Mybatis学习（四）——Mybatis和Spring整合中applicationContext说明

Mybatis与Spring整合推翻前面的配置，使用applicationContext配置SqlMapperConfig.xml里参数

1. 使用SqlSessionFactoryBean对象配置 

　　DataSource（数据源），configLocation（sqlMapperConfig.xml地址），mapperLocations（xxxMapper.xml地址），typeAlisesBase（domain内mapper的类名别名）

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

 

2. 使用MapperScannerConfigurer配置

　　basePackage（mapper包里mapper接口，会自动实例化mapper对象。直接@Autowrited即可）

    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="xyz.javaswing.mapper"/>
    </bean>

 

使用

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

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8"/>
        <property name="user" value="root"/>
        <property name="password" value="844597608a"/>
    </bean>

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

    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="xyz.javaswing.mapper"/>
    </bean>

    <bean id="roleService" class="xyz.javaswing.service.impl.RoleServiceImpl">

    </bean>

</beans>
