DDD~WCF做中间件，实现多个项目的缓存共享

回到目录

事情是这样的，前台网站有些数据不希望每次都从数据库里读，所以，应该做个缓存，而引起缓存更新的入口来自网站的后台管理，而前台和后台被部署在不同的网站中，这时缓存的更新就成了问题，前台的缓存与后台的操作不能联系到一起，为了解决这个问题，我引入了WCF作为中间件，所以与数据库的操作，读，写都来自一个入口，那就是WCF，WCF用户告诉你是否从缓存取数据，所有缓存的数据也缓存在WCF中，OK，想法不错，下面来说一下具体的实现步骤。

一 首先看一下结构图：

注意看我的结构图，前台aop_cache和后台aop_cache_background项目都引用aop_cache_webservice项目，而它们没有对数据层aop_cache_data的引用，这个aop_cache_webservice是一个WCF项目，主要实现与数据层的通讯工作，当然也可以与BLL业务层通讯，这个架构主要是讲如何实现前后台共享缓存，而并非讲架构，所以重要不再架构，而在实现共享缓存。

二 WCF层实现所需要的DLL，主要是unity,cache,interception,log4net等，如图：

三 对于unity,wcf,cache的调用上，我进行了二次封装，如图：

aaarticlea/png;base64,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" alt="" />

四 看了这些，我们再来看一下，WEB层调用WCF层的代码片断：

        public ActionResult Index()
        {
            //  通过WCF获取远程数据,不走缓存, 走config中的<system.serviceModel>
            using (ServiceProxy<IService1> proxy = new ServiceProxy<IService1>())
            {
                return View(proxy.Channel.GetClassroom_Info());
            }
        }

web层的配置文件包含了对WCF的调用

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="ServiceProxyBinding" sendTimeout="00:10:00" receiveTimeout="00:10:00" closeTimeout="00:10:00"></binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint name="IService1" address="http://www.aop.com/Service1.svc" contract="aop_cache_WebService.IService1" binding="basicHttpBinding" bindingConfiguration="ServiceProxyBinding" />
    </client>
  </system.serviceModel>

五 WCF层调用DAL层的代码，使用unity来做方法拦截与依赖注入，将cache功能注入到指定方法中

        IClassroom_InfoRepository _iClassroom_InfoRepository = ServiceLocator.Instance.GetService<IClassroom_InfoRepository>();
        public void InsertClassroom_Info(Classroom_Info entity)
        {
            _iClassroom_InfoRepository.InsertClassroom_InfoData(entity);
        }

        public List<Classroom_Info> GetClassroom_Info()
        {
            return _iClassroom_InfoRepository.GetClassroom_InfoData();
        }

六 对于WCF的配置文件，我们要重要看一下，它包含了数据库连接串的配置和unity的配置

七 DAL层的实现，由接口和实现两部分组成，接口的方法上规定了是否要进行cache操作

   public interface IClassroom_InfoRepository
    {
        [Caching(CachingMethod.Remove, "GetClassroom_InfoData")]
        void InsertClassroom_InfoData(Classroom_Info entity);
        [Caching(CachingMethod.Get)]
        List<Classroom_Info> GetClassroom_InfoData();
    }

实现很简单，只是一个测试而以

   public class Classroom_InfoRepository : TsingDa_NewLearningBarRepository<Classroom_Info>, IClassroom_InfoRepository
    {
        public void InsertClassroom_InfoData(Classroom_Info entity)
        {
            base.Insert(entity);
        }
        public List<Classroom_Info> GetClassroom_InfoData()
        {
            return base.GetModel().ToList();
        }
    }
