'ws://localhost:8080/websocket' failed: Error during WebSocket handshake: Unexpected response code: 500
环境是java8，tomcat8.8.6， web-inf/libs目录下没有和tomcat 冲突的jar包；
使用了nutz-plugin-websocket的插件，
然后再pom.xml文件中引用了
但是却报了以上的错误，
<dependency>
<groupId>javax.websocket</groupId>
<artifactId>javax.websocket-api</artifactId>
<version>1.1</version>
<scope>provided</scope>
</dependency>
后台跟这个有关的报了一个，其他的没有
[DEBUG] 2017-06-08 23:02:06,348 org.nutz.mvc.impl.UrlMappingImpl.get(UrlMappingImpl.java:110) - Search mapping for [GET] path=/websocket : NOT Action match
浏览器端报的错
WebSocket connection to 'ws://localhost:8080/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404
处理的类只有两个一个handler，一个endpoint；
@IocBean
@ServerEndpoint(value = "/webscoket", configurator=NutWsConfigurator.class)
public class ChatServer extends AbstractWsEndpoint {
@Inject
Dao dao;
public WsHandler createHandler(Session session, EndpointConfig config) {
ChatHandler handler = new ChatHandler(roomPrefix, dao,this.sessions);
handler.setRoomProvider(roomProvider);
handler.setSession(session);
return handler;
}
}
Error during WebSocket handshake: Unexpected response code: 500
浏览器看的错误，这个是在建立连接时出的错，应该是通讯层的错误，跟应用还没有关系
自己写了个简单的websocket却能正常连接
用nutz的websocket的插件却不行
/**
*
*/
@ServerEndpoint(value = "/websocket1")
public class Testws {
@OnOpen
public void onOpen(Session session, EndpointConfig config) {
System.out.print(1);
}
@OnClose
public void onClose(Session session, CloseReason closeReason) {
}

跟ioc没有挂系，ioc都能正常的取到，
sec.getUserProperties().put("HttpSession",request.getHttpSession());
就是这段代码的问题，如果去掉这段，或者改掉这段这样写
sec.getUserProperties().put("HttpSession",1);
都不会报500错误，websocket都能正常连接，就是不能调用request.getHttpSession()
这个会返回一个null，这个插件还有什么限制要求没有；
public void modifyHandshake(ServerEndpointConfig sec,
HandshakeRequest request,
HandshakeResponse response) {
super.modifyHandshake(sec, request, response);
HttpSession session = request.getHttpSession();
if (session != null)
sec.getUserProperties().put("HttpSession", );
}
