IBatis.NET連線MySQL資料庫配置筆記

Software Version：IBatis.NET 1.6.2.0
MySQL :5.5.10
mysql-connector-net:6.4.3
visual studio 2010
-----------------------------------------------------------------------------------------------
以下是具體事例步驟：
1、將SqlMapConfig.xsd、SqlMap.xsd、provider.xsd三個檔案Copy到“D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas”目錄中，以便vs能夠識別IBatis的一些屬性
ps：“D:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas”目錄是VS的安裝目錄，請根據自己的目錄自行解決。
2、新建一個Project，筆者新建的是WinForm專案。
3、將“Ibatis.DataMapper.1.6.2.bin”目錄下的IBatisNet.DataMapper.dll、IBatisNet.Common.dll兩個檔案copy到專案中。
並且新增到引用裡面。
ps：以上兩個dll檔案是否必須新增到專案中有待論證。
4、將“Ibatis.DataMapper.1.6.2.bin”目錄下的providers.config複製到專案中，並且把除MySql以外的其他provider的enabled屬性設定為false，MySql的enabled屬性設定為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的版本號匹配。
5、“Ibatis.DataMapper.1.6.2.bin”目錄下的sample.SqlMap.config檔案複製到專案中，改名為SqlMap.config（不是必須的）。內容如下：
<?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、新增Mapper檔案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、實現程式：
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);
}
}
}
}
介面設計如下：
ps：MySQL中需要手動建立資料庫mybatis，以及表user
