為什么報錯
為什么我的<context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true"/>報錯，說是無法找到context:property-placeholder的聲明；
表頭我加了
?xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/context/spring-context.xsd
配置，在網上找說是沒加剛才的配置
