如何序列化JMS消息？

Question

我正在尝试序列化JMS消息，以便我可以将其转换为BLOB并将其保存到SQL数据库中。

我的第一次天真尝试使用了一个Serializable类，它将其作为一个字段，如下所示：

private static class SerializableWrapper implements Serializable{
    Message message;
    private SerializableWrapper(Message message){
        this.message = message;
    }

    private Message getMessage() {
        return message;
    }

    private void setMessage(Message message) {
        this.message = message;
    }
    private void writeObject(java.io.ObjectOutputStream out)
            throws IOException{
        out.writeObject(getMessage());
    }

    private void readObject(java.io.ObjectInputStream in)
            throws IOException, ClassNotFoundException {
        setMessage((Message) in.readObject());
    }
}

这不起作用，并继续为NotSerializableException抛出JMSTextMessage。我不确定是否有其他第三方库可能有助于序列化这一点，但我的任务要求是 不 根本没有第三方依赖。

有没有好的/合理的方法可以做到这一点而不需要其他依赖？

编辑：我目前通过解压缩每个属性然后在反序列化时重新整​​理消息来实现此目的。在我看来，这种方法仍然不是最优的 - 有一些字段是不可序列化的，我还必须单独处理Message的各种不同的子类，例如TextMessage，ByteMessage等。

private void writeObject(java.io.ObjectOutputStream out)
            throws IOException{
        HashMap<String, Object> properties = new HashMap <String, Object> ();
        HashMap<Integer, Object> metaData = new HashMap<Integer, Object>();
        try {
            Enumeration srcProperties = message.getPropertyNames();
            while (srcProperties.hasMoreElements()) {
                String propertyName = (String) srcProperties.nextElement ();
                properties.put(propertyName, message.getObjectProperty (propertyName));
            }
            //FIXME text/other body not preserved yet, have to preserve the message type eg Text/Byte etc continue after confirming with aditya
            metaData.put(KEY_JMS_CORRELATION_ID, message.getJMSCorrelationID());
            metaData.put(KEY_JMS_DELIVERY_MODE, message.getJMSDeliveryMode());
            metaData.put(KEY_JMS_EXPIRATION, message.getJMSExpiration());
            metaData.put(KEY_JMS_TIMESTAMP, message.getJMSTimestamp());
            metaData.put(KEY_JMS_MESSAGE_ID, message.getJMSMessageID());
            metaData.put(KEY_JMS_PRIORITY, message.getJMSPriority());
            metaData.put(KEY_JMS_REPLY_TO, message.getJMSReplyTo());
            metaData.put(KEY_JMS_TYPE, message.getJMSType());
        } catch (JMSException e) {
            e.printStackTrace();
        }
        out.writeObject(properties);
        out.writeObject(metaData);
    }

    private void readObject(java.io.ObjectInputStream in)
            throws IOException, ClassNotFoundException {
        HashMap<String, Object> properties = (HashMap<String, Object>) in.readObject();
        HashMap<Integer, Object> metaData= (HashMap<Integer, Object>) in.readObject();
        System.out.println("JMSMessageUtility - Retrieving Properties: "+properties);
        System.out.println("JMSMessageUtility - Retrieving Metadata: "+metaData);

        Message message = null;
        try {
            ConnectionFactory connectionFactory = new AMQConnectionFactory(CONNECTION_BROKER);
            Destination destination = new AMQAnyDestination(QUEUE_ADDRESS);
            Connection connection = connectionFactory.createConnection();
            Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
            message = session.createMessage();
            for(Map.Entry<String, Object> property: properties.entrySet()){
                message.setObjectProperty(property.getKey(), property.getValue());
            }
            message.setJMSCorrelationID(metaData.get(KEY_JMS_CORRELATION_ID) == null? null:(String) metaData.get(KEY_JMS_CORRELATION_ID));
            message.setJMSDeliveryMode((Integer) metaData.get(KEY_JMS_DELIVERY_MODE));
            message.setJMSDestination(destination);
            message.setJMSExpiration((Long) metaData.get(KEY_JMS_EXPIRATION));
            message.setJMSTimestamp((Long) metaData.get(KEY_JMS_TIMESTAMP));
            message.setJMSMessageID((String) metaData.get(KEY_JMS_MESSAGE_ID));
            message.setJMSPriority((Integer) metaData.get(KEY_JMS_PRIORITY));
            message.setJMSReplyTo(null); // no idea what to do with this
            message.setJMSType(metaData.get(KEY_JMS_TYPE) == null? null:(String) metaData.get(KEY_JMS_TYPE));
        } catch (URLSyntaxException e) {
            e.printStackTrace();
        } catch (JMSException e) {
            e.printStackTrace();
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
        setMessage(message);
    }
