Unable to inject EJBTransactionRolledbackException - spring

Question

I am not able to inject EJBTransactionRolledbackException. I want to catch ConstraintViolationException. So first I need catch EJBTransactionRolledbackException then I can propagate to ConstraintViolationException exception using getCause().
How to inject it?
Below is my code.
#ControllerAdvice
public class RestExceptionProcessor extends ResponseEntityExceptionHandler {
// Here I am not able to inject EJBTransactionRolledbackException.
#ExceptionHandler({EJBTransactionRolledbackException.class})
protected ResponseEntity<Object> handleUniqueKeyViolation(EJBTransactionRolledbackException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
Throwable t = ex.getCause();
if(t != null &(t instanceof RollbackException)){
if(t != null &(t instanceof ConstraintViolationException)) {
return handleConstraintViolation((ConstraintViolationException) ex.getCause(), headers, status, request);
}
return handleConstraintViolation((RollbackException) ex.getCause(), headers, status, request);
}
String error = ex.getLocalizedMessage() + " " + ex.getMessage();
ApiError apiError = new ApiError(HttpStatus.BAD_REQUEST, ex.getLocalizedMessage(), error);
return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus());
}
#ExceptionHandler({RollbackException.class})
protected ResponseEntity<Object> handleConstraintViolation(RollbackException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
String error = ex.getLocalizedMessage() + " " + ex.getMessage();
ApiError apiError = new ApiError(HttpStatus.CONFLICT, ex.getLocalizedMessage(), error);
return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus());
}
#ExceptionHandler({ConstraintViolationException.class})
protected ResponseEntity<Object> handleConstraintViolation(ConstraintViolationException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
List<String> errors = new ArrayList<String>();
for (ConstraintViolation<?> violation : ex.getConstraintViolations()) {
errors.add(violation.getRootBeanClass().getName() + " " +
violation.getPropertyPath() + ": " + violation.getMessage());
}
ApiError apiError = new ApiError(HttpStatus.CONFLICT, ex.getLocalizedMessage(), error);
return new ResponseEntity<Object>(apiError, new HttpHeaders(), apiError.getStatus());
}
}
And my ApiErrors class is like below:
public class ApiError {
private HttpStatus status;
private String message;
private List<String> errors;
public ApiError(HttpStatus status, String message, List<String> errors) {
super();
this.status = status;
this.message = message;
this.errors = errors;
}
public ApiError(HttpStatus status, String message, String error) {
super();
this.status = status;
this.message = message;
this.errors = Arrays.asList(error);
}
}
