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
19         /// </summary>
20         /// <param name="entity">实体模型</param>
21         /// <param name="IsCommit">是否提交(默认提交)</param>
22         /// <returns></returns>
23         bool Update(T entity, bool IsCommit = true);
24         /// <summary>
25         /// 更新一条记录(异步方式)

28         /// <param name="IsCommit">是否提交(默认提交)</param>
29         /// <returns></returns>
30         Task<bool> UpdateAsync(T entity, bool IsCommit = true);
31

38         /// <returns></returns>

42         /// </summary>

48         
49         #endregion

 修改验证是否存在,同时增加异步方式:

 1 #region 验证是否存在
 2 
 3         /// <summary>
 4         /// 验证当前条件是否存在相同项
 5         /// </summary>

 8         /// 验证当前条件是否存在相同项(异步方式)

 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。
