我有一个变量 - “protected static Context jndi;”在我的班级中,“Context”是一个界面。当我尝试在下面提到的方法中访问它时,它会生成标题中提到的声纳违规
public JMSQueueResource createQueueResource(String queueBindingName, String qcfBindingName, boolean messagePersisted, boolean autoAcknowledge, boolean nonJMS) throws JMSException, NamingException {
JMSQueueResource qResource = new JMSQueueResource();
try {
jndi = createInitialContext();
if (queueConnectionFactory == null) {
queueConnectionFactory = (QueueConnectionFactory) lookup(jndi, qcfBindingName);
}
qResource.theQueueConnection = queueConnectionFactory.createQueueConnection();
if (autoAcknowledge) {
qResource.theQueueSession = qResource.theQueueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
}
else {
qResource.theQueueSession = qResource.theQueueConnection.createQueueSession(false, Session.CLIENT_ACKNOWLEDGE);
}
Queue queue = (Queue) lookup(jndi, queueBindingName);
//if (nonJMS && queue instanceof com.ibm.mq.jms.MQQueue) {
// com.ibm.mq.jms.MQQueue q = (com.ibm.mq.jms.MQQueue) queue;
// q.setTargetClient(JMSC.MQJMS_CLIENT_NONJMS_MQ);
//}
qResource.theQueueSender = qResource.theQueueSession.createSender(queue);
if (messagePersisted) {
qResource.theQueueSender.setDeliveryMode(DeliveryMode.PERSISTENT);
}
else {
qResource.theQueueSender.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
}
qResource.theQueueConnection.start();
}
catch (JMSException jmse) {
throw jmse;
}
catch (NamingException ne) {
throw ne;
}
finally {
if(jndi != null){
jndi.close();
}
}
return qResource;
}
我可以看到有人建议使用Atomic Integer包装器。解决这个问题的最佳方法是什么?
