  • 【无私分享:从入门到精通ASP.NET MVC】从0开始,一起搭框架、做项目 (15)源码分享一:修改仓储IRepository、RepositoryBase

    索引

    【无私分享:从入门到精通ASP.NET MVC】从0开始,一起搭框架、做项目 目录索引

    简述

     

    前言:

    从今天开始,我们逐步把修正前后的源码分享给大家,还是百度网盘分享,百度网盘只发两次,两次都失效后,请大家互相传递。

    数据库,已经在上一章发布完成的项目中给大家了,这里不再重复发送数据库。

    今天,分享的是修改前后的仓储IRepository、RepositoryBase

    修改前弊端:

      如果大家仔细看过之前的仓储IRepository、RepositoryBase,那么大家肯定会发现,这个类无论是在效率上还是逻辑上,还是有很多不合适、不合理的。我本来是想在 【无私分享:ASP.NET CORE 项目实战】目录索引 系列中逐步修改,但是经过再三考虑,如果把这个源码直接给大家,对于刚接触的朋友实在是太不负责任,容易产生误导,所以,还是要在这里进行修正。

      在【无私分享:ASP.NET CORE 项目实战(第五章)】Repository仓储 UnitofWork 这篇文章中,简单介绍了一下个人对于UnitOfWrok的理解,虽然 EF 是自带事务的,但是我们的 Context.SaveChanges() 无疑抛弃了统一的事务,同时,作为一个封装的仓储类,我们是应该提供 串行和并行 两种方式的,至于到底用不用异步方式,这个我们不能泛滥,异步不是没有损耗的,我们只是提供两种方式,到底用什么,要根据业务需要调用,而不是一味的异步方式,所有的东西都是过无不及。

    修正一:添加UnitOfWork

      这是我们之前的Service 类库:

      

    我们添加 IUnitOfWork 接口 和 UnitOfWork 实现类

     1 namespace Service
     2 {
     3     public interface IUnitOfWork
     4     {
     5         /// <summary>
     6         /// 提交
     7         /// </summary>
     8         /// <returns></returns>
     9         bool Commit();
    10 16     }
    17 }
     1     public class UnitOfWork : IUnitOfWork, IDisposable
     2     {
     3         #region 数据上下文
     4 
     5         private DbContext context = new MyConfig().db;
     6         /// <summary>
     7         /// 数据上下文
     8         /// </summary>
     9         public DbContext _Context
    10         {
    11             get
    12             {
    13                 context.Configuration.ValidateOnSaveEnabled = false;
    14                 return context;
    15             }
    16         }
    17 
    18         #endregion
    19 
    20         /// <summary>
    21         /// 提交
    22         /// </summary>
    23         /// <returns></returns>
    24         public bool Commit()
    25         {
    26             return _Context.SaveChanges() > 0;
    27         }
    28 
    29         public void Dispose()
    30         {
    31             if (_Context != null)
    32             {
    33                 _Context.Dispose();
    34             }
    35             GC.SuppressFinalize(this);
    36         }
    37     }

    修正二:修改IRepository

    首先,把涉及到事务的没用都删掉:

    修改单模型CRUD操作:①、增加异步方式 ②、添加 bool IsCommit = true 参数,判断是否提交

    这个参数的主要作用是,我们在进行单项操作的时候,可以直接提交保存,当进行多项操作的时候,我们这个传入False,然后 通过 UnitOfWork 统一提交保存

     1  #region 单模型 CRUD 操作
     2         /// <summary>
     3         /// 增加一条记录
     4         /// </summary>
     5         /// <param name="entity">实体模型</param>
     6         /// <param name="IsCommit">是否提交(默认提交)</param>
     7         /// <returns></returns>
     8         bool Save(T entity, bool IsCommit = true);
     9         /// <summary>
    10         /// 增加一条记录(异步方式)
    11         /// </summary>
    12         /// <param name="entity">实体模型</param>
    13         /// <param name="IsCommit">是否提交(默认提交)</param>
    14         /// <returns></returns>
    15         Task<bool> SaveAsync(T entity, bool IsCommit = true);
    16 
    17         /// <summary>
    18         /// 更新一条记录

    21         /// <param name="IsCommit">是否提交(默认提交)</param>
    22         /// <returns></returns>
    23         bool Update(T entity, bool IsCommit = true);

    29         /// <returns></returns>
    30         Task<bool> UpdateAsync(T entity, bool IsCommit = true);

     修改前的RepositoryBase:链接:http://pan.baidu.com/s/1pKYRIkF 密码:uj2u

     修改后的RepositoryBase:链接:http://pan.baidu.com/s/1o77PyVg 密码:gsdn

    修改后的代码,大家先不要直接替换掉项目中的RepositoryBase,我们的接口和实现类也需要做一些修改。我们在下一章,修改接口和实现类,改完后,可以直接覆盖掉。
