Question

我正在尝试使用@ClientEndpoint为WebSocket编写一个java客户端。服务器端点工作正常，因为我能够通过浏览器（JavaScript客户端）连接到它。但是每当我尝试使用java客户端连接到它时，我都会得到以下异常，但它并没有透露太多关于它自身的信息。只是添加信息相同的项目在我的个人笔记本电脑上工作正常。然而，它在我的工作系统中失败了（可能是一些防火墙，但在这种情况下，我认为它应该作为javascript客户端失败）。

技术堆栈：Java 7，Tomcat 8 / Weblogic

修改只是为了更新，使用 tyrus独立jar 我现在甚至可以从java客户端连接到WebSocket。但是当我通过Apache Tomcat 8连接时，问题仍然存在。

执行：

这是抛出错误的代码

@ClientEndpoint public class MovieEventSocketClient {   public MovieEventSocketClient(URI endpointURI) {        try {
        WebSocketContainer container = ContainerProvider
                .getWebSocketContainer();
        container.connectToServer(MovieEventSocketClient.class, endpointURI);
    } catch (Exception e) {
        e.printStackTrace();
        throw new RuntimeException(e);

    }
}
