Spring3 +mybatis3 之 MapperScannerConfigurer

之前一直使用"org.mybatis.spring.mapper.MapperFactoryBean"这个类在spring中配置mybatis的dao接口,后来发现如果dao太多话,配置非常繁冗,于是想改用

org.mybatis.spring.mapper.MapperScannerConfigurer来精简配置.

使用注意, 直接上代码吧:

1. dao的配置文件:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"

    <!-- 一定得指定这个属性!-->  default-autowire="byType"
        >

       <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
            <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"/>
       </bean>

    <!-- 无需指定其他属性 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- value是dao接口类所处的package-->
        <property name="basePackage" value="com.jd.jd_ptesting.dao" />
    </bean>
</beans>

2.  Service 配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"
default-autowire="byType"
>

<bean id="settingService" class="com.jd.jd_ptesting.service.impl.SettingServiceImpl">
       <!-- 注意 此处一定不要指定dao属性!!!
        <property name="settingDao" ref="settingDao" />
        -->
    </bean>
 
</beans>
