我有以下spring-integration配置v1.0.4。

<bean id="emailReceiverService" class="com.mycompany.DefaultEmailReceiverUtilService">

DefaultEmailReceiverUtilService

public class DefaultEmailReceiverUtilService implements
        EmailReceiverUtilService
{

    public void receive(Message<?> message)
    {
        //Processing the emails
    }
}

问题:

  1. 是多线程的吗?或电子邮件将以连续方式处理?如果是,那么如何使其多线程?
  2. 当我的应用程序在eclipse调试模式下运行时,我可以看到一些Timer任务线程,但每个请求以顺序方式进入相同的计时器任务,我的线程数(Timer任务)也在稳步增长。我可能会误解它。
  3. 如果我错了,请纠正我。

我认为你需要的是队列频道。你的receiveEmailChannel应该是这样的:

<int:channel id="recieveEmailChannel">  
<int:queue/>
<int:interceptors>
    <int:wire-tap channel="logger"/>
</int:interceptors>
</int:channel>

我相信您会知道如何定义队列通道。您当前拥有的点对点通道是同步的,它一次只能传递1条消息。

目前,如果您要向该频道添加内容,它将等待服务激活器完成,而使用队列通道时,服务激活器应在检测到队列中的某个内容时立即触发新线程。
