下载ibatis软件包（http://ibatis.apache.org/dotnetdownloads.html）。
2. 创建测试数据库，并在数据库中创建一个Person 表，其中包含三个字段：
Name Type Size
PER_ID Long Integer 4 not null
PER_FIRST_NAME nvarchar 40 not null
PER_LAST_NAME nvarchar 40 not null
PER_BIRTH_DATE DateTime 8
PER_WEIGHT_KG float 8
PER_HEIGHT_M float 8
3. 为了在开发过程更加直观，我们需要将ibatisnet日志打开以便观察ibatinets运作的细节。
ibatisnet采用IBatisNet.Common.Logging.Log4Net，就是使用Log4Net纪录日志的包装。在Web.config中增加下面的配置内容：
<configSections>
<sectionGroup name="iBATIS">
<section name="logging" type="IBatisNet.Common.Logging.ConfigurationSectionHandler, IBatisNet.Common" />
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<iBATIS>
<logging>
<logFactoryAdapter type="IBatisNet.Common.Logging.Impl.Log4NetLoggerFA, IBatisNet.Common.Logging.Log4Net">
<arg key="configType" value="inline" />
<arg key ="showLogName" value="true" />
<arg key ="showDataTime" value="true" />
<arg key ="level" value="ALL" />
<arg key ="dateTimeFormat" value="yyyy/MM/dd HH:mm:ss:SSS" />
</logFactoryAdapter>
</logging>
</iBATIS>
<!-- This section contains the log4net configuration settings -->
<log4net>
<!-- Define some output appenders -->
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="log.txt" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="2" />
<param name="MaximumFileSize" value="100KB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="Header" value="[Header]"r"n" />
<param name="Footer" value="[Footer]"r"n" />
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n" />
</layout>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] <%X{auth}> - %m%n" />
</layout>
</appender>
<!-- Set root logger level to ERROR and its appenders -->
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
<appender-ref ref="ConsoleAppender" />
</root>
<!-- Print only messages of level DEBUG or above in the packages -->
<logger name="IBatisNet.DataMapper.Configuration.Cache.CacheModel">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.DataMapper.Configuration.Statements.PreparedStatementFactory">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.DataMapper.LazyLoadList">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.DataAccess.DaoSession">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.DataMapper.SqlMapSession">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.Common.Transaction.TransactionScope">
<level value="DEBUG" />
</logger>
<logger name="IBatisNet.DataAccess.Configuration.DaoProxy">
<level value="DEBUG" />
</logger>
</log4net>
构建IBatisNet基础代码
IBatisNet 基础代码包括：
1． IBatisNet 实例配置
一个典型的配置文件如下（具体配置项目的含义见后）：
<?xml version="1.0" encoding="utf-8"?><sqlMapConfig xmlns="http://ibatis.apache.org/dataMapper" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <!-- Rem : If used via a DataAccess context, properties tag will be ignored <properties resource="http://www.cnblogs.com/database.config"/> --> <properties embedded="database.config, IBatisNetDemo"/> <settings> <setting useStatementNamespaces="${useStatementNamespaces}"/> <setting cacheModelsEnabled="true"/> <setting validateSqlMap="false"/> </settings> <!-- Optional if resource --> <providers embedded="providers.config,IBatisNetDemo"/> <!-- ==== SqlClient configuration ========= --> <!-- Rem : If used via a DataAccess context, database tag will be ignored --> <database> <!-- Optional ( default ) --> <provider name="sqlServer1.1"/> <dataSource name="iBatisNet" connectionString="data source=localhost;database=Northwind;user id=sa;password=;connection reset=false;connection lifetime=5; min pool size=1; max pool size=50"/> </database> <sqlMaps> <!-- user via embedded--> <sqlMap embedded="Map.SqlClient.Person.xml,IBatisNetDemo"/> </sqlMaps></sqlMapConfig> 2． PO（Plain Ordinary Object）
下面是我们用作示例的一个PO:
[Serializable] public class Person
{
private int id; private string firstName; private string lastName; private DateTime? birthDate; private double? weightInKilograms; private double? heightInMeters;
public Person() { 
public int Id { get { return id; } set { id = value; }
} public string FirstName { get { return firstName; } set { firstName = value; } } public string LastName { get { return lastName; } set { lastName = value; } } public DateTime? BirthDate { get { return birthDate; } set { birthDate = value; } } public double? WeightInKilograms { get { return weightInKilograms; } set { weightInKilograms = value; } } public double? HeightInMeters { get { return heightInMeters; } set { heightInMeters = value; } }} 
3．映射文件
与Hibernate 不同。因为需要人工编写SQL 代码，IBatisNet 的映射文件一般采
用手动编写（通过Copy/Paste，手工编写映射文件也并没想象中的麻烦）。
针对上面PO 的映射代码如下：
<?xml version="1.0" encoding="utf-8" ?><sqlMap namespace="Person" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > <alias> <typeAlias alias="Person" type="IBatisNetDemo.Domain.Person,IBatisNetDemo" /> </alias> <resultMaps> <resultMap id="SelectAllResult" class="Person"> <result property="Id" column="PER_ID" /> <result property="FirstName" column="PER_FIRST_NAME" /> <result property="LastName" column="PER_LAST_NAME" /> <result property="BirthDate" column="PER_BIRTH_DATE" /> <result property="WeightInKilograms" column="PER_WEIGHT_KG" /> <result property="HeightInMeters" column="PER_HEIGHT_M" /> </resultMap> </resultMaps> <statements> <select id="SelectAllPerson" resultMap="SelectAllResult"> select PER_ID, PER_FIRST_NAME, PER_LAST_NAME, PER_BIRTH_DATE, PER_WEIGHT_KG, PER_HEIGHT_M from PERSON </select> <select id="SelectByPersonId" resultClass="Person" parameterClass="int"> select PER_ID, PER_FIRST_NAME, PER_LAST_NAME, PER_BIRTH_DATE, PER_WEIGHT_KG, PER_HEIGHT_M from PERSON where PER_ID = #value# </select> <insert id="InsertPerson" parameterclass="Person" > <selectKey property="Id" type="post" resultClass="int"> ${selectKey} </selectKey> insert into Person ( PER_FIRST_NAME, PER_LAST_NAME, PER_BIRTH_DATE, PER_WEIGHT_KG, PER_HEIGHT_M) values (#FirstName#,#LastName#,#BirthDate#, #WeightInKilograms#, #HeightInMeters#) </insert> <update id="UpdatePerson" parameterclass="Person"> <![CDATA[ update Person set PER_FIRST_NAME =#FirstName#, PER_LAST_NAME =#LastName#, PER_BIRTH_DATE =#BirthDate#, PER_WEIGHT_KG=#WeightInKilograms#, PER_HEIGHT_M=#HeightInMeters# where PER_ID = #Id# ]]> </update> <delete id="DeletePerson" parameterclass="Person"> delete from Person where PER_ID = #Id# </delete> </statements></sqlMap>
从上面的映射文件可以看出，通过<insert>、<delete>、<update>、
<select>四个节点，我们分别定义了针对Person 对象的增删改查操作。在这
四个节点中，我们指定了对应的SQL 语句，以update节点为例：
……
<update id=" UpdatePerson" ⑴
parameterClass="Person"> ⑵
<![CDATA[⑶
update Person set ⑷
PER_FIRST_NAME =#FirstName#,⑸
PER_LAST_NAME =#LastName#, ⑹
PER_BIRTH_DATE =#BirthDate#,
PER_WEIGHT_KG=#WeightInKilograms#,
PER_HEIGHT_M=#HeightInMeters#
where
PER_ID = #Id# ⑺]]>
</update>
……
⑴ ID
指定了操作ID，之后我们可以在代码中通过指定操作id 来执行此节点所定
义的操作，如：
SqlMap.Update("UpdatePerson", person);
ID设定使得在一个配置文件中定义两个同名节点成为可能（两个update节
点，_____以不同id区分）
⑵ parameterClass
指定了操作所需的参数类型，此例中update 操作以
IBatisNetDemo.Domain.Person类型的对象作为参数，目标是将提供的Person
实例更新到数据库。
parameterClass="Person"中，user为“IBatisNetDemo.Domain.Person”
类的别名，别名可通过typeAlias节点指定，如示例配置文件中的：
<typeAlias alias="Person" type="IBatisNetDemo.Domain.Person,IBatisNetDemo" />⑶ <![CDATA[……]]>
通过<![CDATA[……]]>节点，可以避免SQL 中与XML 规范相冲突的字符对
XML映射文件的合法性造成影响。
⑷ 执行更新操作的SQL，这里的SQL 即实际数据库支持的SQL 语句，将由
IBatisNet填入参数后交给数据库执行。
⑸ SQL中所需的用户名参数，“# FirstName #”在运行期会由传入的Person对象的FirstName
属性填充。
⑹ SQL 中所需的用户性别参数“# LastName #”，将在运行期由传入的user 对象的
LastName属性填充。
⑺ SQL中所需的条件参数“#id#”，将在运行期由传入的Person对象的Person属性
填充。
对于这个示例，IBatisNet在运行期会读取id 为“UpdatePerson”的update节点
的SQL定义，并调用指定的user对象的对应getter方法获取属性值，并用此
属性值，对SQL中的参数进行填充后提交数据库执行。
此例对应的应用级代码如下，其中演示了IBatisNet SQLMap的基本使用方法：
private static SqlMapper sqlMap;public BaseService(){ Assembly assembly = Assembly.Load("IBatisNetDemo"); Stream stream = assembly.GetManifestResourceStream("IBatisNetDemo.sqlmap.config"); DomSqlMapBuilder builder = new DomSqlMapBuilder(); sqlMap = builder.Configure( stream ); };其中，SqlMapper是IbatisNet运作的核心，所有的操作均通过SqlMapper实例完成。这个例子中我将所有的配置文件按照资源文件方式存放，所以从程序集去加载sqlmap.config文件。
