iBatisNet入门示例源码详解

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：

NameTypeSize

PER_IDLongInteger4 not null

PER_FIRST_NAMEnvarchar40 not null

PER_LAST_NAMEnvarchar40 not null

PER_BIRTH_DATE DateTime8

PER_WEIGHT_KGfloat8

PER_HEIGHT_Mfloat8

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] &lt;%X{auth}&gt; - %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="../../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; }

}
