextMessage的实例，则它将包含符合UTF-16的字符串，而不是字节数组。

但是，您应该添加一些保护逻辑以确保：

        Message receivedMessage = receiver.receive();
        if (receivedMessage instanceof TextMessage) {
            TextMessage textMessage = (TextMessage) receivedMessage;
            try {
                String text = textMessage.getText();
                ...
            } catch (JMSException jmsex) {
                ...
            }
        } else {
        // Not a TextMessage, maybe its a JMSBytesMessage, let's check 
           ...
        }
