Extending payment validation

In order to extend payment validation with custom bank’s requirements, one needs to override:

• DefaultPaymentValidationConfigImpl with custom ValidationObject fields (Occurrence and max length);

• DefaultPaymentBodyFieldsValidatorImpl with overridden method createPaymentValidationConfig (put there custom DefaultPaymentValidationConfigImpl extension);

• DefaultPaymentValidatorHolder with passing custom extended DefaultPaymentBodyFieldsValidatorImpl in constructor parameters and overridden method isCustom (return true here);

• CustomPaymentValidationService with annotation @Primary and override needed methods according to bank’s requirements. Use ErrorBuildingService to enrich message error.
