MyBatis-Plus单表分页

1. orderNO（排序用的）：是前台传过来的，根据orderNO（类似下标）找到前台定义好的数据库字段
2. order（排序用的）：根据orderNO（类似下标）找到前台定义好的数据库字段
3. orderdir（排序用的：是asc   还是desc）
4. 前台还传了userName  模糊查询

/**
	 * 前台传递的URL：/users/usersPage
	 * 
	 * @param param
	 * @param request
	 * @return
	 */
	@ResponseBody
	@GetMapping(value = "/usersPage")
	public ResponseData usersPage(SearchParam param,String userName, HttpServletRequest request) {
		logger.info("usersPage ...........");
		String orderNO = request.getParameter("order[0][column]");
		String order = request.getParameter("columns[" + orderNO + "][name]");
		String orderdir = request.getParameter("order[0][dir]");
		
		EntityWrapper<User> ew = new EntityWrapper<>();
		ew.like("user_name", userName).orderBy(order, "asc".equals(orderdir) ? true : false);

		Page<User> pageDate = userService.selectPage(new Page<User>(param.getStart(), param.getLength()), ew);

		return responseData(param.getDraw(), pageDate);

省去get set方法
