java - Orika:将常量默认值映射到字段

Question

有没有办法使用 Orika将字段的值设置为文字值或常量值？

我的意思是:

public class ObjectMapper extends ConfigurableMapper {

        protected void configure(MapperFactory factory) {
             factory.classMap(SourceClass.class, DestinationClass.class)
             .field("myField", "CONSTANT_VALUE")
             .byDefault()
             .register();
        }
}

我在文档中找不到类似的东西...

根据 this section在 Orika 文档中，设置文字值的唯一方法是自定义映射。例如:

public class ObjectMapper extends ConfigurableMapper {

        protected void configure(MapperFactory factory) {
             factory.classMap(SourceClass.class, DestinationClass.class)
             .byDefault()
             .customize(new CustomMapper<SourceClass, DestinationClass>() {
                @Override
                public void mapAtoB(SourceClass a, DestinationClass b, MappingContext context) {
                    b.setMyField("CONSTANT_VALUE");
                }

                // ...
            })
            .register();
        }
}
