Spring3 +mybatis3 之 MapperScannerConfigurer

標籤：style   blog   http   io   ar   color   使用   sp   檔案   

    之前一直使用"org.mybatis.spring.mapper.MapperFactoryBean"這個類在spring中配置mybatis的dao介面,後來發現如果dao太多話,配置非常繁冗,於是想改用

org.mybatis.spring.mapper.MapperScannerConfigurer來精簡配置.

  使用注意, 直接上代碼吧:

  1. dao的設定檔:      

<?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"

 <!-- 一定得指定這個屬性!--> 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>

    <!-- 無需指定其他屬性 -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- value是dao介面類所處的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 此處一定不要指定dao屬性!!!        <property name="settingDao" ref="settingDao" />        -->    </bean></beans>
