映射时将外部数据添加到Orika MappingContext

Question

我想在MappingContext中添加一些外部属性(不在我正在映射的对象中).

这就是我想要完成的事情:

    MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
    mapperFactory.classMap(ObjA.class, ObjB.class).customize(new CustomMapper<ObjA, ObjB>() {
        @Override
        public void mapAtoB(ObjA objA, ObjB objB, MappingContext context) {
            objB.setName((String) context.getProperty("name"));
        }
    }).byDefault().register();
    MapperFacade mapper = mapperFactory.getMapperFacade();

    ObjA objA = new ObjA();
    ObjB objB = new ObjB();

    MappingContext context = new MappingContext(); //PROBLEME IS HERE: MappingContext is a abstract class
    context.setProperty("name", "Some information not in objA nor in objB");
    mapper.map(objA, objB, context);

我怎样才能做到这一点？我可以动态地将数据添加到上下文中吗？或者它是将其他数据传递给映射器的另一种方法？

解决方案很简单:

MappingContext context = new MappingContext.Factory().getContext();
context.setProperty("name", "value");
mapper.map(objA, objB, context);
