I want to get the parameter name through
MethodArgumentNotValidException ex.getBindingResult().getFieldError() where I've applied a custom annotation to class level. How can i do this ?

I've tried to get it to a list of fieldErrors. But it doesn't work.

CustomFieldValidator class

public CustomFieldValidator implements ConstraintValidator<CustomFieldConstraint, Object> 

 private String baseFieldName;
 private String[] dependedFields;
 private List<Object> conditionalValuesList;
 private List<Object> expectedValuesList;

 @Override
 public void initialize(final CustomFieldConstraint constraintAnnotation) 
 this.baseFieldName = constraintAnnotation.baseField();
 this.dependedFields = constraintAnnotation.dependedFields();
 this.conditionalValuesList = new ArrayList<>(Arrays.asList(constraintAnnotation.conditionValues()));
 this.expectedValuesList = new ArrayList<>(Arrays.asList(constraintAnnotation.expectedValues()));
 

Below is the ExceptionHandlerController class

 @ResponseStatus(HttpStatus.BAD_REQUEST)
 @ResponseBody
 public InErrorResponse handleMethodArgumentNotValid(MethodArgumentNotValidException ex,
 MultipleReadHttpRequest request) {

 BindingResult result = null;
 List<FieldError> fieldErrors = null;

 result = ex.getBindingResult();
 fieldErrors = result.getFieldErrors();

This is how I've included the custom annotation in domain class

@CustomFieldConstraint(baseField = "deviceXyz", conditionValues = "02" , dependedFields = 
 "eDSRequestorXyz" )
public class InAXyz 

java spring spring-boot
