我有一些 Soap、REST servlet，现在还有一个 WebSocket：
@ServerEndpoint("/game")
public class WebSocketgame{
...
}
我有下一个麻烦：如果 web.xml 存在，WebSocket 不可见。在 web.xml 中描述 jdbc 资源、servlet 和其他...
当我删除 web.xml - websocket 成功可见。我该如何解决这个问题？
更新 web.xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

尝试添加

在 beans.xml 文件中
