class MyInvocationHandler implements InvocationHandler{
private static Service targetService;
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
return null;
}
public static Service getProxyService(Service target){
targetService = target;
ClassLoader contextClassLoader = Thread.currentThread().getContextClassLoader();
Class<?>[] interfaces = targetService.getClass().getInterfaces();
return (Service)Proxy.newProxyInstance(contextClassLoader,interfaces,new MyInvocationHandler());
}}

还是直接用匿名内部类吧
Service proxyInstance = (Service) Proxy.newProxyInstance(target.getClass().getClassLoader(),
target.getClass().getInterfaces(), new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
if ("add".equals(method.getName())) {
System.out.println("HELLOIDEA");
}
return null;
}
});
proxyInstance.add();
