Active MQ C#完结

Active MQ
C#实现 

 

内容大致

C#,关键以源码的格局介绍怎么样用C#心想事成同Active MQ
的报纸发表。本文假如你已经正确安装JDK1.6.x,通晓Active
MQ并有肯定的编程基础。

正文

    JMS 程序的尾声目标是生产和消费的音讯能被其余程序行使,JMS 的 Message
是一个既简便易行又不乏灵活性的要旨格式,允许创设差别平台上符合非JMS
程序格式的音讯。

Message 由新闻头,属性和音信体三部份组成。

    Active
MQ援助过滤机制,即生产者可以安装消息的性质(Properties),该属性与消费者端的Selector对应,唯有消费者设置的selector与音信的Properties匹配,音讯才会发给该顾客。Topic和Queue都支持Selector。

/*
 * 功能描述:C#使用ActiveMQ示例
 * 修改次数:2
 * 最后更新: by Kagula,2012-07-31
 * 
 * 前提条件:
 * [1]apache-activemq-5.4.2
 * [2]Apache.NMS.ActiveMQ-1.5.6-bin
 * [3]WinXP SP3
 * [4]VS2008 SP1
 * [5]WPF工程 With .NET Framework 3.5
 * 
 * 启动
 *  
 * 不带安全控制方式启动
 * [你的解压路径]\apache-activemq-5.4.2\bin\activemq.bat
 * 
 * 安全方式启动
 * 添加环境变量:            ACTIVEMQ_ENCRYPTION_PASSWORD=activemq
 * [你的解压路径]\apache-activemq-5.4.2\bin>activemq xbean:file:../conf/activemq-security.xml
 * 
 * Active MQ 管理地址
 * http://127.0.0.1:8161/admin/
 * 添加访问"http://127.0.0.1:8161/admin/"的限制
 * 
 * 第一步:添加访问限制
 * 修改D:\apache\apache-activemq-5.4.2\conf\jetty.xml文件
 * 下面这行编码,原
 * <property name="authenticate" value="true" />
 * 修改为
 * <property name="authenticate" value="false" />
 * 
 * 第二步:修改登录用户名密码,缺省分别为admin,admin
 * D:\apache\apache-activemq-5.4.2\conf\jetty-realm.properties
 * 
 * 用户管理(前提:以安全方式启动ActiveMQ)
 * 
 * 在[你的解压路径]\apache-activemq-5.4.2\conf\credentials.properties文件中修改默认的用户名密码
 * 在[你的解压路径]\apache-activemq-5.4.2\conf\activemq-security.xml文件中可以添加新的用户名
 * e.g.  添加oa用户,密码同用户名。
 * <authenticationUser username="oa" password="oa" groups="users,admins"/>
 * 
 * 在[你的解压路径]\apache-activemq-5.4.2\conf\activemq-security.xml文件中你还可以设置指定的Topic或Queue
 * 只能被哪些用户组read 或 write。
 * 
 * 
 * 配置C# with WPF项目
 * 项目的[Application]->[TargetFramework]属性设置为[.NETFramework 3.5](这是VS2008WPF工程的默认设置)
 * 添加[你的解压路径]\Apache.NMS.ActiveMQ-1.5.6-bin\lib\Apache.NMS\net-3.5\Apache.NMS.dll的引用
 * Apache.NMS.dll相当于接口
 * 
 * 如果是以Debug方式调试
 * 把[你的解压路径]\Apache.NMS.ActiveMQ-1.5.6-bin\build\net-3.5\debug\目录下的
 * Apache.NMS.ActiveMQ.dll文件复制到你项目的Debug目录下
 * Apache.NMS.ActiveMQ.dll相当于实现
 * 
 * 如果是以Release方式调试
 * 参考上文,去取Apache.NMS,Release目录下相应的DLL文件,并复制到你项目的Release目录下。
