Spring.Net占位符异常

标签： .net-4.0 .net-3.5 spring.net

在尝试将我的项目从.NET 3.5转换为.NET 4时，我遇到了Spring.net最棘手的问题。

让我总结一下我们的架构： 项目A（不在我的控制下）有一个Sprint.Net配置引用一个设置（configurationProvider.url），如下所示：

<constructor-arg name="Url" value="${configurationProvider.url}" />

项目B（我的项目，在我的控制下）有另一个配置文件，其中包含此设置的值：

<configuration>
  <Environment>
    <add key="Dashboard.Environment"      value="UAT" />
    <add key="configurationProvider.url"  value="http://something/ConfigurationProvider.asmx"/>
    <add key="pkicheck.url"               value="http://something/webservices/pkicheck.asmx"/>
    <add key="sso.url"                    value="http://something/webservices/ssoclient.asmx"/>
  </Environment>
</configuration>

当Project B是.NET 3.5时，一切正常。 将此项目转换为.NET 4（这是唯一的更改）时，整个事情开始失败，并且它给了我这个例外：

Could not resolve placeholder 'configurationProvider.url'

显然没有在ProjectB配置文件中找到配置设置，尽管此文件存在且包含值。 什么可以在3.5和4之间改变？

完全例外：

答案 0 :(得分：1)

我最终发现了这个问题。 我们在配置中使用PropertyPlaceholderConfigurer，我们从不设置“Order”属性。因此Spring在Order上“排序”，但由于Order总是等于int.Max，因此订单输出是非确定性的。

将Order添加到配置文件中修复它。
