jboss.naming.context.java.jboss.exported.jboss WildFly 18 NameNotFoundException: jboss -服务NameNotFoundException

Question

我跟随Helloworld JMS示例从WildFly快速开始编写我自己的Java。当我运行Java程序时，我得到了下面的异常。有人能指导我如何访问将消息发送到JMS队列吗？我对JMS和WildFly还不熟悉。

默认情况下，在WildFly中创建的JNDI绑定对远程客户端不可用。为了将JNDI绑定公开给远程客户端，它们需要在一个特殊的名称空间- java:jboss/exported/中。但是，从远程客户端的角度来看，java:jboss/exported/并不存在，因此它只是在查找时使用了java:jboss/exported/之后的内容。

例如，connection-factory "RemoteConnectionFactory“被配置为绑定到java:jboss/exported/jms/RemoteConnectionFactory

<connection-factory name="RemoteConnectionFactory" entries="java:jboss/exported/jms/RemoteConnectionFactory" connectors="http-connector"/>

但是，远程客户端会查找jms/RemoteConnectionFactory，例如：

ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup("jms/RemoteConnectionFactory");            

在您的代码和配置中会出现这种情况。您正在使用java:jboss/exported/查找连接工厂，这是不正确的，而且您的队列配置没有使用java:jboss/exported/。应该是这样的：

<jms-queue name="Test" entries="java:jboss/exported/jms/queue/test"/>

那么您的代码实际上将如下所示：

Destination destination = (Destination) namingContext.lookup("jms/queue/test");

顺便说一句，如果您只是简单地将代码和配置留在最初的快速启动程序中，那么一切都会正常工作。
