IBatis.NET连接MySQL数据库配置笔记

Software Version：IBatis.NET 1.6.2.0

MySQL :5.5.10

mysql-connector-net:6.4.3

visual studio 2010

-----------------------------------------------------------------------------------------------

首先在官网上下载IBatisNET的bin包http://www.mybatis.org/dotnet.html，在mysql官网上下载mysql-connection-net：http://dev.mysql.com/downloads/connector/net/，笔者选择的是“Windows
(x86, 32-bit), MSI Installer”版本。

以下是具体事例步骤：

1、将SqlMapConfig.xsd、SqlMap.xsd、provider.xsd三个文件Copy到“D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas”目录中，以便vs能够识别IBatis的一些属性

ps：“D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas”目录是VS的安装目录，请根据自己的目录自行解决。

2、新建一个Project，笔者新建的是WinForm项目。

3、将“Ibatis.DataMapper.1.6.2.bin”目录下的IBatisNet.DataMapper.dll、IBatisNet.Common.dll两个文件copy到项目中。





并且添加到引用里面。

ps：以上两个dll文件是否必须添加到项目中有待论证。

4、将“Ibatis.DataMapper.1.6.2.bin”目录下的providers.config复制到项目中，并且把除MySql以外的其他provider的enabled属性设置为false，MySql的enabled属性设置为true：

<provider
name="MySql"
description="MySQL, MySQL provider 6.4.3.0"
enabled="true"
assemblyName="MySql.Data, Version=6.4.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionClass="MySql.Data.MySqlClient.MySqlConnection"
commandClass="MySql.Data.MySqlClient.MySqlCommand"
parameterClass="MySql.Data.MySqlClient.MySqlParameter"
parameterDbTypeClass="MySql.Data.MySqlClient.MySqlDbType"
parameterDbTypeProperty="MySqlDbType"
dataAdapterClass="MySql.Data.MySqlClient.MySqlDataAdapter"
commandBuilderClass="MySql.Data.MySqlClient.MySqlCommandBuilder"
usePositionalParameters="false"
useParameterPrefixInSql="true"
useParameterPrefixInParameter="true"
parameterPrefix="?"
allowMARS="false"
/>

 

ps：注意version的版本号匹配。

5、“Ibatis.DataMapper.1.6.2.bin”目录下的sample.SqlMap.config文件复制到项目中，改名为SqlMap.config（不是必须的）。内容如下：

<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig
xmlns="http://ibatis.apache.org/dataMapper"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<settings>
<setting useStatementNamespaces="false"/>
<setting cacheModelsEnabled="true"/>
</settings>

<providers resource="..\..\providers.config"/>

<database>
<provider name="MySql"/>
<dataSource name="mybatisSource"
connectionString="Host=localhost;
UserName=root;
Password=123;
Database=mybatis;
Port=3306;" />
</database>

<sqlMaps>
<sqlMap resource="..\..\User.xml"/>
</sqlMaps>

</sqlMapConfig>

6、添加Mapper文件User.xml

<?xml version="1.0" encoding="utf-8" ?>
<sqlMap namespace="User"
xmlns="http://ibatis.apache.org/mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<alias>
<typeAlias alias="User" type="MybatisTest.User,MybatisTest" />
</alias>

<statements>
<insert id="InsertUser" parameterClass="User">
INSERT INTO user
(id, name)
VALUES
(#Id#,#Name#)
</insert>

<select id="SelectUser" parameterClass="int" resultMap="select_user_result">
SELECT
id
,name
FROM user
WHERE
id = #value#
</select>

<select id="SelectUserList" parameterClass="int" resultMap="select_user_result">
SELECT
id
,name
FROM user
</select>

<update id="update_user" parameterClass="User">
UPDATE user set
name = #Name#
WHERE
id = #Id#
</update>

</statements>
<resultMaps>
<resultMap id="select_user_result" class="User">
<result property="Id" column="id"/>
<result property="Name" column="name"/>
</resultMap>
</resultMaps>
</sqlMap>

 

7、实现程序：

 

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Configuration;
using IBatisNet.DataMapper.Configuration;
using IBatisNet.DataMapper;

namespace MybatisTest
{
public partial class Form1 : Form
{
private static ISqlMapper mapper;
public Form1()
{
InitializeComponent();
InitMapper();
}

public void InitMapper()
{
DomSqlMapBuilder builder = new DomSqlMapBuilder();
mapper = builder.Configure("..\\..\\SqlMap.config");
}

private void InsertButton_Click(object sender, EventArgs e)
{
string id = this.IDTextBox.Text.Equals("") ? "0" : this.IDTextBox.Text;
User user = new User()
{
Id = int.Parse(id),
Name = this.NameTextBox.Text,
};
try
{
mapper.Insert("InsertUser", user);
MessageBox.Show(this, "Insert success!", "Tips"
, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error"
, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

private void SelectButton_Click(object sender, EventArgs e)
{
if (this.IDTextBox.Text.Equals("") == true)
{
MessageBox.Show(this, "The id is null,please input a number!", "Tips"
, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
int id = int.Parse(this.IDTextBox.Text);
User user = mapper.QueryForObject("SelectUser", id) as User;

this.ResultLabel.Text = "Result is :\nid:" + user.Id.ToString()
+ "\nname:" + user.Name;
}
}

private void SelectListButton_Click(object sender, EventArgs e)
{
List<User> users = mapper.QueryForList<User>("SelectUserList", null) as List<User>;
this.ResultLabel.Text = "Result is :\n";
foreach (User user in users)
{
this.ResultLabel.Text += "id:" + user.Id.ToString()
+ "\nname:" + user.Name+"\n";
}
}

private void UpdateButton_Click(object sender, EventArgs e)
{
string id = this.IDTextBox.Text.Equals("") ? "0" : this.IDTextBox.Text;
User user = new User()
{
Id = int.Parse(id),
Name = this.NameTextBox.Text,
};

try
{
int result = mapper.Update("update_user", user);
if (result > 0)
{
MessageBox.Show(this, "Update success!", "Tips"
, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
MessageBox.Show(this, "Update failed!", "Tips"
, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error"
, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
}
}

 

界面设计如下：





ps：MySQL中需要手动创建数据库mybatis，以及表user
