分享webSocket如何部署端点
这是端点：
@ServerEndpoint("/echo")
public class EchoServer {
@OnMessage
public String echo(String incomingMessage ){
return "I got this (" + incomingMessage + ")"
+ " so I am sending it back !";
}
客户端：

echo_websocket = new WebSocket(wsUri);

function writeToScreen(message){
var pre = document.createElement("p");

如果想从服务器端推送消息到客户端的话，个人觉得GoEasy推送还不错，它有Restful API 支持多语言，而且针对java他们还特别做了SDK,使用很简单方便。同时它也支持客户端推送。由于它支持websocket 和polling两种连接方式所以兼顾大多数主流浏览器，低版本的IE浏览器也是支持的，很适合需要快速建立实时web通信的项目。https://goeasy.io
