I encountered an error today. Running rankdao. Selectbyid (ID) directly reported an error to me. I didn’t understand it

Error message:

At the beginning, Baidu has various methods, some say

an error is reported when the value of the column in the created table is less than the actual value. The @ resource or @ Autowired annotation is forgotten on the service interface introduced by the controller layer. The method called by the controller layer is private, resulting in distribution failure. Check whether the mapper interface code conforms to the specification (automatically ignored by mybatis plus)

I tried again, but I still couldn’t, so I took the wrong SQL statement and executed it

SELECT id,song_list_id,consumer_id,score FROM rank WHERE id=1

Still report an error

music> SELECT id,song_list_id,consumer_id,score FROM rank WHERE id=1
[2021-09-22 10:55:58] [42000][1064] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rank WHERE id=1' at line 1

Then I was confused. Then I removed the query statement and still reported an error

SELECT id,song_list_id,consumer_id,score FROM rank

Then Baidu saw that because rank is a keyword, it can not be directly used as a non keyword. It needs to be used with `. It can be executed after replacement

SELECT id,song_list_id,consumer_id,score FROM `rank`

Then I modified the table name and solved the error!!!
