Apache Commons Configuration 2.1 发布了，Apache Commons Configuration 是 Apache 提供的一个组件，用于读取保存有配置参数的 XML 文件。该版本是 Apache Commons Configuration 2.x 的首个维护版，修复了一些 bug，也提供了一些新功能，例如对于 Spring 框架更好的整合。 该版本更新如下： New Features CONFIGURATION-636 PropertiesConfigurationLayout now allows manipulating the order of keys when the properties file is written. CONFIGURATION-624 Support Commons Configuration as PropertySource in Spring. Fixed Bugs CONFIGURATION-634 HomeDirectoryLocationStrategy now works correctly in the mode that evaluates the FileLocator's base path. CONFIGURATION-633 Interpolation was improved to better support properties with multiple values. CONFIGURATION-632 The methods getStringArray() and getList() of CompositeConfiguration now support the interpolation of variables that reference properties with multiple values.
