jboss eap 7 - 使用資源適配器將消息發布到 IBM MQ

Question

我已將 WMQ JMS 資源適配器 (9.0.4) 安裝到我的 JBOSS EAP 7 Standalone-full.xml 並創建了連接工廠和管理員 object。

/subsystem=resource-adapters/resource-adapter=ibm-mq-resource-adapter:add(archive=wmq.jmsra-9.0.4.0.rar, transaction-support=NoTransaction)

/subsystem=resource-adapters/resource-adapter=ibm-mq-resource-adapter/admin-objects=queue-ao1:add(class-name=com.ibm.mq.connector.outbound.MQQueueProxy, jndi-name=java:jboss/outbound)

/subsystem=resource-adapters/resource-adapter=ibm-mq-resource-adapter/admin-objects=queue-ao1/config-properties=baseQueueName:add(value=TEST1)
/subsystem=resource-adapters/resource-adapter=ibm-mq-resource-adapter/admin-objects=queue-ao1/config-properties=baseQueueManagerName:add(value=TESTMANAGER)

連接定義：

<connection-definition class-name="com.ibm.mq.connector.outbound.ManagedConnectionFactoryImpl" jndi-name="java:jboss/mqSeriesJMSFactoryoutbound" tracking="false" pool-name="mq-cd">
 <config-property name="channel">
                 SYSTEM.DEF.XXX
</config-property>
                            <config-property name="hostName">
                                XX-XXX
                            </config-property>
                            <config-property name="transportType">
                                CLIENT
                            </config-property>
                            <config-property name="queueManager">
                                TESTMANAGER
                            </config-property>
                            <config-property name="port">
                                1414
                            </config-property>
                        </connection-definition>

據我了解，如果我從連接工廠 mqSeriesJMSFactoryoutbound 向出站隊列發布消息，我應該能夠到達 IBM MQ。 我嘗試使用下面的代碼來查找連接工廠，但我得到了命名 notfound 異常。 請幫忙

public class TestQueueConnection {

    // Set up all the default values
    private static final String DEFAULT_MESSAGE = "Hello, World! successfull";
    private static final String DEFAULT_CONNECTION_FACTORY = "java:jboss/mqSeriesJMSFactoryoutbound";
    private static final String DEFAULT_DESTINATION = "java:jboss/outbound";
    private static final String DEFAULT_MESSAGE_COUNT = "1";
    private static final String DEFAULT_USERNAME = "jmsuser";
    private static final String DEFAULT_PASSWORD = "jmsuser123";
    private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";
    private static final String PROVIDER_URL = "http-remoting://127.0.0.1:8070";

    public static void main(String[] args) throws JMSException {

        Context namingContext = null;

        try {
             String userName = System.getProperty("username", DEFAULT_USERNAME);
             String password = System.getProperty("password", DEFAULT_PASSWORD);

            // Set up the namingContext for the JNDI lookup
            final Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
            env.put(Context.PROVIDER_URL, System.getProperty(Context.PROVIDER_URL, PROVIDER_URL));
            namingContext = new InitialContext(env);

            // Perform the JNDI lookups
            String connectionFactoryString = System.getProperty("connection.factory", DEFAULT_CONNECTION_FACTORY);
             namingContext.lookup(connectionFactoryString);
            QueueConnectionFactory connectionFactory = (QueueConnectionFactory) 
            JMSContext jmsContext = connectionFactory.createContext(DEFAULT_USERNAME, DEFAULT_PASSWORD);
    

            Queue destination = (Queue) namingContext.lookup(DEFAULT_DESTINATION);
            
            jmsContext.createProducer().send(destination, DEFAULT_MESSAGE);
            System.out.println("><><><><><><>< MESSAGE POSTED <><><><><><><>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>" );
            
        } catch (NamingException e) {
            e.printStackTrace();
        } finally {
            if (namingContext != null) {
                try {
                    namingContext.close();
                } catch (NamingException e) {
                }
            }
        }
    }

對上述內容進行了一些更改。

1. 在連接定義中，使用托管隊列ConnectionFactoryImpl 代替 com.ibm.mq.connector.outbound.ManagedConnectionFactoryImpl 以避免運行時 class 轉換異常。

2. RA 創建的連接工廠在其 JVM 之外無法訪問。 編寫了一個 servlet 來訪問這些連接工廠。 我能夠連接下面的代碼。

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        response.getWriter().append("Served at: ").append(request.getContextPath());
        
        Context namingContext = null;
        String connectionFactoryString = "mqSeriesJMSFactoryoutbound";
        String queueName = "outbound";
        
        MessageProducer producer = null;
        Session session = null;
        Connection conn =null;
        try {
            namingContext = new InitialContext();
            
            QueueConnectionFactory connectionFactory = (QueueConnectionFactory) namingContext.lookup(connectionFactoryString);
            Queue destination = (Queue) namingContext.lookup(queueName);
            
            conn = connectionFactory.createConnection();
            session = conn.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);
            producer = session.createProducer(destination);
            TextMessage message = session.createTextMessage();
            message.setText(msg);
            
            producer.send(message,
                    Message.DEFAULT_DELIVERY_MODE,
                    Message.DEFAULT_PRIORITY,
                    Message.DEFAULT_TIME_TO_LIVE);
            
                      
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
        finally {
            
            // Close the message producer
            try {
              if (producer != null) producer.close();
            }
            catch (JMSException e) {
              System.err.println("Failed to close message producer: " + e);
            }
            
            // Close the session
            try {
              if (session != null) session.close();
            }
            catch (JMSException e) {
              System.err.println("Failed to close session: " + e);
            }
            
            // Close the connection
            try {
                if(conn != null)
              conn.close();
            }
            catch (JMSException e) {
              System.err.println("Failed to close connection: " + e);
            }
            
          }
        
        
        
        
    }
