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
