<!--本示例采用DBCP连接池，应预先把DBCP的jar包复制到工程的lib目录下。
连接池配置如下-->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost/courseman"/>
<property name="username" value="courseman"/>
<property name="password" value="abc123"/>
</bean>
<bean id="sqlSessionFactory"
class="org.mybatis.spring.SqlSessionFactoryBean">
<!--dataSource属性指定要用到的连接池-->
<property name="dataSource" ref="dataSource"/>
<!--configLocation属性指定mybatis的核心配置文件-->
<property name="configLocation" value="resources/configuration.xml"/>
</bean>
<bean id="studentMapper"
class="org.mybatis.spring.mapper.MapperFactoryBean">
<!--sqlSessionFactory属性指定要用到的SqlSessionFactory实例-->
<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
<!--mapperInterface属性指定映射器接口，用于实现此接口并生成映射器对象-->
<property name="mapperInterface"
value="com.abc.mapper.StudentMapper"/>
</bean>
<bean id="teacherMapper"
class="org.mybatis.spring.mapper.MapperFactoryBean">
<!--sqlSessionFactory属性指定要用到的SqlSessionFactory实例-->
<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
<!--mapperInterface属性指定映射器接口，用于实现此接口并生成映射器对象-->
<property name="mapperInterface"
value="com.abc.mapper.TeacherMapper"/>
</bean>
<!--解决以上多个mapper配置繁琐问题 -->
<!--MapperScannerConfigurer配置-->
<!--
1.无需指定引用SqlSessionFactory，因为MapperScannerConfigurer在创建映射器时会通过自动装配的方式来引用。
2.映射器接口TeacherMapper被扫描后创建的映射器bean名为teacherMapper
TeacherMapper mapper = (TeacherMapper)ctx.getBean("teacherMapper");
3.可以指定名称：@Component
@Component("myTeacherMapper")
public interface TeacherMapper {}
TeacherMapper mapper = (TeacherMapper)ctx.getBean("myTeacherMapper");
4.若映射器接口（如TeacherMapper接口）与相应的映射配置文件（TeacherMapper.xml）同名且在同一目录下，就无需在核心配置文件configuration.xml中使用mappers元素来指定映射配置文件了

<!--
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--basePackage指定要扫描的包，在此包之下的映射器都会被
搜索到。可指定多个包，包与包之间用逗号或分号分隔-->
<property name="basePackage" value="com.abc.mapper"/>
</bean>
-->
