Java WebSocketClient 做本地数据接收处理服务程序

Client是基本类

WebSocketClientTest是主方法入口

maven 地址,可能还需要其他的包等会截图

这里只贴webSocket的主要代码,其他关于业务逻辑的,JDBC的就不在贴上面了

需要注意下的是关于用Eclipse打jar包,

我用的是 Eclipse Java EE IDE for Web Developers.

Version: Mars Release (4.5.0)

按照网上装fatjar死活装不上,原因居然是用错包了,这里特此吐槽下需要用net.sf.fjep.fatjar_0.0.32.jar

0.0.32的版本亲测可用,网上一般都是0.0.31的是可能装了没反应

下面是关于安装和使用的链接

打完jar包后就可以 cmd java -jar xxxx/jar去运行了
