Question

我为WildFly10编写基于Java的JMS客户端，我遇到了问题

   Properties props = new Properties();
   props.put(Context.INITIAL_CONTEXT_FACTORY,        "org.jboss.naming.remote.client.InitialContextFactory");
   props.put(Context.PROVIDER_URL, WILDFLY_REMOTING_URL);   // NOTICE: "http-     remoting" and port "8080"
   props.put(Context.SECURITY_PRINCIPAL, JMS_USERNAME);
   props.put(Context.SECURITY_CREDENTIALS, JMS_PASSWORD);
   //props.put("jboss.naming.client.ejb.context", true);
   context = new InitialContext(props);

我运行你的客户端代码，我收到了这个错误：

我改变了这样的代码并在我的项目中添加了activemq lib：

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.apache.activemq.jndi.ActiveMQInitialContextFactory");
props.put(Context.PROVIDER_URL, WILDFLY_REMOTING_URL);   // NOTICE: "http-remoting" and port "8080"
props.put(Context.SECURITY_PRINCIPAL, JMS_USERNAME);
props.put(Context.SECURITY_CREDENTIALS, JMS_PASSWORD);

我收到了这个错误：

你可以帮我解决一下错误吗??? 感谢。

工作示例：

public class JMSClient {
   private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
   private static final String PROVIDER_URL = "http-remoting://127.0.0.1:8080";
   private static final String CONNECTION_FACTORY = "jms/RemoteConnectionFactory";
   private static final String DESTINATION = "topic/irisWebBroadcaster";
   private static final String USERNAME = "jmsuser";
   private static final String PASSWORD = "qqq";

   public static void main(String[] args) {

      Context namingContext = null;
      JMSContext context = null;

      try {
         final Properties env = new Properties();
         env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
         env.put(Context.PROVIDER_URL, PROVIDER_URL);
         env.put(Context.SECURITY_PRINCIPAL, USERNAME);
         env.put(Context.SECURITY_CREDENTIALS, PASSWORD);

         namingContext = new InitialContext(env);

         ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup(CONNECTION_FACTORY);

         Destination destination = (Destination) namingContext.lookup(DESTINATION);

         context = connectionFactory.createContext(USERNAME, PASSWORD);

         JMSProducer producer = context.createProducer();
         producer.send(destination, "TEST");
      } catch (Exception e) {
          // print error messge
      } finally {
          if (namingContext != null) {
             try {
                namingContext.close();
             } catch (NamingException e) {
                // print error messge
             }
          }

          if (context != null) {
             context.close();
          }
      }
 }

}

如果您遇到日志记录问题，可以添加类似的内容：

  InternalLoggerFactory.setDefaultFactory(new Log4JLoggerFactory());
  PropertyConfigurator.configure("conf/log4j.properties");

我看到Rudik给出的答案尚未被接受，因此发表了对此问题的看法。

测试用例

 @Test
    public void sendMessagesToWildfly10() throws IOException, NamingException {
        String Message = "Hello, World!";
        String connectionFactoryJNDIName = "jms/RemoteConnectionFactory";
        String queueName = "jms/queue/TestQueue";
        Context namingContext = null;
        JMSContext context = null;
        try {
            Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.remote.client.InitialContextFactory");
            env.put(Context.PROVIDER_URL, "http-remoting://localhost:8470");
            // Below May Not be needed if you have turned off the security for Messaging
            env.put(Context.SECURITY_PRINCIPAL, "guest");
            env.put(Context.SECURITY_CREDENTIALS, "guest");
            namingContext = new InitialContext(env);
            ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup(connectionFactoryJNDIName);
            Destination destination = (Destination) namingContext.lookup(queueName);
            context = connectionFactory.createContext("userName", "password");
            JMSProducer producer = context.createProducer();
            for (int i = 0; i < 10; i++) {
                producer.send(destination, Message+" - "+i);
              }

            JMSConsumer consumer = context.createConsumer(destination);

           for (int i = 0; i < 10; i++) {
                String text = consumer.receiveBody(String.class, 5000);
            }

        } catch (Exception e) {
            e.printStackTrace();

        } finally {
            if (namingContext != null) {
                namingContext.close();
            }
            if (context != null) {
                context.close();
            }
        }

    }

您需要在类路径中添加下面提到的Jars / dependencies。你可以在Wildfly / modules中找到大多数

Answer 3

如果JMS客户端在WildFly应用程序中运行，则必须添加org.apache.activemq.artemis模块作为对部署的依赖，以避免 java.lang.ClassNotFoundException：org.apache.activemq.artemis。 jms.client.ActiveMQJMSConnectionFactory ，例如为answered here。

否则（独立的java应用程序） - 需要将jboss-client.jar包含在class-path中。注意：根据您的目标WildFly版本获取jboss-client.jar，因为它在WildFLy 8和10之间有所不同。
