publicWheel(){

this.texture=texture;
publicSofa(){
super();
this.color="white";
this.count=4;
this.texture="fur";
classCar{
privateWheelwheel;
privateSofasofa;
publicWheelgetWheel(){
returnwheel;
voidsetWheel(Wheelwheel){
this.wheel=wheel;
publicSofagetSofa(){

classTest{

map.put("car1",newCar());
map.put("car2",153); font-weight:bold; background-color:inherit">newCar());
//需要过滤的类+属性
Map<Class<?>,Set<String>>includeMap= Set<String>set=newHashSet<String>();
set.add("color");
includeMap.put(Wheel.class,set);
