在使用Spring MVC过程中，部署项目报错，报错信息如下：

Maven项目，application-context.xml、db.properties文件均放置在src/main/resources目录下，Tomcat部署项目，src/main/resources目录下的配置文件默认位置为：\{项目名\}/WEB-INF/classes，而Spring却在项目根目录下寻找，肯定找不到，因此，配置时指定classpath目录下寻找即可。

解决方案如下：

<context:property-placeholder location="**classpath:db.properties**" />
