最近的项目在整长连接WebSocket，之前也写过一个感觉没有这个全面。提供个工具类
WebSocketHelper
和
Java-WebSocket-1.3.9.jar包
以及一个
HttpURLConnectionUtil
1、WebSocketHelper

import org.java_websocket.drafts.Draft_6455;
import org.java_websocket.handshake.ServerHandshake;
import java.net.URI;
import java.util.Date;
import java.util.concurrent.TimeUnit;

3、
Java-WebSocket-1.3.9.jar包（上传的是个压缩包，直接解压就能用）
