My h2 database not showing any post table..while first running server...stuck as to how to solve it

[@wazoowebbytes]

do you see any error in the logs while starting up the server?

[@anishkr7888]

@@wazoowebbytes no there are no errors . It's starting perfectly.

[@wazoowebbytes]

@@anishkr7888 I can't recreate that. I see it every time in /h2-console. Have you tried shutting the server down, deleting the "data" folder, then starting it up again? (You probably already have, I'm just making sure)

[@anishkr7888]

@@wazoowebbytes it's giving error - 0 jpa interfaces found....even though I followed each line of code as u said...where m I getting wrong..please help

[@wazoowebbytes]

@@anishkr7888 the only other thing I can think of is that your repository object is somehow not declared or found correctly by spring boot. Is there a space at all in your project path?

[@petmik5022]

why use ReqArgsConstrucotr anotation? doesnt make sense, you have no final fields in classes to compile contructor

[@wazoowebbytes]

Thanks for pointing that out - yeah in one of the versions of my codebase, I DID have a final field in that class, so it must've been a leftover from that work. Appreciate it!
