tkMapper的使用

4.1 创建数据表

4.2 创建实体类

4.3 创建DAO接口

tkMapper已经完成了对单表的通用操作的封装，封装在Mapper接口和MySqlMapper接口；因此如果我们要完成对单表的操作，只需自定义DAO接口继承Mapper接口和MySqlMapper接口

public interface UserDAO extends Mapper<User>, MySqlMapper<User> {
}

4.4 测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = TkmapperDemoApplication.class)
public class UserDAOTest {

@Autowired
private UserDAO userDAO;

@Test
public void test(){
User user = new User();
user.setUsername("aaaa");
user.setPassword("1111");
user.setUserImg("img/default.png");
user.setUserRegtime(new Date());
user.setUserModtime(new Date());
int i = userDAO.insert(user);
System.out.println(i);
}

}
