1.定义节点
下面两个都定义为键值对
<section name="DaoConfiguration" type="System.Configuration.NameValueSectionHandler"/>
<section name="DatabaseConfiguration" type="System.Configuration.NameValueSectionHandler"/><DaoConfiguration>
The IoC container
Spring Framework (Version 1.3.2) 68<add key="maxResults" value="1000"/></DaoConfiguration><DatabaseConfiguration><add key="connection.string" value="dsn=MyDSN;uid=sa;pwd=myPassword;"/></DatabaseConfiguration>2.应用替换
<objects xmlns="http://www.springframework.net"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.nethttp://www.springframework.net/xsd/spring-objects.xsd" ><object name="productDao" type="DaoApp.SimpleProductDao, DaoApp "><property name="maxResults" value="${maxResults}"/><property name="dbConnection" ref="myConnection"/></object><object name="myConnection" type="System.Data.Odbc.OdbcConnection, System.Data"><property name="connectionstring" value="${connection.string}"/></object>
<!--用于spring容器的注时替换，后处理器--><object name="appConfigPropertyHolder"type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core"><property name="configSections"><value>DaoConfiguration,DatabaseConfiguration</value></property></object>
</objects>第二种方法，spring环境变量模式
<object name="appConfigPropertyHolder"type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core"><property name="configSections" value="DaoConfiguration,DatabaseConfiguration"/><property name="EnvironmentVariableMode" value="Override"/></object>
</objects>
<configuration>
The IoC container
Spring Framework (Version 1.3.2) 70<configSections><sectionGroup name="spring"><section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/></sectionGroup><section name="DaoConfigurationOverride" type="System.Configuration.NameValueSectionHandler"/></configSections><DaoConfigurationOverride><add key="productDao.maxResults" value="1000"/></DaoConfigurationOverride><spring><context><resource uri="assembly://DaoApp/DaoApp/objects.xml"/></context></spring>
</configuration>
之后也只差应用了
<objects xmlns="http://www.springframework.net"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.net http://www.springframework.net/xsd/springobjects.xsd"
><object name="productDao" type="PropPlayApp.SimpleProductDao, PropPlayApp " ><property name="maxResults" value="2000"/><property name="dbConnection" ref="myConnection"/><property name="log" ref="daoLog"/></object><object name="daoLog" type="Spring.Objects.Factory.Config.LogFactoryObject, Spring.Core"><property name="logName" value="DAOLogger"/></object><object name="myConnection" type="System.Data.Odbc.OdbcConnection, System.Data"><property name="connectionstring"><value>dsn=MyDSN;uid=sa;pwd=myPassword;</value></property></object><object name="appConfigPropertyOverride" type="Spring.Objects.Factory.Config.PropertyOverrideConfigurer,Spring.Core"><property name="configSections"><value>DaoConfigurationOverride</value></property></object>
</objects>
