iBatis for net 框架使用
生活随笔
收集整理的這篇文章主要介紹了
iBatis for net 框架使用
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
簡介：ibatis?一詞來源于“internet”和“abatis”的組合，是一個由Clinton?Begin在2001年發起的開放源代碼項目，到后面發展的版本叫MyBatis但都是指的同一個東西。最初側重于密碼軟件的開發，現在是一個基于Java的持久層框架，漸漸的也把這種模式轉移到了net。相對NHibernate等“一站式”ORM解決方案而言，ibatis?是一種“半自動化”的ORM實現。

本文開發Demo環境：IBatis.DataMapper.1.6.2.bin?+?MsSql?2005?+?Vs?2010
使用步驟：
在使用之前，為大家推薦一款代碼生成器，也是我專為此框架寫的一款代碼生成器，生成iBatis的Map配置文件，這樣一來，用戶不用開任何關于框架的說明文檔，即可使用此框架。代碼生成器（CodeHelper）下載地址與說明：
http://www.cnblogs.com/stone_w/archive/2011/09/26/2192010.html?
第一步：創建數據庫與新建網站項目。
創建數據庫與表的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
打開vs開發工具，新建網站項目。
第二步：為網站添加iBatis框架支持。
為網站添加引用或者直接把下載的iBatis框架中的IBatisNet.Common.dll和IBatisNet.DataMapper.dll復制到Bin目錄下。
第三步：添加iBatis配置文件。
iBatis的配置文件只用三種，也必須要有這三種：
1.providers.config[文件名不能修改]此文件為數據庫開發商提供的驅動配置集合，是固定不變的，無需修改與配置，復制文件到網站的根目錄，代碼如下：
providers.config <?xml version="1.0" encoding="utf-8"?><providers

</providers>
2.SQLMap.config[文件名不可修改]，配置連接數據庫字符串與每個實體類（表）的映射文件配置，復制文件到網站的根目錄，代碼如下：
<?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命名空間，這里的命名空間指的是映射文件中sqlMap節點的namespace屬性，默認是false-->
????????<setting?useStatementNamespaces="false"/>
????????<!--是否啟用DataMapper的緩存機制,針對全部的SqlMap，默認是true-->
????????<setting?cacheModelsEnabled="true"/>
????????<!--是否啟用SqlMapConfig.xsd?schema驗證映射文件，默認是false-->
????????<setting?validateSqlMap="false"/>
????</settings>
????<!--配置數據驅動提供類配置文件的路徑和文件名-->
????<providers?resource="providers.config"/>
????<!--如果在providers.config文件中指定了默認的數據庫驅動，那么provider節點就不需要設置了，它的作用是在換數據庫驅動時不需要修改providers.config文件。datasource節點用于指定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.每個實體類（表）都有一個單獨的配置文件類，類型為xml。代碼生成器也是生成這個類的，這樣一來，用戶就可以幾秒鐘創建開發一個iBatis項目了，實體類的配置文件格式如下，在網站的根目錄創建一個Map的文件夾，新建xxxMap.xml格式的配置類，比如：PeopleMap.xml文件，示例代碼如下：
<?xml?version="1.0"?encoding="utf-8"??>
<!--namespace必須用否者就報錯（讀取配置文件報：未將對象引用設置到對象的實例）-->
<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>
這三類配置文件必須都要有，與其他orm框架不同的是，web.config什么也不用配置，及時練數據庫連接字符串也不是在它的文件中配置的，也就是web.config是沒有被用到的。
第四步：iBatis框架語法與使用。

}
else if (iCount > PageSize * curPage)
{
break;
}
iCount++; // 臨時記錄變量遞增
}
if (!dataReader.IsClosed)
{
dataReader.Close();
dataReader.Dispose();
}
return dt;
}
}
使用語法如下：
//?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]大小寫要和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.刪除
IBatisHepler.ExcuteDelete("Delete",?14);
//?4.查詢
Repeater1.DataSource?=?IBatisHepler.ExcuteSelectObj("GetPeopleById",?"1");
Repeater1.DataBind();
我對此框架的評價：配置文件有點多，用戶需要去寫東西比較多，調用查詢不是很好用，尤其是條件查詢很不方便。
