1：添加依赖

compile group: 'com.github.pagehelper', name: 'pagehelper-spring-boot-starter', version: '1.2.9' 注意：在spring-boot中一定要使用 pagehelper-spring-boot-starter而不是pagehelper，否则分页不起作用。

2：应用案例

@RequestMapping(            value = "/page",            method = RequestMethod.GET    )    public ResultVo getUserPages(@RequestParam Integer pageNum, @RequestParam Integer pageSize){        PageHelper.startPage(pageNum, pageSize);//一定要在userMapper.getUsers()之前执行        List
     
       list = userMapper.getUsers();        PageInfo
      
        pageInfo = new PageInfo<>(list,pageSize);        return ResultUtil.dealPageResult(pageInfo, "用户分页信息");    }
