用什么启动项目的???

走的是nutz-web吗??

用netty 8 启动的...

启动代码在这里

https://github.com/NLPchina/Jcoder/blob/master/src/main/java/Bootstrap.java

// web server

providedCompile 'org.eclipse.jetty:jetty-webapp:9.2.2.v20140723'
providedCompile 'org.eclipse.jetty:jetty-jsp:9.2.2.v20140723'
providedCompile 'org.eclipse.jetty:jetty-continuation:9.2.2.v20140723'
providedCompile 'org.eclipse.jetty.websocket:websocket-server:9.2.2.v20140723'

这是完整的依赖

https://github.com/NLPchina/Jcoder/blob/master/build.gradle

额 是jetty9 .......

报告兽总再step种加入

WebAppContext.Context ct = (WebAppContext.Context) nc.getServletContext() ;
		WebAppContext webAppContext = (WebAppContext) ct.getContextHandler() ;
		ServerContainer configureContext = WebSocketServerContainerInitializer.configureContext(webAppContext) ;
		Arrays.stream(nc.getIoc().getNames()).forEach(name ->{
			Object object = nc.getIoc().get(Object.class, name) ;
			if(object.getClass().getAnnotation(ServerEndpoint.class)!=null){
				try {
					configureContext.addEndpoint(object.getClass());
					LOG.info("add "+object.getClass()+" in websocket container");
				} catch (Exception e) {
					LOG.error("add "+object.getClass()+" in websocket container fail!!",e);
				}
			}
		});

就可以了。。。我这个ioc遍历的是不是有点龌龊求指点。。
