是什么让 rmi 服务器继续运行? [英] what make rmi server keep running?

问题描述

我有以下 RMI 服务器代码:

I have the following RMI server code:

public class ServerProgram {
    public ServerProgram() {
        try {
            LocateRegistry.createRegistry(1097);
            Calculator c = new CalculatorImpl();
            String name = "rmi://host:port/name";
            Naming.rebind(name, c);
            System.out.println("Service is bound......");
        } catch (Exception e) {
        }
    }
    public static void main(String[] args) {
        new ServerProgram();
    }
}

当上述程序运行时，它会一直运行以等待客户端请求.但我不明白的是，是什么让该程序在不在 while(true){}; 之类的情况下继续运行，以及如何阻止它监听，除了停止整个程序?>

When the above program running, it keeps running to wait for client requests. But what I do not understand is what make that program keeps running while it is not in something like while(true){}; and how to stop it from listening, except stopping the whole program?

推荐答案

让它一直运行的是一个由 RMI 启动的非守护进程监听线程.要使其退出，请使用 UnicastRemoteObject.unexportObject() 取消绑定名称并取消导出注册表和远程对象.

What makes it keep running is a non-daemon listening thread started by RMI. To make it exit, unbind the name and unexport both the Registry and the remote object, with UnicastRemoteObject.unexportObject().
