spring RMI demo运行报错-nested exception is java.rmi.ConnectException: Connection refused to host: local

报错提示：nested exception is java.rmi.ConnectException: Connection refused to host:
localhost; 

还原环境：测试 spring RMI ，部署了两个 service，一个 web ，运行 web 测试 service2 报错

原因分析：之前自己只是运行了service 1 的 主程序，没有运行service 2

解决办法：运行service 2 的 服务程序

下附具体报错：
