我正在用我们的tomcat服务器做压力测试，它通过WebSocket技术与客户端通信。所以当我在客户端尝试超过150个并发用户时，我收到了这个异常，我不知道服务器想说什么。

最可能的原因是你可能没有客户端URL没有“WebSocket”像：
“ws：//"+HOST+"：“+ PORT+"/WebSocket”
如果在与服务器通信时在客户端代码中遗漏了/WebSocket，则会出现此异常

您必须遵循与浏览器客户端相同的规则
在你的客户端，你可以添加下面的代码
$mysql. println（）;
同样的你必须做你的java客户端也，因为你的请求没有订阅大气，大气是不authenate你的请求.在java端首先你做大气连接，然后你必须发射你的请求...
