问答 WebSocket本地调试没问题，Jetty部署后可以连接但无法使用房间功能

具体情况是这个web应用在本地调试没有任何问题，放在服务器里的话，虽然也可以连接的上，但是同样的请求却没有反应
比如在客户端发送指令

{"room":"22","action":"join"}

本地日志

就是无论怎么发送都没反应，而且没效果

但是如果使用@onMessage注解就可以获取发送的消息

这是代码

package ycu.ktv.module;

@ServerEndpoint(value = "/websocket", configurator = NutWsConfigurator.class)
@IocBean // 使用NutWsConfigurator的必备条件
public class WebSocketModule extends AbstractWsEndpoint {
    @Override
    public WsHandler createHandler(Session session, EndpointConfig config) {
        return new MySimpleWsHandler();
    }
    

    public class MySimpleWsHandler extends SimpleWsHandler {
        public MySimpleWsHandler() {
            super(""); // 覆盖默认前缀
        }

        public void msg2room(final NutMap req) {
            final String room = req.getString("room");
            if (room != null) {
                String _room = room;
                if (this.prefix.length() > 0 && !room.startsWith(this.prefix)) {
                    _room = this.prefix + room;
                }

                this.endpoint.each(_room, new Each<Session>() {
                    public void invoke(int index, Session ele, int length) {
                        if (!ele.getId().equals(MySimpleWsHandler.this.session.getId())) {
                            NutMap resp = new NutMap("action", "msg");
                            resp.setv("room", room);
                            resp.setv("timestamp", System.currentTimeMillis());
                            resp.setv("msg", req.get("msg"));
                            if (MySimpleWsHandler.this.nickname != null) {
                                resp.setv("nickname", MySimpleWsHandler.this.nickname);
                            }

                            MySimpleWsHandler.this.endpoint.sendJson(ele.getId(), resp);
                        }
                    }
                });
            }
        }

    }
}

websocket插件使用版本 1.r.63.r5

覆盖一下OnMessage方法，加点日志看看

还有一种可能性是老版本的jar存在

复写了onMessage日志还是一样的效果
这是代码

package ycu.ktv.module;

@IocBean // 使用NutWsConfigurator的必备条件
public class WebSocketModule extends AbstractWsEndpoint {
    @Override
    public WsHandler createHandler(Session session, EndpointConfig config) {
        return new MySimpleWsHandler();
    }

    public class MySimpleWsHandler extends SimpleWsHandler {
        public MySimpleWsHandler() {
            super(""); // 覆盖默认前缀
        }

        @Override
        public void onMessage(String message) {
            super.onMessage(message);
            System.out.println("onMessage " + message);
        }

        public void msg2room(final NutMap req) {
            final String room = req.getString("room");
            if (room != null) {
                String _room = room;
                if (this.prefix.length() > 0 && !room.startsWith(this.prefix)) {
                    _room = this.prefix + room;
                }

                this.endpoint.each(_room, new Each<Session>() {
                    public void invoke(int index, Session ele, int length) {
                        if (!ele.getId().equals(MySimpleWsHandler.this.session.getId())) {
                            NutMap resp = new NutMap("action", "msg");
                            resp.setv("room", room);
                            resp.setv("timestamp", System.currentTimeMillis());
                            resp.setv("msg", req.get("msg"));
                            if (MySimpleWsHandler.this.nickname != null) {
                                resp.setv("nickname", MySimpleWsHandler.this.nickname);
                            }

                            MySimpleWsHandler.this.endpoint.sendJson(ele.getId(), resp);
                        }
                    }
                });
            }
        }

    }
}

如果是有老版本的jar那该怎么处理呢，我这边是使用war包部署的

WebSocketModule的onMessage方法

还是和上面的日志一样没有反应
这是代码

package ycu.ktv.module;


import org.nutz.ioc.loader.annotation.IocBean;
import org.nutz.lang.Each;
import org.nutz.lang.util.NutMap;
import org.nutz.plugins.mvc.websocket.AbstractWsEndpoint;
import org.nutz.plugins.mvc.websocket.NutWsConfigurator;
import org.nutz.plugins.mvc.websocket.WsHandler;
import org.nutz.plugins.mvc.websocket.handler.SimpleWsHandler;

import javax.websocket.EndpointConfig;
import javax.websocket.OnMessage;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

// ServerEndpoint是websocket的必备注解, value是映射路径, configurator是配置类.
@ServerEndpoint(value = "/websocket", configurator = NutWsConfigurator.class)
@IocBean // 使用NutWsConfigurator的必备条件
public class WebSocketModule extends AbstractWsEndpoint {
    @Override
    public void onMesssageString(Session session, String msg) {
        super.onMesssageString(session, msg);
        System.out.println("session" + session + "   " + "msg" + msg);
    }

    @Override
    public WsHandler createHandler(Session session, EndpointConfig config) {
        return new MySimpleWsHandler();
    }

    public class MySimpleWsHandler extends SimpleWsHandler {
        public MySimpleWsHandler() {
            super(""); // 覆盖默认前缀
        }

        public void msg2room(final NutMap req) {
            final String room = req.getString("room");
            if (room != null) {
                String _room = room;
                if (this.prefix.length() > 0 && !room.startsWith(this.prefix)) {
                    _room = this.prefix + room;
                }

                this.endpoint.each(_room, new Each<Session>() {
                    public void invoke(int index, Session ele, int length) {
                        if (!ele.getId().equals(MySimpleWsHandler.this.session.getId())) {
                            NutMap resp = new NutMap("action", "msg");
                            resp.setv("room", room);
                            resp.setv("timestamp", System.currentTimeMillis());
                            resp.setv("msg", req.get("msg"));
                            if (MySimpleWsHandler.this.nickname != null) {
                                resp.setv("nickname", MySimpleWsHandler.this.nickname);
                            }

                            MySimpleWsHandler.this.endpoint.sendJson(ele.getId(), resp);
                        }
                    }
                });
            }
        }

    }
}

本地也是war部署？

还原一下，把本地跟服务器的部署统一起来试试

刚刚测试了jetty服务器在本地可以运行，同样的文件夹复制到服务器里就不行了
最后换了tomcat服务器配置成功了，谢谢大佬！

好的, 这个websocket真的有点麻烦...
