iBatis for net 框架使用

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。

下载地址：http://code.google.com/p/mybatisnet/downloads/list?can=3 

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：

http://www.cnblogs.com/stone_w/archive/2011/09/26/2192010.html 

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：

providers.config

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。

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。
