Just one question that if I am passing the hobbies json name as "HOBBIES" and rest the same I am getting the exception of unrecognized filed, not marked as ignorable and while checking it I found that internally hibernate is changing the name of the HOBBIES to hobbies even if I am trying to create the name as private HOBBIES HOBBIES; and this is the reason why I m getting that error and if I am keeping passing my json object as hobbies:{} then it working fine but HOBBIES :{} is not working

how to use JPA repository to fetch such object ... I am getting exception as -> cannot deserialize instance of java.lang.string out of start_object token

What of the case when the data is coming from the client ? How do you use @ResponseBody for nested Json data .

[viratsuresh]

Json string to java object conversion. But my java object has map in it along with other variables.


Map<String, Employee>


In that case how we can achieve it.

Great video, but please answer my question. I use mongodb with sprinboot. I never use obejectmapper their. I create my class as per JSON fields. Somehow, JSON is directly mapped to object. I don't know how this happen or this happen with mongodb only.
Please share you thought and share some link to read more about it.

Cheers !!
