Mybatis.net + Mysql

项目文件结构

NuGet下载Mybatis.net相关包：IBatisNet

安装完成后，会显示在，在已安装页面。同时，在管理器中的引用列表中，会多出来两个引用文件

IBatisNet.Common

IBatisNet.DataMapper

安装 Mysql.data。

注意：

安装完成后，在管理器中的引用列表中，会多出来一个引用文件：Mysql.Data文件

安装时，尽量不要选择太高的版本，否则有可能跟已有的.NET Framework 版本不匹配

创建三层机构

Model层

using System;

namespace HrSystem.Model
{
    /// <summary>
    /// 系统用户
    /// </summary>
    public class SysUser
    {
        // 主键id
        public int _id
        {
            get; set;
        }

        // 唯一编号
        public string _empNo
        {
            get; set;
        }

        // 用户名称
        public string _name
        {
            get; set;
        }

        // 密码
        public string _password
        {
            get; set;
        }

        // 联系电话
        public string _mobile
        {
            get; set;
        }

        // 邮件
        public string _email
        {
            get; set;
        }

        // 紧急联系人
        public string _urgentName
        {
            get; set;
        }

        // 紧急联系电话
        public string _urgentMobile
        {
            get; set;
        }

        // 头像地址Url
        public string _headUrl
        {
            get; set;
        }

        // 生日
        public DateTime _birthday
        {
            get; set;
        }

        // 工作状态:在职离职等【run_type_enum】
        public int _runType
        {
            get; set;
        }

        // 入职时间
        public DateTime _initTime
        {
            get; set;
        }

        // 备注
        public string _remark
        {
            get; set;
        }

        // 创建人工编号
        public string _createEmpNo
        {
            get; set;
        }

        // 创建时间
        public DateTime _createTime
        {
            get; set;
        }

        // 更新人工号
        public string _updateEmpNo
        {
            get; set;

        }

        // 更新时间
        public DateTime _updateTime
        {
            get; set;
        }


        public override string ToString()
        {
            return string.Format("[Mybatis: id={0}, name={1}]", _id, _name);
        }
    }
}

Mapper层（也叫DAO层）

using IBatisNet.DataMapper;
using System;

namespace HrSystem.Mappers
{
    public class MybatisMapper
    {
        /// <summary>
        /// Gets the entity mapper.
        /// </summary>
        /// <value>The entity mapper.</value>
        public static ISqlMapper EntityMapper
        {
            get
            {
                try
                {
                    ISqlMapper mapper = Mapper.Instance();
                    return mapper;
                }
                catch (Exception ex)
                {
                    Console.WriteLine("ex:{0}", ex);
                    throw ex;
                    //return null;
                }
            }
        }
    }
}

Service层

using System;
using System.Collections.Generic;
using HrSystem.Mappers;
using HrSystem.Model;
using IBatisNet.DataMapper;
namespace mybatisNet

    public class UserService
    {

            }
        }

                return result;
            }
            catch (Exception ex)
            {

                return null;

            try
            {
                int result = mapper.Update("UpdateMybatis", mybatis);
                return result;
            }
            catch (Exception ex)
            {
                Console.WriteLine("ex:{0}", ex);
                return 0;
            }
        }

        /// <summary>

        public int DeleteMybatis(SysUser mybatis)
        {
            ISqlMapper mapper = MybatisMapper.EntityMapper;
            try

                int result = mapper.Delete("DeleteMybatis", mybatis);
                return result;
            }
            catch (Exception ex)
            {
                Console.WriteLine("ex:{0}", ex);
                return 0;
            }
        }


        /// <summary>

        public IList<SysUser> GetList()
        {
            ISqlMapper mapper = MybatisMapper.EntityMapper;
            IList<SysUser> listBlogContent = mapper.QueryForList<SysUser>("selectAllContent", null);
            return listBlogContent;
        }
    }
}

Controller层（应用层）

using HrSystem.Model;
using mybatisNet;
using System;

namespace HrSystem.Forms.UserForms
{
    public class DealUserSql
    {
        public static SysUser GetUserDetailByEmpNo(string businessId)
        {
            //string sql_str = "select * from sys_user where emp_no = '" + businessId + "';";
            //Console.WriteLine(sql_str);

            //return GlobalMysql.GetOneUser(sql_str, true);


            UserService service = new UserService();
            //Mybatis mybatis = new Mybatis();
            //mybatis.Id = 3;
            //mybatis.Name = "hello mybatis .net update";
            //service.InsertMybatis(mybatis);
            //service.Q
            //service.UpdateMybatis(mybatis);
            //service.DeleteMybatis(mybatis);
            Console.WriteLine("result: {0}", service.QueryMybatis(1));

            return null;

        }




    }
}

创建配置文件

右键项目 -> 添加 -> 新建项

映射层Mapper.xml

配置属性
