Caused by: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 12 in XML document from class path resource [spring/spring-dao.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 12; columnNumber: 76; cvc-datatype-valid.1.2.1: ‘classpath:jdbc.properties’ 不是 ‘boolean’ 的有效值。

说的是xml配置有问题，而且行号和列号都给得很明确呢，

‘classpath:jdbc.properties’ 不是 ‘boolean’ 的有效值。

希望同学能提升一下独立解决问题的能力，提前工作中将要独立解决问题的事情多做准备

以下是我得jdbc.properties读取的配置，可以参考一下
