java - rmi 注册表 : best way to assure there's one running?

Question

我遗漏了一些关于

1. 在命令提示符下启动 rmiregistry(独立于运行实现 RMI 接口(interface)的服务器的任何 Java 进程)
2. 让服务器调用LocateRegistry.getRegistry()
3. 让服务器调用LocateRegistry.createRegistry(Registry.REGISTRY_PORT)

我只希望我的服务器将其导出的对象注册到注册表，如果还没有运行则创建一个。执行此操作的最佳方法是什么？

Answer 1

旧线程但是...

man rmiregistry

说:

The methods of the java.rmi.registry.LocateRegistry class are used to get a registry operating on the local host or local host and port.

否则你有:

The URL-based methods of the java.rmi.Naming class operate on a registry and can be used to look up a remote object on any host and on the local host

所以我想这就是重要的区别。另一件事是 SecurityManager 和策略。
