@Override
    public PageResult findPage(TbBrand brand, int pageNum, int pageSize) {
        
        PageHelper.startPage(pageNum, pageSize);//分页    
        
        TbBrandExample example=new TbBrandExample();
        
        Criteria criteria = example.createCriteria();
        if(brand!=null){
            if(brand.getName()!=null && brand.getName().length()>0){
                criteria.andNameLike("%"+brand.getName()+"%");
            }
            if(brand.getFirstChar()!=null && brand.getFirstChar().length()>0){
                criteria.andFirstCharLike("%"+brand.getFirstChar()+"%");
            }            
        }
        
        Page<TbBrand> page = (Page<TbBrand>) brandMapper.selectByExample(example);
        
        return new PageResult(page.getTotal(), page.getResult());
    }
