如何使用Java连接数据并将数据发送到MQ

Question

我已经在计算机（imqbrokerd.exe）中运行ActiveMQ，并获得了以下详细信息。 我已经用隐藏了机器名称

我正在使用下面的java程序来连接到此队列。

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Hashtable;
import javax.jms.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class QueueSendLinear {


    public static void main(String args[]) throws JMSException, NamingException {
         // Defines the JNDI context factory.
         final String JNDI_FACTORY="weblogic.jndi.WLInitialContextFactory";

         // Defines the JMS context factory.
         final String JMS_FACTORY="jms/TestConnectionFactory";

         // Defines the queue.
         final String QUEUE="jms/TestJMSQueue";

         QueueConnectionFactory qconFactory;
         QueueConnection qcon;
         QueueSession qsession;
         QueueSender qsender;
         Queue queue;
         TextMessage msg;
         String xml = "Sample XML comes here!! ";

         String url = "t3://<MachineName>:7676";
         Hashtable env = new Hashtable();
         env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
         env.put(Context.PROVIDER_URL, url);
         InitialContext ic =  new InitialContext(env);

         qconFactory = (QueueConnectionFactory) ic.lookup(JMS_FACTORY);
         qcon = qconFactory.createQueueConnection();
         qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
         queue = (Queue) ic.lookup(QUEUE);
         qsender = qsession.createSender(queue);
         msg = qsession.createTextMessage();
         qcon.start();
         msg.setText(xml);
         qsender.send(msg);
         qsender.close();
         qsession.close();
         qcon.close();

    }

}

在这里提问...

一种。 JNDI_FACTORY，JMS_FACTORY，QUEUE，URL中的值应该是什么？它们分别表示什么？ 湾 网址中的“ t3：//”是什么意思？ 这是协议吗？ 如果是这样，应该为活动的MQ提供什么？

仅供参考，我正在错误以下

Oct 01, 2015 7:20:58 PM com.sun.corba.se.impl.naming.namingutil.CorbalocURL badAddress

[更新＃1]：

当我使用以下代码时，出现以下错误。 我已附上我的activeMQ队列详细信息的图像。 我知道我使用的URL错误。 您能帮我选对一个吗？

Answer 1

希望对您有所帮助。我已将JMS服务器名称作为参数传递。 而且应该导入WLS库jar

private static final String CONNECTION_FACTORY_NAME ="connection factory name goes here";  

private static final String TOPIC_NAME = "Topic Name goes here";


private static final String SERVER_URL_PREFIX = "t3://";
private static final String SERVER_URL_SUFFIX = ".url.com:port";
private static final String USER = "";
private static final String PASSWORD = "";

private static final String LOCAL_DIRECTORY = "C:\\tmp\\poslog\\";


public static void main(String args[]) throws JMSException,
        NamingException, IOException, InterruptedException {

    System.out.println("start" + new Date());
    // INITIALIZE
    System.out.println("creating context for " + args[0]);
    Hashtable<String, String> properties = new Hashtable<String, String>();
    properties.put(Context.INITIAL_CONTEXT_FACTORY,
            "weblogic.jndi.WLInitialContextFactory");
    properties.put(Context.PROVIDER_URL, SERVER_URL_PREFIX + args[0] +      SERVER_URL_SUFFIX);
//properties.put(Context.SECURITY_PRINCIPAL, USER);
//properties.put(Context.SECURITY_CREDENTIALS, PASSWORD);
    InitialContext ctx = new InitialContext(properties);
    TopicConnectionFactory connectionFactory = (TopicConnectionFactory) ctx
            .lookup(CONNECTION_FACTORY_NAME);
    TopicConnection connection = connectionFactory.createTopicConnection();
    TopicSession session = connection.createTopicSession(false, 0);
    Topic topic = (Topic) ctx.lookup(TOPIC_NAME);
    TopicPublisher sender = session.createPublisher(topic);

Answer 2

JNDI_FACTORY更像是您要用来连接的驱动程序，它们通常是特定于供应商的，如果您使用的是weblogic并且是预定义的。

JMS_FACTORY是您已经在Web逻辑中为这种类型的集成预定义的连接工厂。 它负责管理与队列的连接。

您还需要在Weblogic管理控制台上预先定义/设置QUEUE。 它是对预先设置的位于weblogic上的队列的引用。

t3是您正在使用的连接类型，另一种选择可能是iiop。 t3是一种更轻量的连接类型。
