问答 Nutz 和 Websocket 怎么跑起来?
发布于 2791天前 作者 qq_b21b7504 2330 次浏览 复制 上一个帖子 下一个帖子
标签: nutzwk

参考了下nutz的过往 demo, 在 MainSetup 下 

	ServerContainer sc = (ServerContainer) config.getServletContext().getAttribute(ServerContainer.class.getName());
			if (sc != null)
				try {
					sc.addEndpoint(MyWebsocket.class);
				} catch (Exception e) {
					e.printStackTrace();
				}

报错,java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to javax.websocket.server.ServerContainer
各位,如何解决?

tomcat8

http://nutzam.com/core/mvc/websocket.html

赞！！ 有新方式了

按照最新的配置 

ws = new WebSocket("ws://"+WS_URL);   //这一行

F12 报错
WebSocket connection to 'ws://localhost:8001/sms%20/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404

使用 websocket 在线测试 网页 连接 报错

org.nutz.mvc.impl.UrlMappingImpl.get(UrlMappingImpl.java:110) DEBUG - Search mapping for [GET] path=/websocket : NOT Action match

请求被MVC拦截了?

tomcat8才行的

@wendal 大神 确确实实在tomcat8跑得呀 Nutz的包 用的是1.r.60 nutz-plugins-websocket 使用的是 1.r.61.r2 这会有影响吗?

http://nutzam.com/core/mvc/websocket.html 按上面的做, 并不需要 sc.addEndpoint

@wendal 嗯 我确实是按照文档上面来的呀 只配置了 MyWebsocket 这一个类 其他的都清了 还是报错 404

启动日志发一下

@wendal 请指教 = =!

难道没扫描到??

	                ServerContainer sc = (ServerContainer) config.getServletContext().getAttribute(ServerContainer.class.getName());
			if (sc != null)
				try {
					sc.addEndpoint(MyWebsocket.class);
				} catch (Exception e) {
					e.printStackTrace();
				}

看看报啥

用的是maven吗？ pom.xml贴一下看看

@wendal MainSetUp 添加

还是报错 转换异常 

java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer cannot be cast to javax.websocket.server.ServerContainer

@wendal pom 奉上

然后是 启动日志里 , MyWebsocket启动了

2017-05-02 17:19:02,563 org.nutz.ioc.loader.annotation.AnnotationIocLoader.addClass(AnnotationIocLoader.java:74) DEBUG - Found @IocBean : class com.bsdkj.sms.modules.service.Message.MyWebsocket

加scope

                        <scope>provided</scope>
		</dependency>

@qq_b21b7504 另外，那不是启动，那是ioc的日志

@wendal 跑起来了
websocket这个类 ioc 注入了 根据文档 不就代表websocket能建立连接了吗?

@qq_b21b7504 不是哦，那只是提供ioc支持的日志

@wendal 好的哦 麻烦啦
