我有以下具体课程:
public class A1 {}
public class B1 extends A1 {}
public class A2 {}
public class B2 extends A2 {}
public class B3 extends A2 {}
我希望在映射MapperFacade.map(b1Instance, A2.class)
我需要这个,因为A2有很多子类型(如图所示的B2和B3),我需要在需要时映射适当的子类型
是否有可能通过Orika实现这一目标?
答案 0 :(得分:0)
对于将面临同样问题的人,我解决了这个问题,创建了一个这样的CustomMapper来验证哪个是要实例化的子类型
mapperFactory.classMap(SOURCE.class, DEST.class)
.customize(new CustomMapper<SOURCE, DEST>() {
@Override
public void mapAtoB(SOURCE source, DEST dest, MappingContext context) {
//verifies the type to instantiate
private A2 a2 = isB2() ? new B2() : new B3;
//use the mapper for the class (will use the B2 or B3 mapper)
mapperFacade.map(source.getA2(), a2);
// set the field into the dest object
dest.setB1(a2);
}
}
