ActiveMQ 是Apache出品,最流行的,能力强劲的开源消息总线。ActiveMQ 是一个完全支持JMS1.1和J2EE 1.4规范的 JMS Provider实现,尽管JMS规范出台已经是很久的事情了,但是JMS在当今的J2EE应用中间仍然扮演着特殊的地位。
特性列表:
⒈ 多种语言和协议编写客户端。语言: Java,C,C++,C#,Ruby,Perl,Python,PHP。应用协议: OpenWire,Stomp REST,WS Notification,XMPP,AMQP
⒉ 完全支持JMS1.1和J2EE 1.4规范 (持久化,XA消息,事务)
⒊ 对spring的支持,ActiveMQ可以很容易内嵌到使用Spring的系统里面去,而且也支持Spring2.0的特性
⒋ 通过了常见J2EE服务器(如 Geronimo,JBoss 4,GlassFish,WebLogic)的测试,其中通过JCA 1.5 resource adaptors的配置,可以让ActiveMQ可以自动的部署到任何兼容J2EE 1.4 商业服务器上
⒌ 支持多种传送协议:in-VM,TCP,SSL,NIO,UDP,JGroups,JXTA
⒍ 支持通过JDBC和journal提供高速的消息持久化
⒎ 从设计上保证了高性能的集群,客户端-服务器,点对点
⒏ 支持Ajax
⒐ 支持与Axis的整合
⒑ 可以很容易的调用内嵌JMS provider,进行测试
ActiveMq安装很简单,ActiveMQ默认启动到8161端口,启动完了后在浏览器地址栏输入:http://localhost:8161/admin 要求输入用户名密码,默认用户名密码为admin、admin,后便可看到ActiveMQ控制台界面了。
