简介：ibatis 一词来源于“internet”和“abatis”的组合，是一个由Clinton Begin在2001年发起的开放源代码项目，到后面发展的版本叫MyBatis但都是指的同一个东西。最初侧重于密码软件的开发，现在是一个基于Java的持久层框架，渐渐的也把这种模式转移到了net。相对NHibernate等“一站式”ORM解决方案而言，ibatis 是一种“半自动化”的ORM实现。

本文开发Demo环境：IBatis.DataMapper.1.6.2.bin + MsSql 2005 + Vs 2010
使用步骤：
在使用之前，为大家推荐一款代码生成器，也是我专为此框架写的一款代码生成器，生成iBatis的Map配置文件，这样一来，用户不用开任何关于框架的说明文档，即可使用此框架。代码生成器（CodeHelper）下载地址与说明：

第一步：创建数据库与新建网站项目。
创建数据库与表的T-sql：
/*
* iBatisDemo Sql
* Stone (QQ:1370569)
* Date:2011.09.26
*/
create database OrmDB
go
use OrmDB
go
create table People
(
id int primary key identity,
[name] varchar(250),
age int
)
go
打开vs开发工具，新建网站项目。
第二步：为网站添加iBatis框架支持。
为网站添加引用或者直接把下载的iBatis框架中的IBatisNet.Common.dll和IBatisNet.DataMapper.dll复制到Bin目录下。
第三步：添加iBatis配置文件。
iBatis的配置文件只用三种，也必须要有这三种：
1.providers.config[文件名不能修改]此文件为数据库开发商提供的驱动配置集合，是固定不变的，无需修改与配置，复制文件到网站的根目录，代码如下：

2.SQLMap.config[文件名不可修改]，配置连接数据库字符串与每个实体类（表）的映射文件配置，复制文件到网站的根目录，代码如下：
<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig
xmlns="http://ibatis.apache.org/dataMapper"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<settings>
<!--/是否使用Satement命名空间，这里的命名空间指的是映射文件中sqlMap节点的namespace属性，默认是false-->
<setting useStatementNamespaces="false"/>
<!--是否启用DataMapper的缓存机制,针对全部的SqlMap，默认是true-->
<setting cacheModelsEnabled="true"/>
<!--是否启用SqlMapConfig.xsd schema验证映射文件，默认是false-->
<setting validateSqlMap="false"/>
</settings>
<!--配置数据驱动提供类配置文件的路径和文件名-->
<providers resource="providers.config"/>
<!--如果在providers.config文件中指定了默认的数据库驱动，那么provider节点就不需要设置了，它的作用是在换数据库驱动时不需要修改providers.config文件。datasource节点用于指定ADO.NET Connection String.-->
<database>
<provider name="sqlServer2.0"/>
<dataSource name="mydb" connectionString="data source=127.0.0.1;database=MyBatisDB;user id=sa;password=sa;"/>
</database>
<!--指定映射的文件的位置-->
<sqlMaps>
<sqlMap resource="Maps/PeopleMap.xml"/>
</sqlMaps>
</sqlMapConfig>
3.每个实体类（表）都有一个单独的配置文件类，类型为xml。代码生成器也是生成这个类的，这样一来，用户就可以几秒钟创建开发一个iBatis项目了，实体类的配置文件格式如下，在网站的根目录创建一个Map的文件夹，新建xxxMap.xml格式的配置类，比如：PeopleMap.xml文件，示例代码如下：
<?xml version="1.0" encoding="utf-8" ?>
<!--namespace必须用否者就报错（读取配置文件报：未将对象引用设置到对象的实例）-->
<sqlMap namespace="" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<statements>
<select id="GetPeopleById" parameterClass="string" resultClass="HashTable">
SELECT * FROM People WHERE Id=#Id#
</select>
<insert id="Add" parameterClass="hashtable">
INSERT dbo.People (name ,age)
VALUES (#Name# , #Age#)
</insert>
<delete id="Delete" parameterClass="int" restultClass="int">
DELETE FROM dbo.People WHERE Id=#Id#
</delete>
<update id="Update" parameterClass="hashtable" restltClass="int">
UPDATE People SET name=#Name# WHERE Id=#Id#
</update>
<select id="GetAll" resultClass="HashTable">
SELECT * FROM People
</select>
</statements>
</sqlMap>
这三类配置文件必须都要有，与其他orm框架不同的是，web.config什么也不用配置，及时练数据库连接字符串也不是在它的文件中配置的，也就是web.config是没有被用到的。
第四步：iBatis框架语法与使用。
使用之前先来加入一个DB辅助类IBatisHepler.cs，代码如下：
IBatisHepler.cs using System;using System.Collections.Generic;using System.Text;using IBatisNet.DataMapper.Configuration.Statements;using IBatisNet.DataMapper;using IBatisNet.DataMapper.MappedStatements;using IBatisNet.Common;using IBatisNet.DataMapper.Scope;using System.Data;using IBatisNet.DataMapper.Configuration;using System.Collections;/// <summary>/// IBatis 使用工具类/// </summary>public class IBatisHepler{ private static ISqlMapper mapper = null; static IBatisHepler() { DomSqlMapBuilder builder = new DomSqlMapBuilder();//其作用是根据配置文件创建SqlMap实例。 mapper = builder.Configure("SqlMap.config") as SqlMapper;//SqlMapper是iBatisNet的核心组件，提供数据库操作的基础平台。SqlMapper可通过DomSqlMapBuilder创建。 } /// <summary> /// 执行添加操作 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>添加的主键</returns> public static object ExcuteInsert(string tag, Hashtable paramObject) { return mapper.Insert(tag, paramObject); } /// <summary> /// 执行删除操作 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>影响行数</returns> public static int ExcuteDelete(string tag, object paramObject) { return mapper.Delete(tag, paramObject); } /// <summary> /// 执行修改操作 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>影响行数</returns> public static int ExcuteUpdate(string tag, Hashtable paramObject) { return mapper.Update(tag, paramObject); } /// <summary> /// 查询单个实体对象 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>得到的Object</returns> public static object ExcuteSelectObj(string tag, object paramObject) { object obj = mapper.QueryForObject(tag, paramObject); return obj; } /// <summary> /// 分页查询 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <param name="pageIndex">页索引</param> /// <param name="pageSize">每页显示的记录数</param> /// <returns>得到的List集合</returns> public static IList ExcuteSelect(string tag, object paramObject, int pageIndex, int pageSize) { return mapper.QueryForList(tag, paramObject, pageIndex, pageSize); } /// <summary> /// 通用的以DataTable的方式得到Select的结果(xml文件中参数要使用$标记的占位参数) /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>得到的DataTable</returns> public static DataTable ExcuteSelect(string tag, object paramObject) { DataSet ds = new DataSet(); bool isSessionLocal = false; ISqlMapSession session = mapper.LocalSession; if (session == null) { session = mapper.CreateSqlMapSession(); session.OpenConnection(); isSessionLocal = true; } try { IDbCommand cmd = session.CreateCommand(CommandType.Text); cmd.Connection = session.Connection; cmd.CommandText = GetSql(tag, paramObject); IDbDataAdapter adapter = session.CreateDataAdapter(cmd); adapter.Fill(ds); } finally { if (isSessionLocal) { session.CloseConnection(); } } return ds.Tables[0]; } /// <summary> /// 得到参数化后的SQL /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <returns>sql语句</returns> protected static string GetSql(string tag, object paramObject) { IStatement statement = mapper.GetMappedStatement(tag).Statement; IMappedStatement mapStatement = mapper.GetMappedStatement(tag); ISqlMapSession session = mapper.CreateSqlMapSession(); RequestScope request = statement.Sql.GetRequestScope(mapStatement, paramObject, session); return request.PreparedStatement.PreparedSql; } /// <summary> /// 用于分页控件使用 /// </summary> /// <param name="tag">语句ID</param> /// <param name="paramObject">语句所需要的参数</param> /// <param name="PageSize">每页显示数目</param> /// <param name="curPage">当前页</param> /// <param name="recCount">记录总数</param> /// <returns>得到的DataTable</returns> public static DataTable ExcuteSelect(string tag, object paramObject, int PageSize, int curPage, out int recCount) { IDataReader dr = null; bool isSessionLocal = false; string sql = GetSql(tag, paramObject); string strCount = "select count(*) " + sql.Substring(sql.ToLower().IndexOf("from")); IDalSession session = mapper.LocalSession; DataTable dt = new DataTable(); if (session == null) { session = mapper.CreateSqlMapSession(); session.OpenConnection(); isSessionLocal = true; } try { IDbCommand cmdCount = session.CreateCommand(CommandType.Text); cmdCount.Connection = session.Connection; cmdCount.CommandText = strCount; object count = cmdCount.ExecuteScalar(); recCount = Convert.ToInt32(count); IDbCommand cmd = session.CreateCommand(CommandType.Text); cmd.Connection = session.Connection; cmd.CommandText = sql; dr = cmd.ExecuteReader(); dt = Paging(dr, PageSize, curPage); } finally { if (isSessionLocal) { session.CloseConnection(); } } return dt; } /**/ /// <summary> /// 取回合适数量的数据 /// </summary> /// <param name="dataReader"></param> /// <param name="PageSize"></param> /// <param name="curPage"></param> /// <returns></returns> protected static DataTable Paging(IDataReader dataReader, int PageSize, int curPage) { DataTable dt; dt = new DataTable(); int colCount = dataReader.FieldCount; for (int i = 0; i < colCount; i++) { dt.Columns.Add(new DataColumn(dataReader.GetName(i), dataReader.GetFieldType(i))); } // 读取数据。将DataReader中的数据读取到DataTable中 object[] vald = new object[colCount]; int iCount = 0; // 临时记录变量 while (dataReader.Read()) { // 当前记录在当前页记录范围内 if (iCount >= PageSize * (curPage - 1) && iCount < PageSize * curPage) { for (int i = 0; i < colCount; i++) vald[i] = dataReader.GetValue(i); dt.Rows.Add(vald); } else if (iCount > PageSize * curPage) { break; } iCount++; // 临时记录变量递增 } if (!dataReader.IsClosed) { dataReader.Close(); dataReader.Dispose(); } return dt; }}
使用语法如下：
// 添加引用
using System.Collections;
using IBatisNet.DataMapper;
using IBatisNet.DataMapper.Configuration;
// 1.添加
Hashtable ht_add = new Hashtable();
ht_add["Name"] = "IBatis"; // [注意]大小写要和xxxMap.xml里保持一致
ht_add["Age"] = 2001;
IBatisHepler.ExcuteInsert("Add", ht_add);
// 2.修改
Hashtable ht_up = new Hashtable();
ht_up["Id"] = "1";
ht_up["Name"] = "IBatis";
ht_up["Age"] = 2001;
IBatisHepler.ExcuteUpdate("Update", ht_up);
// 3.删除
IBatisHepler.ExcuteDelete("Delete", 14);
// 4.查询
Repeater1.DataSource = IBatisHepler.ExcuteSelectObj("GetPeopleById", "1");
Repeater1.DataBind();
我对此框架的评价：配置文件有点多，用户需要去写东西比较多，调用查询不是很好用，尤其是条件查询很不方便。
