步骤：
1）、配置数据源相关属性（见上一节Druid）
2）、给数据库建表
3）、创建JavaBean
注解版
//指定这是一个操作数据库的mapper @Mapper public interface DepartmentMapper { @Select("select * from department where id=#{id}") public Department getDeptById(Integer id); @Delete("delete from department where id=#{id}") public int deleteDeptById(Integer id); @Options(useGeneratedKeys = true, keyProperty = "id") @Insert("insert into department(departmentName) values(#{departmentName})") public int insertDept(Department department); @Update("update department set departmentName=#{departmentName} where id=#{id}") public int updateDept(Department department); }
问题：
自定义MyBatis的配置规则；给容器中添加一个ConfigurationCustomizer；
@org.springframework.context.annotation.Configuration public class MyBatisConfig { @Bean public ConfigurationCustomizer configurationCustomizer() { return new ConfigurationCustomizer() { @Override public void customize(Configuration configuration) { configuration.setMapUnderscoreToCamelCase(true); } }; } }
使用MapperScan批量扫描所有的Mapper接口；
@MapperScan(value = "com.atguigu.springboot.mapper") @SpringBootApplication public class SpringBoot06DataMybatisApplication { public static void main(String[] args) { SpringApplication.run(SpringBoot06DataMybatisApplication.class, args); } }
配置文件版
mybatis: config‐location: classpath:mybatis/mybatis‐config.xml 指定全局配置文件的位置 mapper‐locations: classpath:mybatis/mapper/*.xml 指定sql映射文件的位置
