Changing default json for an object in Spring Boot Application

• 
  

  I have a simple Spring Boot Application having a simple MyDateTime model class only having a java.util.Date instance variable with private access, getters/setters and default constructor.

  
  


• 
  

  A controller just instantiates this object and returns back.

  
  


• 
  

  In the output, I see that default representation of Date object is done as an Integer (maybe millis from Epoch)

  Is there any way I can change the default jsonification of Date Object into ISO-String or any other String?

  
  

EDIT:

Some Clarification:

I'm very new to Spring and Spring Boot. I'm using the template from a sample application on spring's website. JSONification is done through Jackson. Rest, I don't know much about Spring in general.
