Meh Sar :
I'm beginner in JPA and I'm just trying to fetch some data from my DB via hibernate but I failed and I got this error :

I reviewed another question that were similar to my title but It doesn't help. can anyone plz help me to solve this issue ?
UPDATE
These are my rows with publish_time columns:
peekay :
This is likely a data issue (in the database table).
A mysql table could contain datetime / timestamp entries like 2019-00-00. While such dates are valid in mysql (depending on the server version and mode), they will cause an exception when the mysql driver tries to parse them into Java dates.
Double check that the rows you are trying to retrieve have valid dates in the publish_time column.
ps. if you have all zero dates (0000-00-00 00:00:00) then you can use the zeroDateTimeBehavior property in the connection string to handle them more gracefully without changing the database values.
