我想在核心HornetQ的客户端持久化队列。问题是,当我停止服务器队列和数据将被销毁。如何使队列持久? 我的代码是:如何使HornetQ在队列中坚持2.2.5核心客户?

// Step 1. Create the Configuration, and set the properties accordingly
Configuration configuration = new ConfigurationImpl();
configuration.setPersistenceEnabled(false);
configuration.setSecurityEnabled(false);
configuration.getAcceptorConfigurations().add(new TransportConfiguration(InVMAcceptorFactory.class.getName()));
// Step 2. Create and start the server
HornetQServer server = HornetQServers.newHornetQServer(configuration);
server.start();
// Step 3. As we are not using a JNDI environment we instantiate the objects directly
ServerLocator serverLocator = HornetQClient.createServerLocatorWithoutHA(new TransportConfiguration(InVMConnectorFactory.class.getName()));
ClientSessionFactory sf = serverLocator.createSessionFactory();
// Step 4. Create a core queue
ClientSession coreSession = sf.createSession(false, false, false);
final String queueName = "queue.exampleQueue";
coreSession.createQueue(queueName, queueName, true);
coreSession.close();
ClientSession session = null;
try

session = sf.createSession();

// Step 6. Create and send a message

// Step 8. Receive the message.

为什么不在这里粘贴代码? - 并执行configuration.setPersistenceEnabled(假)有事情做与队列不坚持? (只是在黑暗中猜测) – stakx
我试图与configuration.setPersistenceEnabled(真);但它给了我“java.lang.UnsatisfiedLinkError”异常。 –
你能添加到此处的代码编辑您原来的问题?这对未来的参考文献来说会好得多..因为没有什么能保证你制作的paste.bin会永远活着。 –
