iBatis for net 框架使用

红太狼 2024-02-18 19:56 55阅读 0赞

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：

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

\*/

createdatabase OrmDB

use OrmDB

createtable People

(

id intprimarykeyidentity,

\[name\] varchar(250),

age int

)

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：

          parameterDbTypeClass="IBM.Data.Informix.IfxType"
          parameterDbTypeProperty="IfxType"
          dataAdapterClass="IBM.Data.Informix.IfxDataAdapter"
          commandBuilderClass="IBM.Data.Informix.IfxCommandBuilder"
          usePositionalParameters = "true"
          useParameterPrefixInSql = "false"
          useParameterPrefixInParameter = "false"
          useDeriveParameters="false"
          allowMARS="false"
        />
    </providers>

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：

<?xmlversion="1.0"encoding="utf-8"?>

<sqlMapConfig

xmlns="http://ibatis.apache.org/dataMapper"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<settinguseStatementNamespaces="false"/>

<settingcacheModelsEnabled="true"/>

<settingvalidateSqlMap="false"/>

</settings>

<providersresource="providers.config"/>

<providername="sqlServer2.0"/>

<dataSourcename="mydb"connectionString="data source=127.0.0.1;database=MyBatisDB;user id=sa;password=sa;"/>

</database>

<sqlMapresource="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][http_www.cnblogs.com_stone_w_archive_2011_09_26_2192010.html]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：

<?xmlversion="1.0"encoding="utf-8" ?>

<sqlMapnamespace=""xmlns="http://ibatis.apache.org/mapping"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<selectid="GetPeopleById"parameterClass="string"resultClass="HashTable">

SELECT \* FROM People WHERE Id=\#Id\#

</select>

<insertid="Add"parameterClass="hashtable">

INSERT dbo.People (name ,age)

VALUES (\#Name\# , \#Age\#)

</insert>

<deleteid="Delete"parameterClass="int"restultClass="int">

DELETE FROM dbo.People WHERE Id=\#Id\#

</delete>

<updateid="Update"parameterClass="hashtable"restltClass="int">

UPDATE People SET name=\#Name\# WHERE Id=\#Id\#

</update>

<selectid="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：

            }
            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 = newHashtable();

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 = newHashtable();

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。
