先编写sql脚本，查询好需要导入redis的数据，同时在脚本中设定好redis的类型；最外层的查询需要设定好查询的字段数量，key value各算一个。

我用的是hash结构，将表明以key的形式存储，字段+对应的值以json格式存储，脚本在图片下方

脚本上传到服务器后使用此命令导入数据(用户名密码、脚本路径自行更改)：mysql -uroot -p123456 -h 127.0.0.1 database--skip-column-names --raw

SELECT CONCAT(

"*4\r\n",

'$', LENGTH(redis_cmd), '\r\n',

redis_cmd, '\r\n',

'$', LENGTH(redis_key), '\r\n',

redis_key, '\r\n',

'$',LENGTH(hkey),'\r\n',hkey,'\r\n',

'$',LENGTH(hval),'\r\n',hval,'\r\n'

)

FROM(

SELECT

'HSET' AS redis_cmd,

'tab_product' AS redis_key,

a.product_id AS hkey,

CONCAT(

'{"id":"', a.id,'"',

',"productId":"', a.product_id,'"',

',"shopId":"', a.shop_id,'"',

',"title":"', a.title,'"',

',"address":"', ifnull(e.address,''),'"',

',"businessHours":"', ifnull(e.business_hours,''),'"',

',"pension":"', round(ifnull(e.pension_scale,0) * a.price, 2),'"',

',"productImageList":', ifnull(CONCAT('[',GROUP_CONCAT('{"img":"',b.img, '"}'),']'),''),'}'

) AS hval

FROM `tab_product` a

LEFT JOIN tab_product_image b on a.product_id = b.product_id and b.state = 0

LEFT JOIN tab_product_tag c on c.product_id = a.product_id and c.state = 0

LEFT JOIN tab_tag d on d.id = c.tag_id and d.state = 0

LEFT JOIN shop.tab_shop e on e.shop_id = a.shop_id

group by a.id

) AS t

这是HSET结构，用到的改一下上面的就可以了
