Play Framework无法连接到WS

标签： java playframework playframework-2.4

我正在尝试为我的Play应用程序提供WebSocket连接，但是即使使用示例代码我也遇到了问题。 使用websocket echo页面，我尝试发送数据。但是，我甚至无法连接。

我有一个控制器，我有样本public WebSocket<String> socket() 在我的路线文件中，我有GET /socket @controllers.Application.socket()

使用URL时：ws：// localhost：9001 / socket没有任何反应 当使用wss：// localhost：9001 / socket时，我得到netty错误而没有真正的信息。

我很遗憾地不知道该怎么办。如果需要，我可以提供更多代码，这是来自Play文档页面的示例代码。

问题是因为我在HTTPS中使用了echo测试。一旦我将其更改为HTTP，一切正常。
