我正在运行 java RMI 的 Hello World 示例
1）我在一个空文件夹中运行注册表
motta@motta-laptop ~/tmp $ rmiregistry
2) 我启动 HTTP 服务器以在运行时检索类。下载文件夹包含客户端-服务器的远程接口
motta@motta-laptop ~/download $ java NanoHTTPD 8080
3）我启动服务器传递 java.rmi.server.codebase 属性，如 java RMI 教程中所建议的那样
motta@motta-laptop ~/server $ java -Djava.rmi.server.codebase="http://localhost:8080" WarehouseServer
RMI 注册表没有联系 HTTP 服务器并且正在引发异常（请参阅问题后的详细信息）。 但是，如果我执行以下操作
1) 使用 java.rmi.server.codebase 属性启动 rmi 注册表
motta@motta-laptop ~/tmp $ rmiregistry -J-Djava.rmi.server.codebase="http://localhost:8080/"
2）像以前一样启动HTTP服务器
3）不带任何选项启动服务器
motta@motta-laptop ~/server $ java WarehouseServer
它有效，但为什么呢？似乎在第一个过程中，RMI 注册表忽略了 java.rmi.server.codebase 属性
谢谢
