用Socket 实现两台机子上的两个文件时实同步,可以注入到WIN服务运行

网上查了半天,没好的同步软件,故自己写了个

当需要同步的文件一有改变,目的文件能马上更新

SOCKET实现,公司要用的小程序

可以自己配制IP,端口,文件名.

在config.properties中配制

能注入WIN服务,但必须先启动服务端再启动客户端

注入WIN服务,需要下载个文件 JavaService.exe

 

客户端 批处理文件

JavaService.exe -install 同步文件客户端 D:/JDK/jre/bin/server/jvm.dll -Djava.class.path=D:/JDK/lib/tools.jar;E:/报表程序/tongbu/bin -start Client

 

服务端 批处理文件

JavaService.exe -install 同步文件服务端 D:/JDK/jre/bin/server/jvm.dll -Djava.class.path=D:/JDK/lib/tools.jar;E:/报表程序/tongbu/bin -start Server

 

目录结构如下:

D:/TONGBU
└─bin
    └─com
        └─xy
            ├─dao
            └─tool
