是否可以在两个类之间使用RMI双向？ [英] Is it possible to use RMI bidirectional between two classes?

问题描述

我想在两个类（A和B）之间共享一些信息，这些类在不同的Java程序中运行。而不是编写一个完整的通信协议，我想使用java内置的rmi类的目的。目前B类能够远程运行属于A类的方法。是不是有可能在类A中使用相同的连接来调用类B的方法？否则我可能需要实现第二个rmi服务...

I want to share some information between two classes (A and B), which are running in different java programs. Instead of writing a whole communication protocol I want to use the java build-in rmi classes for that purpose. Currently class B is able to run a method which belongs to class A remotely. Is it somehow possible to use the same "connection" within class A to call a method of class B? Otherwise I probably have to implement a second rmi service ...

BR，

推荐答案

如果 B 实现远程，它可以导出并作为参数在RMI调用中传递给 A 。在这种情况下，不需要在RMI注册表中注册 B ，因为客户端明确地传递了对它的引用。

If B implements Remote, it can be export and passed as a parameter in an RMI call to A. In this scenario, there's no need to register B in an RMI registry, since the client is being passed a reference to it explicitly.
