The status property holds the operation call status. "subErrors": [ Spring supports exception handling by a global Exception Handler (@ExceptionHandler) with Controller Advice (@ControllerAdvice). I've updated the sample code (https://github.com/brunocleite/spring-boot-exception-handling) with an example. @ExceptionHandler(Exception.class) This way we can in just one place define how to treat such an exception and this handler will be called when the exception is thrown from classes that are covered by this ControllerAdvice.

Hello Nico! Spring MVC Framework provides following ways to help us achieving robust exception handling. How can I achieve that?
