Wildfly 10和RabbitMQ JDNI配置的主机名问题

如何解决Wildfly 10和RabbitMQ JDNI配置的主机名问题

我正在关注本文档，以使用RabbitMQ为Wildfly 10配置JNDI

https://www.rabbitmq.com/jms-client.html

我使用JNDI的原因是我的应用程序与任何JMS Provider的库都没有依赖关系。这意味着，在我的应用程序中，我以后仅将javax.jms-api-2.0.jar与RabbitMQ或ActiveMQ集成。

这是我在Wildfly standalone.xml文件中的配置。

                <object-factory name="java:global/jms/ConnectionFactory1" module="com.rabbitmq.jms" 
                    class="com.rabbitmq.jms.admin.RMQObjectFactory">
                    <environment>
                        <property name="className" value="javax.jms.ConnectionFactory"/>
                        <property name="virtualHost" value="/"/>
                        <property name="host" value="rabbitmq_server"/>
                        <property name="port" value="5672"/>
                    </environment>
                </object-factory>

这是集成的源代码。

            Context context = new InitialContext();
            ConnectionFactory connectionFactory
                    = (ConnectionFactory) context.lookup("java:global/jms/ConnectionFactory1");
            if (connectionFactory == null) {
                System.out.println("Cannot initiallize connection factory.");
                return;
            }
            Connection connection = connectionFactory.createConnection(
                    "guest","guest");
            
            if (connection == null) {
                System.out.println("Initiallize connection Failed.");
                return;
            }
            Session session = connection.createSession(false,QueueSession.AUTO_ACKNowLEDGE);
            if (session == null) {
                System.out.println("Initiallize session Failed.");
                return;
            }

我的问题是：在这种配置下，

如果我将值设置为IP地址=>就可以了
如果我将值设置为主机名（已经在我的主机文件中映射了IP地址）=>它将始终创建与本地主机的连接。

以前有人遇到过这个问题吗？

解决方法

是的，我刚刚发现主机名不能包含某些特殊字符，例如_。然后我将其从rabbitmq_server删除到rabbitmqserver，然后一切都很好。

希望有人得到像我这样的问题，可以按照以下步骤解决。
