InvocationHandler handler = new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) {
if (method.getName().equals("speak")) {
System.out.println("准备");
System.out.println(args[0]);
System.out.println("结束");
}
return null;
}
};
Person person = (Person) Proxy.newProxyInstance(
1,
2,
handler);
person.speak("你好，很高兴认识你。");
}
}
