我试图用orika将字符串Map到uuid，但出现以下错误：
发生sourcetype=java.lang.string destinationtype=java.util.uuid错误：没有为从字符串到uuid的转换注册转换器，也没有任何可以从字符串生成uuid的objectfactory

public class SourceType {
    private String firstId;

  //setters getters
}

public class DestinationType {
    private UUID firstId;
  //setters getters
}

mapperFactory.classMap(SourceType.class, DestinationType.class)
                .byDefault()
                .customize(new MyCustomMapper())
                .register();

private final class MyCustomMapper extends CustomMapper<SourceType, DestinationType> {
        @Override
        public void mapAtoB(final SourceType sourceType, final DestinationType destinationType, final MappingContext context) {
             destinationType.setFirstId(UUID.fromString(sourceType.getFirstId()));
    }
}
