如何避免 Java RMI 的 MarshalException？
我刚刚用 java rmi 完成了一个小程序，但不知何故它不起作用。每次我想启动服务器时，我都会收到 MarshalException。关于如何实现远程方法调用的接口，我应该注意哪些要点？我认为可以创建一个实现，但也可以在实现类中包含一些附加方法，例如构造函数或私有变量。
这不应该有效吗？
问候
I just finished a small program with java rmi and somehow it doesn't work. Everytime I want to start the server I'm getting the MarshalException. Are there any important points that I should be aware of them on how to implement the interface for the remote method invocation? I thought it would be possible to create an implementation but also include some additional methods like a constructor or private variables inside of the implementing class.
Shouldn't this just work?
Greetings

为了能够传输对象，您需要使它们实现
Serialized。也许有一个默认的（无参数）构造函数（但这不是序列化的要求）正如helios指出的，不仅是类，而且所有字段层次结构（字段的类及其字段的类）都必须是<代码>可序列化）
In order to be able to transfer objects you need to make them implement
Serializable. And perhaps have a default (no-arg) constructor (this is not a requirement for serialization though)As helios noted, not only the class, but all your field hierarchy (classes of fields, and the classes of their fields) must be
Serializable)这就是你的问题。客户端需要该类。
There's your problem. That class is required at the client.
