我正在尝试在我的应用程序中运行HornetQ。以编程方式配置会导致this错误。
所以我一直在尝试通过xml文件设置配置。服务器启动成功，但尝试创建客户端会话时出错。
这是我的代码
ClientSession session = null;
try {
EmbeddedHornetQ embedded = new EmbeddedHornetQ();
try {
embedded.start();
} catch (Exception ex) {
log.error("Error starting MQServer", ex);
throw new RuntimeException(ex);
}
ClientSessionFactory sessionFactory = HornetQClient.createServerLocatorWithoutHA(
new TransportConfiguration(
InVMConnectorFactory.class.getName())).createSessionFactory();
session = sessionFactory.createSession();
final String queueName = "queue.exampleQueue";
session.createQueue(queueName, queueName, true);
}catch(Exception ex) {
log.error("error", ex);
}
return session;
当它尝试连接时，我收到此错误：

在为代码配置AIO之前，您必须先测试AIO的可用性。
我们的服务器在检查后执行此操作，现在您必须对嵌入式代码执行相同操作。 （我们基本上决定尊重您的选择，如果不可用则发出错误。）
boolean supportsAIO = AIOSequentialFileFactory.isSupported();
if (supportsAIO)
{
config.setJournalType(JournalType.ASYNCIO);
}
else
{
config.setJournalType(JournalType.NIO);
}
HornetQ有一个JIRA开放来改进这个并自动进行切换，但我们遇到的用户实际上想要嵌入式错误。很难取悦所有人！
