Java에서 인터페이스 및 추상 클래스의 반사 메커니즘 구현

Class<?> interfaceClass = Class.forName("com.example.MyInterface");

System.out.println("Interface name: " + interfaceClass.getName());

// 获取接口的所有方法
Method[] methods = interfaceClass.getMethods();
for (Method method : methods) {
    System.out.println("Interface method: " + method.getName());
}

Class<?> abstractClass = Class.forName("com.example.MyAbstractClass");

System.out.println("Abstract class name: " + abstractClass.getName());

// 获取抽象类的所有方法
Method[] methods = abstractClass.getMethods();
for (Method method : methods) {
    if (!method.isAbstract()) {
        System.out.println("Non-abstract method in abstract class: " + method.getName());
    }
}

// 为 MyInterface 创建一个动态代理
InvocationHandler handler = new MyInvocationHandler();
Class<?> proxyClass = Proxy.getProxyClass(interfaceClass, handler);
MyInterface proxy = (MyInterface) proxyClass.newInstance();

// 使用代理调用接口方法
proxy.someMethod();
