Hi Shahza,

You need to add a @GeneratedValue annotation for @Id column, otherwise the default GenerationType.ASSIGNED is used which requires the value to be set manually.

Please check Hibernate documentation for the proper GenerationType in case of generated column is used as an id, I'm not sure that would work without a special generator.

Additionally, if you're planning to use this table as a MySQL Document Store collection, please note that it doesn't conform the required structure. X Plugin requires the special "_id" name both for id column and in JSON document.

Thanks,
Alex
