I've been looking for Notfound annotation. I have handled like, ObjectNotFoundException in my catch block. This is cool. I'm gonna try this today. Thank you for your effort.

@NotFound(action = NotFoundAction.IGNORE) is not working with me??

[harshadkalantri]

Got this error - object references an unsaved transient instance - save the transient instance before flushing. Can you tell me how to resolve ?

Dear Koushik,
will you please answer my two questions?

1. Do we need to remove @ManyToOne to Cascade to work?
2. did I understand correct that if Vehicle is a ValueObject then saving its instances to collection on One-side saves them as well (no cascading needed in that case)?

Thank you

Hi Koushik, Awesome explanation. I have one query. Why don't you using a mapping file?? Which one is preferred? plz let me know. Thank you

[LeBadman]

Why would a CRUD operation on UserDetails affect all the Vehicles?.. I don't understand this. Does someone know, please?

[andrei-unyr]

I'm not getting an exception when using @NotFound(action = NotFoundAction.EXCEPTION) or by not setting it at all.
I instead get null. Does anyone know why?

Hi Koushik, Thanks for this tutorial. I don't get an exception even if I don't use @NotFound. what am I missing?

[maxfeldman]

Any one knows if this series of tutorial's still relevant for 2021?

[Betrayed]

do note this only works if you

import

If you use

import org.hibernate.CascadeType

It will probably not work. I had this issue.
