【问题描述】：
我正在尝试在 Wildfly 上部署一个包含 WebSocket 端点的应用程序，但出现此错误：
javax.websocket.DeploymentException: UT003012: 方法公共无效 Endpoint.openConnection(javax.websocket.Session,javax.websocket.EndpointConfig,java.lang.String) 有无效参数 [2]"}}
这是端点类的代码：
import javax.websocket.EndpointConfig;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
import javax.ws.rs.PathParam;
@ServerEndpoint(value = "/update-user/{token}")
public class UpdateUsersEndpoint {
@OnOpen
public void openConnection(Session session, EndpointConfig config, @PathParam("token") String token) {
...
}
@OnClose
public void closedConnection(Session session, CloseReason reason, @PathParam("token") String token) {
...
}
}
这是 Wildfly 日志的完整堆栈：

删除最后两个参数后部署成功。
由于WebSocket JSR 声明使用@OnOpen 注释的方法可以具有我的方法中的参数，我不明白为什么Wildfly 拒绝部署应用程序。

【问题讨论】：
-
你的 WEB-INF/lib 是什么样的？

谢谢@ctomc 我已经编辑了答案，添加了 WEB-INF/lib 文件夹。
