我无法通过Java websocket客户端连接到我的websocket服务器

我无法通过Java websocket客户端连接到我的websocket服务器。请帮助！ 正在使用ApacheTomcat 8.0.26 将异常获取为“java.io.IOException”：尝试对非套接字的对象执行操作

客户端类 导入java.io.IOException； 导入java.io.OutputStream； 导入java.net.HttpURLConnection； 导入java.net.URI； 导入java.net.URL； 导入java.util.concurrent.CountDownLatch
