使用spring.net+nibernate时如何用aspnet_regiis加密数据库连接字符串

使用spring.net+nibernate时数据库连接往往是放在一个 <db:provider ...  />字段中的

不能使用aspnet_regiis直接加密

解决办法是引入一个专门负责键值对应的配置节

<section name="databaseSettings" type="System.Configuration.NameValueSectionHandler" />

在这个配置节中声明重要的连接参数

<databaseSettings>
     <add key="db.datasource" value=".\SQLEXPRESS; Integrated Security=true; AttachDbFilename=|DataDirectory|northwnd.mdf; User Instance=true;"/>
     <add key="db.user" value="springqa"/>
     <add key="db.password" value="springqa"/>
     <add key="db.database" value="Northwind"/>
</databaseSettings>

在 Spring.NET 中，通过 PropertyPlaceholderConfigurer 读取配置参数，以便在 Spring.NET 中使用

<!-- Property placeholder configurer for database settings -->
 <object type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core">
    <property name="ConfigSections" value="databaseSettings"/>
</object>

最后,把 <db:provider ...  />字段中的内容改换成 以通配符的形式声明

<db:provider id="SqlServerDbProvider" provider="System.Data.SqlClient" connectionstring="Data Source=${db.datasource};database=${db.database};uid=${db.user};pwd=${db.password};">
</db:provider>

这样加密的时候只要加密

<databaseSettings>
     <add key="db.datasource" value=".\SQLEXPRESS; Integrated Security=true; AttachDbFilename=|DataDirectory|northwnd.mdf; User Instance=true;"/>
     <add key="db.user" value="springqa"/>
     <add key="db.password" value="springqa"/>
     <add key="db.database" value="Northwind"/>
</databaseSettings>

这段就行了,加密后的效果

<databaseSettings configProtectionProvider="RsaProtectedConfigurationProvider">
