ActiveMQ5.0实战一: 安装配置ActiveMQ5.0
ActiveMQ5.0实战三:使用Spring发送,消费topic和queue消息

简介

上一篇http://www.iteye.com/topic/15317介绍了ActiveMQ5.0的安装,这一篇将介绍的配置ActiveMQ包含了很多features(详见http://activemq.apache.org/features.html ),  
不同的需求,不同的环境,需要不同的features,当然需要不同的配置。在这里我只写了最基本的配置,算是抛砖了,希望引出更多关于ActiveMQ的高级配置
假设已经正确安装ActiveMQ5.0,同时及其IP地址为192.168.1.148,具体使用时可以改为自己的IP。下面讲解的配置实现的features如下:

  1. 客户端可以通过tcp://192.168.1.148连接ActiveMQ
  2. 消息持久化保存,重启服务器不会丢失消息。
  3. 可以通过http://192.168.1.148:8161/admin监控ActiveMQ服务器

配置

ActiveMQ默认使用的是XML格式配置,从4.0版本开始用MBean的方式实现XML配置配置文件在${activemq.home}/conf目录下,文件名为activemq.xml。最新的默认配置
http://svn.apache.org/repos/asf/activemq/trunk/assembly/src/release/conf/activemq.xml 。下面为本篇文章使用的配置,及重要部分的解释。

注释

关于XML配置中元素的具体信息可以参考http://activemq.apache.org/xbean-xml-reference-50.html 下面介绍本篇配置使用的一些重要元素。

DispathPolicy

ActiveMQ支持3中不同的分发策略(避免翻译了以后误解,这里用原文):

  1. <roundRobinDispatchPolicy>:Simple dispatch policy that sends a message to every subscription that matches the message.
  2. <simpleDispatchPolicy>:Simple dispatch policy that sends a message to every subscription that matches the message.
  3. <strictOrderDispatchPolicy>:Dispatch policy that causes every subscription to see messages in the same order.

SubscriptionRecoveryPolicy

ActiveMQ支持6种恢复策略,可以自行选择使用不同的策略

  1. <fixedCountSubscriptionRecoveryPolicy>: keep a fixed count of last messages.
  2. <fixedSizedSubscriptionRecoveryPolicy>: keep a fixed amount of memory available in RAM for message history which is evicted in time order.
  3. <lastImageSubscriptionRecoveryPolicy>:only keep the last message.
  4. <noSubscriptionRecoveryPolicy>:disable recovery of messages.
  5. <queryBasedSubscriptionRecoveryPolicy>:perform a user specific query mechanism to load any messages they may have missed.
  6. <timedSubscriptionRecoveryPolicy>:keep a timed buffer of messages around in memory and use that to recover new subscriptions.

PersistenceAdapter

http://activemq.apache.org/persistence 讲解了关于persistence的信息。ActiveMQ5.0使用AMQ Message Store 持久化消息,这种方式提供了很好的性能(The AMQ Message Store is an embeddable transactional message storage solution that is extremely fast and reliable.) 默认使用该存储方式即可,如果想使用JDBC来存储,可以查找文档配置。 

Summary

本篇文章只提供了基本配置信息。如果需要更多的文章,可以查看ActiveMQ的文档。

讲了安装和简单的配置,下一篇将介绍和Sping的整合,以及多个queue,多个topic,多个producer,多个consumer的配置,使用。
