Spring IOC循环依赖问题

A对象引用B对象

B对象引用A对象

spring中采用三级缓存来解决：

    private final Map<String, ObjectFactory<?>> singletonFactories = new HashMap(16);

简易代码：

public static void main(String[] args) {
        HashMap hashMap = new HashMap();//缓存未赋值的对象 对应spring中的三级缓存
        hashMap.put("aobj",new Aobj());
        hashMap.put("bobj",new Bobj());

        //相互依赖
        Aobj aobj = (Aobj) hashMap.get("aobj");
        Bobj bobj = (Bobj) hashMap.get("bobj");
        aobj.setBobj(bobj);
        bobj.setAobj(aobj);

        System.out.println();
    }

效果:
