Mybatis中接口和对应的mapper文件位置配置深入剖析

Maven Spring mapper文件路径配置方法

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:mybatis="http://mybatis.org/schema/mybatis-spring"
  xsi:schemaLocation="
  http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd">
  <!-- 配置接口存储的包，用来扫描mapper接口 -->
  <mybatis:scan base-package="edu.zju.bme.data.manage.mapper" />
  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <!-- 配置mapper文件位置，扫描映射文件，可以使用Ant风格的路径格式 -->
    <property name="mapperLocations" value="classpath*:mappers/mapper/*.xml" />
    <!-- 指定mybaits与spring结合的配置文件 -->
    <property name="configLocation" value="classpath:mybatis/sqlMapcfg.xml" />
    // ...
  </bean>
</beans>

至于接口的话，则是如下配置

<!-- 指定dao接口地址即注入seqSessionFactory -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.qufenqi.pay.channel.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
