@Valid不适用于jax rs和springboot

Question

I am getting NotFoundException while trying to implement custom exception handling in spring-boot rest application.

The code was working fine when I was using MVC (using @ControllerAdvice ) annotations but not sure when I am sending a data which is violating the constraint mentioned in entity(pojo class) it is throwing only NotFoundException (for all validation failure) but not the MethodViolationException or ConstraintViolationException

I am not able to send the message for that particular violation.

Not sure where I am making this mistake. Please help

Code:

@POST
@Path("/customers/add") 
public Response addCustomer(@Valid customer cust) 
{

// Rest of the code

} 

POJO:

@Entity
@Table(name="cust")
public class Customer
{
  @NotNull
  @Size(min=1,max=50,message ="invalid name") 
  String name;

}

Exception Handler:

@Provider
public class CustomHandler implements ExceptionMapper<Exception>
{
 public Response toResponse(Exception ex) 
 {
  if(ex instanceOf ConstraintViolationException) 
  {
    Do something
  } 
} 

**UPDATE 1

If I enable the send_error_in_response i am getting the message for this but not sure why my custom exception handler is not able to catch this exception and only throwing NotFoundException

Try Handling Exception Using:

@ControllerAdvice
@RestController
public class CustomizedResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

  @ExceptionHandler(StudentNotFoundException)
  public final ResponseEntity<ErrorDetails> handleUserNotFoundException(StudentNotFoundException ex, WebRequest request) {
    ErrorDetails errorDetails = new ErrorDetails(new Date(), ex.getMessage(),
        request.getDescription(false));
    return new ResponseEntity<>(errorDetails, HttpStatus.NOT_FOUND);
  }
