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

问题描述

我已经按照WildFly快速入门中的Helloworld JMS example编写了自己的Java客户端。当我运行Java程序时，出现以下异常。谁能指导我如何访问将消息发送到JMS队列？我是JMS和WildFly的新手。

            e.printStackTrace();
           // log.severe(e.getMessage());
        } finally {
            if (namingContext != null) {
                try {
                    namingContext.close();

                  //  log.severe(e.getMessage());
                }
            }
        }
    }    
}

我的standalone-full.xml如下：

解决方法

默认情况下，在WildFly中创建的

JNDI绑定不适用于远程客户端。为了向远程客户端公开JNDI绑定，它们需要位于特殊的命名空间-java:jboss/exported/中。但是，从远程客户端的角度来看，java:jboss/exported/不存在，因此它仅使用之后的 java:jboss/exported/进行查找。

例如，将connection-factory“ RemoteConnectionFactory”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，远程客户端会在jms/RemoteConnectionFactory上查找它，例如：

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

您已经在代码和配置中混淆了这一点。您正在使用java:jboss/exported/查找连接工厂，这是不正确的，并且队列配置未使用java:jboss/exported/。应该是这样的：

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

然后您的代码将有效地如下所示：

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从最初的快速入门中删除，一切都会正常工作。
