廉頗老矣，尚能飯否

Apache ActiveMQ學(xué)習(xí)筆記【mq的方式有兩種：點(diǎn)到點(diǎn)和發(fā)布/訂閱】

一.簡(jiǎn)介ActiveMQ

ActiveMQ 是最流行的，能力強(qiáng)勁的開源消息總線。ActiveMQ 是一個(gè)完全支持JMS1.1和J2EE 1.4規(guī)范的 JMS Provider實(shí)現(xiàn)

二.下載ActiveMQ

首先去http://activemq.apache.org/download.html 下載穩(wěn)定版本4.1.0release

Download Here

Description ==Download Link ==PGP Signature file of download

Binary for Windows== apache-activemq-4.1.0-incubator.zip== incubator-activemq-4.1.0.zip.asc

Binary-for-Unix/Linux/Cygwin==apache-activemq-4.1.0-incubator.tar.gz==incubator-activemq-4.1.0.tar.gz.as 

解壓后目錄如下:

+bin (windows下面的bat和unix/linux下面的sh)

+conf (activeMQ配置目錄,包含最基本的activeMQ配置文件)

+data (默認(rèn)是空的)

+docs (index,replease版本里面沒(méi)有文檔,-.-b不知道為啥不帶)

+example (幾個(gè)例子

+lib (activemMQ使用到的lib)

-apache-activemq-4.1-incubator.jar (ActiveMQ的binary)

-LICENSE.txt

-NOTICE.txt

-README.txt

-user-guide.html

三.啟動(dòng)ActiveMQ

可以使用bin\activemq.bat(activemq) 啟動(dòng),如果一切順利,你就會(huì)看見類似下面的信息(此處解壓到D盤根目錄下).幾個(gè)小提示

1. 這個(gè)僅僅是最基礎(chǔ)的ActiveMQ的配置,很多地方都沒(méi)有配置因此不要直接使用這個(gè)配置用于生產(chǎn)系統(tǒng)

2. 有的時(shí)候由于端口被占用,導(dǎo)致ActiveMQ錯(cuò)誤,ActiveMQ可能需要以下端口1099(JMX),61616(默認(rèn)的TransportConnector)

3. 如果沒(méi)有物理網(wǎng)卡,或者M(jìn)S的LoopBackAdpater Multicast會(huì)報(bào)一個(gè)錯(cuò)誤

四.監(jiān)控ActiveMQ

啟動(dòng)JDK自帶的java控制臺(tái)查看程序查看客戶端(如C:\jdk1.6.0_07\bin\jconsole.exe)

遠(yuǎn)程進(jìn)程:127.0.0.1:1099

五. 測(cè)試ActiveMQ

由于ActiveMQ是一個(gè)獨(dú)立的jms provider,所以我們不需要其他任何第三方服務(wù)器就可以馬上做我們的測(cè)試了.編譯example目錄下面的程序ProducerTool/ConsumerTool 是JMS參考里面提到的典型應(yīng)用,Producer產(chǎn)生消息,Consumer消費(fèi)消息，而且這個(gè)例子還可以加入?yún)?shù)幫助你測(cè)試剛才啟動(dòng)的本地ActiveMQ或者是遠(yuǎn)程的ActiveMQ

ProducerTool [url] broker的地址,默認(rèn)的是tcp://localhost:61616

[true|flase] 是否使用topic,默認(rèn)是false

[subject] subject的名字,默認(rèn)是TOOL.DEFAULT

[durabl] 是否持久化消息,默認(rèn)是false

[messagecount] 發(fā)送消息數(shù)量,默認(rèn)是10

[messagesize] 消息長(zhǎng)度,默認(rèn)是255

[clientID] durable為true的時(shí)候,需要配置clientID

[timeToLive] 消息存活時(shí)間

[sleepTime] 發(fā)送消息中間的休眠時(shí)間

[transacte] 是否采用事務(wù)

ConsumerTool [url] broker的地址,默認(rèn)的是tcp://localhost:61616

[true|flase] 是否使用topic,默認(rèn)是false

[subject] subject的名字,默認(rèn)是TOOL.DEFAULT

[durabl] 是否持久化消息,默認(rèn)是false

[maxiumMessages] 接受最大消息數(shù)量,0表示不限制

[clientID] durable為true的時(shí)候,需要配置clientID

[transacte] 是否采用事務(wù)

[sleepTime] 接受消息中間的休眠時(shí)間,默認(rèn)是0,onMeesage方法不休眠

[receiveTimeOut] 接受超時(shí)

六.使用應(yīng)用程序發(fā)送點(diǎn)到點(diǎn)消息隊(duì)列

TestSender類

package test;

import javax.jms.DeliveryMode;

import javax.jms.JMSException;

import javax.jms.Message;

import javax.jms.Session;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.FileSystemXmlApplicationContext;

import org.springframework.jms.core.JmsTemplate;

import org.springframework.jms.core.MessageCreator;

public class TestSender {

    public static void main(String[] args) {

        ApplicationContext ctx = new FileSystemXmlApplicationContext("conf/applicationContext.xml");

        JmsTemplate template = (JmsTemplate) ctx.getBean("myJmsTemplate");

        template.setDeliveryMode(DeliveryMode.PERSISTENT);

        template.send(new MessageCreator() {

            public Message createMessage(Session session) throws JMSException {

                Message message = session.createTextMessage();

                message.setStringProperty("name", "wangwu");

                message.setStringProperty("password", "ww");

                System.out.println("send success");

                return message;

            }

        });

    }

}

applicationContext.xml配置文件

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:amq="http://activemq.org/config/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

import javax.jms.Message;

import javax.jms.ObjectMessage;

import javax.jms.Session;

import javax.jms.StreamMessage;

import javax.jms.TextMessage;

 

import org.springframework.jms.listener.SessionAwareMessageListener;

public class ExampleListener implements SessionAwareMessageListener {

    public void onMessage(Message message, Session session) throws JMSException {

        if(message instanceof TextMessage) {

            System.out.println("TextMessage begin");

            System.out.println("name = " + message.getStringProperty("name"));

            System.out.println("password = " +message.getStringProperty("password"));

        }

        if (message instanceof ObjectMessage) {

            System.out.println("ObjectMessage");

        } else if (message instanceof TextMessage) {

            System.out.println("TextMessage");

        } else if (message instanceof StreamMessage) {

            System.out.println("StreamMessage");

        } else if (message instanceof MapMessage) {

            System.out.println("MapMessage");

        }

    }

}

TestReceiver類

package test;

import javax.jms.JMSException;

import org.springframework.context.support.FileSystemXmlApplicationContext;

public class TestReceiver {

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

        new FileSystemXmlApplicationContext("conf/context.xml");

    }

}

context.xml配置文件.

<beans xmlns="http://www.springframework.org/schema/beans"

        <property name="destination" ref="destinationa" />

        <property name="messageListener" ref="ExampleListener" />

    </bean>

</beans>

八. 使用WEB程序發(fā)送點(diǎn)到點(diǎn)消息隊(duì)列

TestWebSender類

package com.jl.material.adapter.impl;

import javax.jms.JMSException;

import com.jl.framework.jms.JmsManager;

import com.jl.framework.jms.JmsManagerFactory;

import com.jl.framework.jms.MessageCreateable;

import com.jl.framework.jms.MessageCreatorDefault;

import com.jl.framework.jms.util.JmsUtil;

import com.jl.material.util.MaterialConstants;

public class TestWebSender{

    public void sender(String name, String password) {

        MessageCreateable mc = new MessageCreatorDefault();       

        mc.setStringProperty("name", name);

        mc.setStringProperty("password", password);       

        JmsManagerFactory jmsManagerFactory = new JmsManagerFactory();

        JmsManager jmsTXManager = jmsManagerFactory.createJmsManager(MaterialConstants.MATERIAL_MODULE_NAME);

        try {

            jmsTXManager.send(JmsUtil.getDestinationFromConfig("quality_synVerifyBatch_queue_M2Q"), mc);

            jmsTXManager.commit();

        } catch (JMSException e) {

            jmsTXManager.rollback();

            throw new RuntimeException(e);

        }

    }

}

九. 使用WEB程序接受點(diǎn)到點(diǎn)消息隊(duì)列

TestWebReceiver類

    public void mdCallback(TextMessage textMessage) throws Exception {

        String name = textMessage.getStringProperty("name");

        String password = textMessage.getStringProperty("password");

        System.out.println("name = " + name);

        System.out.println("password = " + password);

    }

    public void mdCallback(StreamMessage arg0) throws Exception {}

    public void mdCallback(MapMessage arg0) throws Exception {}

}

test_JMS_Spring_Listener.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>

<beans>

    <bean id="test_testWebReceiver" class="com.jl.framework.jms.util.support.JMSRecieveBean">

十. 使用發(fā)布/訂閱方式
使用該方式的發(fā)布方基本與點(diǎn)到點(diǎn)方式一樣，區(qū)別只在隊(duì)列名的后綴從 .Queue 變成了 .Topic
區(qū)別主要在接收方配置文件
<bean id="pound_removeBindingInfoReceiver" class="com.jl.framework.jms.util.support.JMSRecieveBean">
    <property name="jmsCallbackable">
        <bean class="com.jl.pound.adapter.impl.RemoveBindingInfoReceiver">
         <property name="initialInfomationService" ref="initialInfomationService" />
         <property name="productPoundServiceFacade" ref="productPoundServiceFacade" />
        </bean>
    </property>
 </bean>

 <bean id="pound_removeBindingInfomation_topic" class="org.apache.activemq.command.ActiveMQTopic">
   <constructor-arg><value>${CraftPound_RemoveBindingInfomation}</value></constructor-arg>
 </bean>

 <bean id="pound_listenerContainerB"
     class="com.jl.framework.jms.util.listener.JLMessageListenerContainer">

      <property name="connectionFactory" ref="jmsRecieveFactory" />
      <property name="destination" ref="pound_removeBindingInfomation_topic" />
      <property name="messageListener" ref="pound_removeBindingInfoReceiver" />
      <property name="sessionAcknowledgeModeName" value="CLIENT_ACKNOWLEDGE"></property>
      <property name="subscriptionDurable" value="true"></property>
      <property name="pubSubDomain" value="true"></property>
      <!-- <property name="clientId" value="100554"></property> -->
      <property name="clientId" ref="generateClientIdentityCode1"></property>
 </bean>

 <bean id="generateClientIdentityCode1"
   class="com.jl.pound.security.GenerateClientIdentityCode">
   <property name="prefix" value="1"></property>
 </bean>

import org.apache.log4j.Logger;
import org.springframework.beans.factory.FactoryBean;

import com.**.util.NetworkUtils;

public class GenerateClientIdentityCode implements FactoryBean {

    /**
     * LOGGER for sample classify delegate
     */
    private static final Logger LOGGER = Logger.getLogger(GenerateClientIdentityCode.class);
   
    /**
     * prefix
     */
    private String prefix;

 /**
  * @return the prefix
  */
 public String getPrefix() {
  return prefix;
 }

 /**
  * @param prefix the prefix to set
  */
 public void setPrefix(String prefix) {
  this.prefix = prefix;
 }
 
    public String generateIdentityCode() {
        String mac = NetworkUtils.getMACAddress();
        mac = prefix + mac;
        LOGGER.info("this client identity code is:" + mac);
        return mac;
    }

 public Object getObject() throws Exception {
  return generateIdentityCode();
 }

 public Class getObjectType() {
  return String.class;
 }

 public boolean isSingleton() {
  return false;
 }
}

在JMS中，Topic實(shí)現(xiàn)publish和subscribe語(yǔ)義。一條消息被publish時(shí)，它將發(fā)到所有感興趣的訂閱者，所以零到多個(gè)subscriber將接收到消息的一個(gè)拷貝。但是在消息代理接收到消息時(shí)，只有激活訂閱的subscriber能夠獲得消息的一個(gè)拷貝。

JMS Queue執(zhí)行l(wèi)oad balancer語(yǔ)義。一條消息僅能被一個(gè)consumer收到。如果在message發(fā)送的時(shí)候沒(méi)有可用的consumer，那么它將被保存一直到能處理該message的consumer可用。如果一個(gè)consumer收到一條message后卻不響應(yīng)它，那么這條消息將被轉(zhuǎn)到另一個(gè)consumer那兒。一個(gè)Queue可以有很多consumer，并且在多個(gè)可用的consumer中負(fù)載均衡

可以使用queue方式發(fā)送注冊(cè)郵件 好友動(dòng)態(tài)數(shù)據(jù)等

<一>表說(shuō)明:
當(dāng)在啟動(dòng)ActiveMQ時(shí),先判斷表是否存在,如果不存在,將去創(chuàng)建表,如下:
(1)ACTIVEMQ_ACKS:持久訂閱者列表
1.CONTAINER:類型://主題
如:topic://basicInfo.topic
2.SUB_DEST:應(yīng)該是描述,與1內(nèi)容相同
3.CLIENT_ID:持久訂閱者的標(biāo)志ID,必須唯一
4.SUB_NAME:持久訂閱者的名稱.(durableSubscriptionName)
5.SELECTOR:消息選擇器,consumer可以選擇自己想要的
6.LAST_ACKED_ID:最后一次確認(rèn)ID,這個(gè)字段存的該該訂閱者最后一次收到的消息的ID

(2)ACTIVEMQ_LOCK:進(jìn)行數(shù)據(jù)訪問(wèn)的排斥鎖
1.ID:值為1
2.TIME:時(shí)間
3.BROKER_NAME:broker的名稱
   這個(gè)表似為集群使用,但現(xiàn)在ActiveMQ并不能共享數(shù)據(jù)庫(kù).

(3)ACTIVEMQ_MSGS:存儲(chǔ)Queue和Topic消息的表
1.ID:消息的ID
2.CONTAINER: 類型://主題
如:queue://my.queue
Topic://basicInfo.topic
3.MSGID_PROD:發(fā)送消息者的標(biāo)志
MSGID_PROD =ID:[computerName][…..]
注意computerName,不要使用中文,消息對(duì)象中會(huì)存儲(chǔ)這個(gè)部分,解析connectID時(shí)會(huì)出現(xiàn)Bad String錯(cuò)誤.
4.MSGID_SEQ:還不知用處
5.EXPIRATION:到期時(shí)間.
6.MSG:消息本身,Blob類型.
可以在JmsTemplate發(fā)送配置中,加上<property name=”timeToLive” value=”432000000”/>,5天的生命期,如果消息一直沒(méi)有被處理,消息會(huì)被刪除,但是表中會(huì)存在CONTAINER為queue://ActiveMQ.DLQ的記錄.也就是說(shuō),相當(dāng)于將過(guò)期的消息發(fā)給了一個(gè)ActiveMQ自定義的刪除隊(duì)列..

<二>關(guān)于ActiveMQ的持久訂閱消息刪除操作
1.主題消息只有一條,所有訂閱了這個(gè)消息的持久訂閱者都要收到消息,只有所有訂閱者收到消息并確認(rèn)(Acknowledge)之后.才會(huì)刪除.
說(shuō)明:ActiveMQ支持批量(optimizeAcknowledge為true)確認(rèn),以提高性能
2.ActiveMQ執(zhí)行刪除Topic消息的cleanup()操作的時(shí)間間隔為5 minutes..
