@Service
public class StuServiceImpl implements StuService 


    @Autowired
    private Stu_infoMapper stu_infoMapper;


    @Override
    public PageInfo<Stu_info> getAllStu(int currentPage, int pageSize) 

        PageHelper.startPage(currentPage,pageSize);

        List<Stu_info> stuInfoList =stu_infoMapper.AllStu();

        PageInfo pageInfo = new PageInfo(stuInfoList);

        return pageInfo;
    

5.dao和mapper

public List<Stu_info> AllStu();

　　

 <select id="AllStu" resultMap="BaseResultMap">

           select  * from  stu_info ORDER BY id

  </select>
