Spring RMI (Spring 远程方法调用)【原】

所需jar包...?    不纠结,一股脑儿全导! 源码地址:http://pan.baidu.com/s/1jG8eOmy

先放结构图如下,客户端和服务端都在一个项目中.也可以把服务端的xxx导成jar包放到新的客户端项目中去.

其中绿色部分为服务器端代码, 红色部分为客户端代码.

现在是服务/客户端全整到一块去的项目,如果要把客户端独立出来,可以把绿色服务器端代码导成jar包放到单独的客户端项目中,用Client.java进行调用.

Client.java:                              客户端入口调用类

Car.java:                                 POJO类(C/S共用)

IKeyboard.java:                       RMI 接口类(C/S共用)

Keyboard.java:                        RMI实现类

IVehicle.java:                           RMI接口类(C/S共用)

Vehicl:                                    RMI实现类

remote-client-local.xml:             客户端spring配置文件

remote-servlet.xml:                  服务端spring配置文件

客户端打印:

success
该车状态(检测前):未检测
该车状态(检测后):99% is ok

服务端打印:

press------
i'm logitech keyboard,press twice
leave------
start detect------
该车信息Car [id=6, model=宝马M6, speed=320公里/小时, result=未检测]
end detect------
