基于EF+WCF的通用三层架构 含解析 附源码

本项目结合EF 4.3及WCF实现了经典三层架构，各层面向接口，WCF实现SOA，Repository封装调用，在此基础上实现了WCFContext，动态服务调用及一个分页的实例。

项目架构:

在传统的三层架构上增加了WcfService（服务端），WcfClientProxy（客户端服务调用），及WcfExtension（一些扩展）

• 工厂实现了RemoteServiceFactory（用于远程调用）和RefServiceFactory（本地引用调用服务层）生成客户端代理，都需要实现IServiceFactory的“IService CreateService();”
• RemoteServiceFactory通过ChannelFactory动态产生客户端代理类IService，并将此对象进行缓存
• WCFExtension实现了WCFContext，可传输用户登陆或IP上下文信息，以及拦截方法写Log的机制

 

数据层Repository的实现：

View Code 
 public class DaoBase : IRepository, IDisposable
     {
         public DbContext context;
 
         public DaoBase()
         {
             this.context = new EasyEF.DAL.DbContext();
         }
 
         public T Update<T>(T entity) where T : class
         {
             var set = context.Set<T>();
             set.Attach(entity);
             context.Entry<T>(entity).State = EntityState.Modified;
             context.SaveChanges();
 
             return entity;
         }
 
         public T Insert<T>(T entity) where T : class
         {
             context.Set<T>().Add(entity);
             context.SaveChanges();
             return entity;
         }
 
         public void Delete<T>(T entity) where T : class
         {
             context.Entry<T>(entity).State = EntityState.Deleted;
             context.SaveChanges();
         }
 
         public T Find<T>(params object[] keyValues) where T : class
         {
             return context.Set<T>().Find(keyValues);
         }
 
         public List<T> FindAll<T>(Expression<Func<T, bool>> conditions = null) where T : class
         {
             if (conditions == null)
                 return context.Set<T>().ToList();
             else
                 return context.Set<T>().Where(conditions).ToList();
         }
 
         public PagedList<T> FindAllByPage<T, S>(Expression<Func<T, bool>> conditions, Expression<Func<T, S>> orderBy, int pageSize, int pageIndex) where T : class
         {
             var queryList = conditions == null ? context.Set<T>() : context.Set<T>().Where(conditions) as IQueryable<T>;
 
             return queryList.OrderByDescending(orderBy).ToPagedList(pageIndex, pageSize);
         }
 
         public void Dispose()
         {
             this.context.Dispose();
         }
