当我查看 Spring Boot 时，我喜欢它的想法：

如果您想更改默认设置，请快速避开。- Dave Syer，2013 年春季一号 2GX

没过多久，实用性就击中了我。在尝试使 Boot 与 100% Groovy/no-XML 宠物项目一起工作时，我在 2 天内发现了 2 个问题。这是其中之一。

Groovy 配置文件：

beans {
  xmlns([ctx:'http://www.springframework.org/schema/context'])
  ctx.'component-scan'('base-package':'name.abhijitsarkar.moviedatabase')
}

例外：

Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read XML document; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Unable to determine validation mode for [Groovy]: cannot open InputStream. Did you attempt to load directly from a SAX InputSource without specifying the validationMode on your XmlBeanDefinitionReader instance?; nested exception is java.io.FileNotFoundException: Groovy cannot be opened because it does not point to a readable resource
