- 消息处理
- 首先需要创建“处理器”，用ActiveMessaging的术语来说，就是一个支持消息目标者有序接收和处理消息的类。它在设计模型中是必不可少，相当于消息驱动的控制器，代码量也占最大比例。
- 3 more annotations...
- - 下面，我们具体讨论上述各行输出结果的含义。
    
    app/processors：全部处理器所在目录。
    app/processors/persist_message_processor.rb：按缺省配置生成的新处理器。
    app/processors/application.rb：供新处理器继承的通用超类。它实现了一些通用功能，如错误处理。
    config/broker.yml：代理配置，指明了连接消息代理的方法。类似database.yml，但它是用于消息代理的。
    config/messaging.rb：消息传输用到的其他配置，如目的地、消息头。
    script/poller：ActiveMessaging用以监听消息的后台程序。后文对此还有说明。
  - class PersistMessageProcessor < ApplicationProcessor
    subscribes_to :persist_message
    def on_message(message)
    logger.debug "PersistMessageProcessor received: " + message
    end
    end
  - 上述代码实现了:persist_message消息的订阅，并指定了方法on_message。当:persist_message消息到来时，ActiveMessaging将回调on_message。参数message负责按字符串格式传递消息内容；依靠@message，还可以直接访问Stomp消息对象。通过再次调用subscribes_to，处理器可以订阅更多消息

- Messaging Oriented Middleware(MOM)
- 3 more annotations...
- - <meta http-equiv='refresh' content='2'/>
  - 在 HTML HEAD 中我加入了一句 META REFRESH，目的是定期更新页面，模拟真实股价更新的情况
  - 这同样取自 AMQ，主要是 amq.addListener('stocks','/topic/STOCKS.*',priceHandler._price);，这让 browser 当收到由 /topic/STOCKS.* 传来的讯息时会执行指定的 javascript 更新画面。

- he architecture in my mind is that an rails application for account
  management(credentials,credits,etc) and rest api and using
  activemessaging for message distribution. there will be as many as
  queues for each distrubtion type (eg sms queue, email queue). when a
  request comes, the controller will send the message to the appropriate
  queue. A processor will get the message from the queue, parses it and
  runs the logic to deliver it.
- Absolutely - should work great. You can scale the processors seprately that
  way, so if you end up getting 10 times as many sms messages to send than
  email messages, you can start more pollers just listening to the sms queue.
  
  Only downside woud be if you had it so a single request should be pushed out
  to both SMS and email for example. Then you would need to put 2 messages
  out for theone request - again, not a big deal probably, just trying to
  think if there is any real downside.
