12、映射语句文件Student类的sql语句文件StudentMapper.xmlresultMap标签：表字段与属性的映射。Select标签：查询sql。Xml代码 1. 2. !DOCTYPEmapperPUBLIC-/mybatis.org/DTDMapper3.0/EN/mybatis.org/dtd/mybatis-3-mapper.dtd3. namespace=com.manager.data.StudentMapperresultstudentNameSTUDENT_NAMEstudentSexSTUDENT_SEXstudentBirthdaySTUDENT_BIRTHDAY/r

14、= id= select id= parameterType= resultType= resultMap=CDATA SELECT * from STUDENT_TBL ST WHERE ST.STUDENT_ID = #studentID - 查询学生列表 - SELECT * from STUDENT_TBL1.2.3.4创建MyBatis的mapper配置文件在src/main/resource中创建MyBatis配置文件：mybatis-config.xml。typeAliases标签：给类起一个别名。com.manager.data.model.StudentEntity类，可以使

15、用StudentEntity代替。Mappers标签：加载MyBatis中实体类的SQL映射语句文件。configurationConfig/mybatis.org/dtd/mybatis-3-config.dtdconfigurationtypeAliasestypeAliasalias=/typeAliasesmappersresource=com/manager/data/maps/StudentMapper.xml/mappers10.

16、= type=mapper resource= /1.2.3.5修改Spring 的配置文件主要是添加SqlSession的制作工厂类的bean：SqlSessionFactoryBean，（在mybatis.spring包中）。需要指定配置文件位置和dataSource。和数据访问接口对应的实现bean。通过MapperFactoryBean创建出来。需要执行接口类全称和SqlSession工厂bean的引用。导入属性配置文件context:property-placeholderlocation=classpath:mysql.properties4. beandataSourceclass=org.springframework.jdbc.datasource.DriverManagerDataSourceproperty
