C#代码生成器-基于MyBatis.NET

背景

编写代码生成器的目的是为了进一步减少程序员的重复性“体力劳动”，让程序员有更多的时间去做创造性的工作，提高编码的质量。我在编码和架构过程中层自己开发了一系列代码生成工具，本着开源和分享的目的，会在本期和后期博客中倾情奉献给有需要的朋友，不足指出也请多包含，因为共享源码，你也可以进行修改使用。

实现思路

预先编制模版，包括实体类、数据访问类、业务逻辑类、配置文件，基于已定义的数据库结构进行模版替换生成。

MyBatis.NET简介

MyBatis是业界非常优秀的ORM框架，可谓Java开发者必用的数据持久化框架。而MyBatis.NET其实就是使用C#对其进行翻版，可以让C#程序员用其简化数据访问的代码，从性能、轻量级、灵活度等角度看都比EntityFramework强不少，而且适合Java团队与C#团队的技术栈统一，便于不同语言的开发者转型。

关键模版代码

1、实体类模版（EntityClassTemplate.txt）

using System.Collections.Generic;
using System.Text;

namespace ${EntityNameSpace}
{
    /// <summary>
    /// 实体类${EntityClassName}
    /// </summary>
    [Serializable]
    public class ${EntityClassName}
    {
        #region 私有字段

${PrivateFields}

        #endregion

        #region 公有属性

${PublicAttribute}

        #endregion	
    }
}
