Question

我在队列中发布消息（一次发送50条消息）时遇到两个异常。我在我的项目中使用ThreadLocal（也包括JMS发布类）。我真的不知道为什么会这样。任何进一步行动的帮助表示赞赏。提前谢谢。

要发布的代码::

try {
        QueueConnectionFactory queueFactory = null;
        queueFactory = getQueueConnectionFactory(ConnectionFactoryJNDIName);
        // Create a QueueConnection
        queueConnection = queueFactory.createQueueConnection();
        try {
                // Create a QueueSession
                queueSession = queueConnection.createQueueSession(true,   Session.AUTO_ACKNOWLEDGE);
                Queue queue = getQueue(queueJNDIName);                  
                // Create the Publisher
                queueSender = queueSession.createSender(queue);
                // Create a message
                ObjectMessage objMsg = queueSession.createObjectMessage(object);
                // Publish the message
                queueSender.send(object);
                // Commit the session
                queueSession.commit();

            } catch (JMSException e) {
                throw e;
        } finally {
                try {
                    // Close the QueueSender
                    if (null != queueSender) {
                        queueSender.close();
                    }
                } catch (JMSException e) {
                        throw e;
                }
                try {
                    // Close the Queue Session
                    if (null != queueSession) {
                        queueSession.close();
                    }
                } catch (JMSException e) {
                    throw e;
                }
                try {
                    // Close the QueueConnection
                    if (null != queueConnection) {
                        queueConnection.close();
                    }
                } catch (JMSException e) {
                    throw e;
                }
    }  catch (Exception e) {
        throw e;
    }

导致问题的原因是ThreadLocal。在开始时设置ThreadLocal没有解决它。删除ThreadLocal后，问题已解决。
