ejb jms hornetq jboss7.1.1

1.首先是要add-user.bat,添加用户,在jboss的bin目录下运行add-user.bat

角色是guest不是gutst。照样添加就可以了.之后就是一路yes敲下去.

2.替换XML文件,CMD命令我用的不熟,折腾半天也没运行起JBOSS,伤心之余就跑去更换JBOSS的启动使用的XML文件了.D:\software\jboss-as-7.1.3.Final\standalone\configuration文件夹下,默认使用standalone.xml,你把他备份好,然后把standalone-full.xml的名字改为standalone.xml.因为那个啥,JBOSS7默认是没带JMS的.

3.修改Jboss配置文件standalone-full.xml(也就是现在的standalone.xml)，找到hornetq-server节点，在该节点下的jms-destinations确定含有以下配置.

<jms-destinations>

                    <jms-queue name="testQueue">

                        <entry name="queue/test"/>

                        <entry name="java:jboss/exported/jms/queue/test"/>

                    </jms-queue>

                    <jms-topic name="ServerNotificationTopic">

                        <entry name="topic/ServerNotification"/>

                        <entry name="java:jboss/exported/jms/topic/ServerNotification"/>

                    </jms-topic>

                </jms-destinations>

没就加上.

4.进入JBOSS控制台,看到JMS就是正确的了.擦,我的standalone.bat无法运行..才发现.不过Eclipse运行貌似一点问题没,JBOSS TOLL插件我全装了,汗.如图:

5.开始写代码,我都是写的main方法.注意把D:\software\jboss-as-7.1.3.Final\bin\client下的jar包弄上.

第一个是客户端的消息生产者:

package org.credo.jms;
 
import java.util.concurrent.CountDownLatch;

import java.util.concurrent.TimeUnit;

import java.util.logging.Logger;

import java.util.Properties;
 
import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.Destination;

import javax.jms.MessageProducer;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.naming.Context;

import javax.naming.InitialContext;
 
/**

 * <p>Description:JMS客户端消息生产者 </p>

 */

public class JMSProducer {

    private static final Logger log = Logger.getLogger(JMSProducer.class.getName());
 
    private static final String DEFAULT_MESSAGE = "the 4 message!";

    // xml文件272行

    private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";

    // xml文件293行,初次找JBOSS的JNDI太不容易了

    private static final String DEFAULT_DESTINATION = "jms/queue/test";

    private static final String DEFAULT_MESSAGE_COUNT = "1";
 
    private static final String DEFAULT_USERNAME = "lion";

    private static final String DEFAULT_PASSWORD = "123456";

    private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";

    private static final String PROVIDER_URL = "remote://localhost:4447";
 
    public static void main(String[] args) throws Exception {

        Context context=null;

        Connection connection=null;

        try {

            // 设置上下文的JNDI查找

            log.info("设置JNDI访问环境信息也就是设置应用服务器的上下文信息!");

            final Properties env = new Properties();

            env.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);// 该KEY的值为初始化Context的工厂类,JNDI驱动的类名

            env.put(Context.PROVIDER_URL,  PROVIDER_URL);// 该KEY的值为Context服务提供者的URL.命名服务提供者的URL

            env.put(Context.SECURITY_PRINCIPAL, DEFAULT_USERNAME);

            env.put(Context.SECURITY_CREDENTIALS, DEFAULT_PASSWORD);//应用用户的登录名,密码.

            // 获取到InitialContext对象.

            context = new InitialContext(env);

            log.info("初始化上下文,'JNDI驱动类名','服务提供者URL','应用用户的账户','密码'完毕.");
 
            log.info("获取连接工厂!");

            ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup(DEFAULT_CONNECTION_FACTORY);

            log.info("获取目的地!");

            Destination destination = (Destination) context.lookup(DEFAULT_DESTINATION);
 
            // 创建JMS连接、会话、生产者和消费者

            connection = connectionFactory.createConnection(DEFAULT_USERNAME, DEFAULT_PASSWORD);

            Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

            MessageProducer producer = session.createProducer(destination);

            connection.start();
 
            int count = Integer.parseInt(DEFAULT_MESSAGE_COUNT);

            // 发送特定数目的消息

            TextMessage message = null;

            for (int i = 0; i < count; i++) {

                message = session.createTextMessage(DEFAULT_MESSAGE);

                producer.send(message);

                log.info("message:"+message);

                log.info("message:"+DEFAULT_MESSAGE);

            }

            // 等待30秒退出

            CountDownLatch latch = new CountDownLatch(1);

            latch.await(30, TimeUnit.SECONDS);

        } catch (Exception e) {

            log.severe(e.getMessage());

            throw e;

        } finally {

            if (context != null) {

                context.close();

            }

            // 关闭连接负责会话,生产商和消费者

            if (connection != null) {

                connection.close();

            }

        }

    }
}

每次运行后如图:

JBOSS端如图所示:

每次向JBOSS的Queue发送消息成功的话,上面红圈的数字都会+1.

如果电脑重启,JBOSS重启,消息仍然是存在的.如果被接收了的话,消息就是消失.

2.客户端消费者代码:

package org.credo.jms;
 
import java.util.Properties;

import java.util.concurrent.CountDownLatch;

import java.util.concurrent.TimeUnit;

import java.util.logging.Logger;
 
import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.Destination;

import javax.jms.MessageConsumer;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.naming.Context;

import javax.naming.InitialContext;
 
public class JMSConsumer {

    private static final Logger log = Logger.getLogger(JMSConsumer.class.getName());
 
    private static final String DEFAULT_CONNECTION_FACTORY = "jms/RemoteConnectionFactory";

    private static final String DEFAULT_DESTINATION = "jms/queue/test";

    private static final String DEFAULT_USERNAME = "lion";

    private static final String DEFAULT_PASSWORD = "123456";

    private static final String INITIAL_CONTEXT_FACTORY = "org.jboss.naming.remote.client.InitialContextFactory";

    private static final String PROVIDER_URL = "remote://localhost:4447";
 
    public static void main(String[] args) throws Exception {
 
        ConnectionFactory connectionFactory = null;

        Connection connection = null;

        Session session = null;

        MessageConsumer consumer = null;

        Destination destination = null;

        TextMessage message = null;

        Context 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, DEFAULT_USERNAME);

            env.put(Context.SECURITY_CREDENTIALS, DEFAULT_PASSWORD);

            context = new InitialContext(env);
 
            connectionFactory = (ConnectionFactory) context.lookup(DEFAULT_CONNECTION_FACTORY);

            destination = (Destination) context.lookup(DEFAULT_DESTINATION);
 
            connection = connectionFactory.createConnection(DEFAULT_USERNAME, DEFAULT_PASSWORD);

            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

            consumer = session.createConsumer(destination);

            connection.start();
 
            // 等待30秒退出

            CountDownLatch latch = new CountDownLatch(1);

            while (message == null) {

                log.info("开始从JBOSS端接收信息-----");

                message = (TextMessage) consumer.receive(5000);

                latch.await(1, TimeUnit.SECONDS);

            }

            log.info("接收到的消息的内容:" + message.getText());

        } catch (Exception e) {

            log.severe(e.getMessage());

            throw e;

        } finally {

            if (context != null) {

                context.close();

            }

            if (connection != null) {

                connection.close();

            }

        }

    }
