Question

嗯..在某些情况下，我有一个需要在hazelcast实例上进行操作的Object。所以我实现了HazelcastInstanceAware接口，但这似乎不适用于嵌套类......

以下核心向控制台输出“null”：

public class NullError实现Serializable，HazelcastInstanceAware { 私有瞬态HazelcastInstance instance1; 私有瞬态HazelcastInstance instance2;

public static void main(String[] args) throws Exception {
    //new NullError().test();
    new NullError().lala();
}

private void lala() throws Exception {
    instance1 = Hazelcast.newHazelcastInstance();
    instance2 = Hazelcast.newHazelcastInstance();

    IMap<Object, Object> foo = instance1.getMap("foo");
    foo.put("foo", new Foo(instance1));

    ((Callable) instance2.getMap("foo").get("foo")).call();
}

public static class Foo implements Serializable, Callable {
    public Bar bar;

    public Foo(HazelcastInstance instance) {
        bar = new Bar(instance);
    }

    @Override
    public Object call() throws Exception {
        return bar.call();
    }
}

public static class Bar implements Callable, Serializable, HazelcastInstanceAware {
    private transient HazelcastInstance i;

    public Bar(HazelcastInstance instance) {
        this.i = instance;
    }

    @Override
    public void setHazelcastInstance(HazelcastInstance instance) {
        this.i = instance;
    }

    @Override
    public Object call() throws Exception {
        System.out.println(i);
        return null;
    }
}

}

文档中没有提到HazelcastInstanceAware只能应用于根对象..任何想法？这是一个Bug吗？

Answer 1

HazelcastInstanceAware仅适用于要反序列化的根对象。我们不会查看实现此接口的实例的对象图。

HazelcastInstanceAware不适用于嵌套对象
