sir, when we created User entity we annotated the fields with @Column(nullable=false)...why is hibernate letting null values be inserted in database...why do we need to validate again the Dto objects?

[@mahimatolani813]

Because UserDto is interacting with our user not the User Entity is directly in interaction

[@pankajverma2393]

Hi Durgesh, I'm consuming an external API response in my spring boot application. Should i use bean validation for the Response DTO that will map the json response? Is it a good programming practice ?

[@Md.Naser-Bin-Hossain]

Thank You sir for your valuable lectures and guidelines . By following the guidelines I am able to know the spring boot api concepts. Unfortunately, I am facing a problem in database when ever I change any portion in my code the Id of the database value changed by default 50 gave not in sequential like-1,2,3. Even I deleted the id sequence is still same as before. How can I generated the id sequential even the id is deleted. If you know me that will be very efficient for me.

[@BGMICLASHES]

Truncate the table after u are done with all. The changes in the code and then go on inserting the data the id will be in sequential manner

[@akshayengineer2018]

Awesome ...

[@Vithal_Nivargi]

Thank-you, I would request pls add in next video -if we have alredy data exist in DB after that, still if we want to insert same data it in db, it should not create another id . our require is duplicate date should be update only, instead of creating new row....
