WebSocket之获取HttpSession
由于WebSocket与Http协议的不同,故在使用常用的HttpSession方面就存在了一些问题。通过google翻阅到了在onOpen方法下使用HttpSession的方法。
新建一个GetHttpSessionConfigurator类并继承Configurator类
package per.zww.web; import javax.servlet.http.HttpSession;
import javax.websocket.HandshakeResponse;
import javax.websocket.server.HandshakeRequest;
import javax.websocket.server.ServerEndpointConfig;
import javax.websocket.server.ServerEndpointConfig.Configurator;
/*
* 获取HttpSession
*
*/ public class GetHttpSessionConfigurator extends Configurator { @Override
public void modifyHandshake(ServerEndpointConfig sec,
HandshakeRequest request, HandshakeResponse response) {
// TODO Auto-generated method stub
HttpSession httpSession=(HttpSession) request.getHttpSession();
sec.getUserProperties().put(HttpSession.class.getName(),httpSession);
} }
然后在@ServerEndpoint注解里面添加configurator属性
@ServerEndpoint(value="/socketTest",configurator=GetHttpSessionConfigurator.class)
在onOpen方法里加入参数EndpointConfig config即可获取HttpSession
@OnOpen
public void onOpen(Session session,EndpointConfig config) {
HttpSession httpSession= (HttpSession) config.getUserProperties().get(HttpSession.class.getName());
System.out.println( httpSession.getAttribute("name"));
sessionMap.put(session.getId(), session);
}
