Spring 5.0 注解配置bean 04

Spring 配置文件

base-package属性指定一个需要扫描的基类包，Spring容器将会扫描这个基类包里及其子包中的所有类
　　　　当需要扫描多个包时，可以使用逗号分隔
　　　　如果仅希望扫描特定的类而非基包下的所有类，可使用resource-pattern属性过滤特定的类，示例：
　　　　<context:component-sacn base-package="com.yl.spring.beans" resource-pattern="autowire/*.class"/>
　　　　<context:include-filter>子节点表示要包含的目标类
　　　　<context:exclude-filter>子节点表示要排除在外的目标类
　　　　<context:component-sacn>下可以拥有若干个<context:include-filter>和<context:exclude-filter>子节点
