本文介绍了一个关于Spring框架中dataSource配置出现BeanDefinitionStoreException的问题及其解决方案。问题源于applicationContext.xml文件中的dataSource定义中使用了无法解析的占位符${jdbc.driverClassName}

org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'dataSource' defined in file [D:\Workspaces\MyEclipse 10\SpringJdbc2\bin\applicationContext.xml]: Could not resolve placeholder 'jdbc.driverClassName' in string value "${jdbc.driverClassName}"

这个错误很简单就是你的jdbc.properties里的name名称出现错误了，和applicationContext的引用不一致

除去properites文件路径错误、拼写错误外，出现"Could not resolve placeholder"很有可能是使用了多个PropertyPlaceholderConfigurer或者多个的原因。  一定要记住，不管是在一个Spring文件还是在多个Spring文件被统一load的情况下，直接写 是不允许的。
