③建立相應的包、目錄
對應：
<!-- 指定 Mapper 配置檔案的位置 -->
<property name="mapperLocations" value="classpath:mapper/*Mapper.xml"/>
<!-- 掃描 Mapper 介面 -->
<mybatis:scan base-package="com.atguigu.imperial.court.mapper"/>
<!-- 配置對 Service 所在包的自動掃描 -->
<context:component-scan base-package="com.atguigu.imperial.court.service"/>
<!-- 配置自動掃描的包 -->
<context:component-scan base-package="com.atguigu.imperial.court.controller"/>
<property name="prefix" value="/WEB-INF/templates/"/>
