如何自动将所有嵌套的静态类作为参数传递到方法调用中

Question

有没有办法检索Network类(定义如下(中的静态类数组，并将每个类的属性class传递到方法调用kryo.register的参数中？

public class Network {
    // Classes to be transferred between the client and the server
    public static class A {
        public int id;
        public String name;
    }
    public static class B {
        public int id;
        public int x;
        public int y;
    }
    // Rest of the classes are defined over here
    static public void register(EndPoint endPoint) {
        Kryo kryo = endPoint.getKryo();
        // typical way of registering classes so that kryonet can use it
        // kryo.register(A.class);
        // kryo.register(B.class);
        // the rest of the classes are registered with kryonet over here
        // my attempt at solving the question,
        // but for some reason this doesn't work?
        for(Object o : Network.class.getDeclaredClasses()) {
            kryo.register(o.getClass());
        }
    }
}

Answer 1

问题是你正在使用类的类，这不是你想要的。 如果对getDeclaredClasses()调用的结果使用正确的类型，则会更明显：

    for(Class<?> c : Network.class.getDeclaredClasses()) {
        kryo.register(c);
    }

(顺便说一句，您已经在使用反射 -> getDeclaredClasses() (。
