就是说 我在本地开了三个页面 叫小A 小B 小C
但是在小B加入时 没有通知给小A, 而是在小B的页面通知了两条
在小C加入时,没有通知A和B,而是在C的页面通知了三条

发消息也是一样 此时A发消息 只会在C的页面弹出三条

然后在C关闭页面时,报NPE

不能是同一个Cookie域下啊，你得开不同的浏览器，或者开谷歌的无痕模式，也是处于不同的Cookie下了，这就和你登录两个淘宝京东网站，一样的帐号一样，理解了没

不过我这里没有继续写下去，还可以优化下

  1. 消息可以直接放后台应用里持久化
  2. 前端打开新窗口也应该判断是否存在

我只是写个小例子记录下，这个框架直接封装了，很简单的用就行，我打算接下来要用Netty去实现，都是菜鸟，共勉
