classpath	优先本项目class路径查找，没有的话依次在其他jar包中class路径查找，找到第一个匹配的为止

classpath*	加载到所有class路径下的配置文件，包括jar包的class路径下，最终加载所有匹配的

file	        通过URL加载，来源为文件系统（注意文件读取权限）

http	        通过URL加载，来源为网络

(none)	        根据 ApplicationContext 进行判断（这个我没试过）

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

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