iBATIS.NET 学习笔记(二)

在VS.NET2003中使用iBATIS.NET，添加 SqlMap.xsd, SqlMapConfig.xsd, providers.xsd三个文件到C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Packages\schemas\xml
这样在编辑iBATIS.NET配置文件时，有提醒出现，更易用。如下所示：

SqlMap.Config 配置文件示例，(此文件放在web.config同目录)

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

   <!--  Optional  -->
   < properties  resource ="properties.config" />

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

   <!--  Not required if providers.config is located in default location  -->
   < providers  embedded ="resources.providers.config, IBatisNet.Test" />

   < database >
     < provider  name ="sqlServer1.1" />
     < dataSource  name ="NPetshop"  
                connectionString ="user id=${username};
                password=${password};
                data source=${datasource};
                database=${database};" />
   </ database >

   < alias >
     < typeAlias  alias ="Account"  type ="IBatisNet.Test.Domain.Account, IBatisNet.Test" />
     < typeAlias  alias ="YesNoBool"
         type ="IBatisNet.Test.Domain.YesNoBoolTypeHandlerCallback, IBatisNet.Test" />
   </ alias >

   < typeHandlers >
     < typeHandler  type ="bool"  dbType ="Varchar"  callback ="YesNoBool" />
   </ typeHandlers >

   < sqlMaps >
     < sqlMap  resource ="${root}Maps/Account.xml" />
     < sqlMap  resource ="${root}Maps/Category.xml" />
     < sqlMap  resource ="${root}Maps/Product.xml" />
   </ sqlMaps >  
</ sqlMapConfig >
