控制类

@Controller

public class TeacherOrderController {
 @Autowired
 TeacherOrderService teacherOrderService;
 @Autowired
 HttpServletRequest request;
 @ResponseBody
 @RequestMapping(value = "orders")
 public Map<String, Object> getAllOrders(int page, int limit) throws IOException {
  List<Teacher_Order> orders = teacherOrderService.getAllOrders();
  List<Teacher_Order> order = teacherOrderService.getAllOrderCount(page, limit);
  Map<String, Object> tableData = new HashMap<String, Object>();
  tableData.put("code", 0);
  tableData.put("msg", "");
  tableData.put("count", orders.size());
  tableData.put("data", order);
  System.out.println("tableData:" + tableData);
  return tableData;
 }

业务类

@Service
public class TeacherOrderService {
 @Autowired
 TeacherOrderDao teacherOrderDao;
 public List<Teacher_Order> getAllOrders() {
  return teacherOrderDao.getAllOrders();
 }
 public List<Teacher_Order> getAllOrderCount(int page, int pageSize) {
  return teacherOrderDao.getAllOrderCount(page, pageSize);
 }

Dao

@Component
public interface TeacherOrderDao {
 public List<Teacher_Order> getAllOrders();
 public List<Teacher_Order> getAllOrderCount(int page,int pageSize);
 }

DaoImpl

@Repository
public class TeacherOrderDaoImpl implements TeacherOrderDao { 
 @Autowired
 JdbcTemplate jdbcTemplate;
 @Override
 public List<Teacher_Order> getAllOrders() {   
  String sql = "select * from teacher_order";
  RowMapper<Teacher_Order> rowMapper = new BeanPropertyRowMapper<Teacher_Order>(Teacher_Order.class);
  List<Teacher_Order> orders = jdbcTemplate.query(sql, rowMapper);
  System.out.println("所有信息:" + orders);
  return orders;
 } 
  @Override
 public List<Teacher_Order> getAllOrderCount(int page, int pageSize) {
  int start = (page - 1) * pageSize;
  String sql = "select * from teacher_order limit " + start + " ,?";  
  RowMapper<Teacher_Order> rowMapper = new BeanPropertyRowMapper<Teacher_Order>(Teacher_Order.class);
  List<Teacher_Order> orders = jdbcTemplate.query(sql, rowMapper, pageSize);
  return orders;
 }
