我尝试使用websocket。作为我使用Glassfish的服务器,工作正常,但我有websocket的问题。
当我在控制台中使用javascript运行html时出现错误404

int sentMessages = 0;
while(sentMessages < 3){
Thread.sleep(5000);
session.getBasicRemote().

Gradle构建没有错误。当我在qazxsw poi(vagrant虚拟机)中运行应用程序时
抛出错误:
与'ws:// localhost:8080 / web / websocket'的WebSocket连接失败:WebSocket握手期间出错:意外响应代码:404
在glassfish中,在Context Root:web中添加应用程序
怎么了 ?你能帮助我吗?请。谢谢 :)
答案
您应该将ServerEndPoint设置为一个值。 ServerEndPoint(value =“/ websocket”)
另一答案
对于它添加以下选项后工作:
http://192.168.37.10:8080/web/page.html
或者在web.xml中:
atmosphere.addInitParameter(ApplicationConfig.PROPERTY_NATIVE_COMETSUPPORT, "true");
atmosphere.addInitParameter(ApplicationConfig.WEBSOCKET_SUPPRESS_JSR356, "true");
以上是关于Glassfish websocket无法正常工作的主要内容,如果未能解决你的问题,请参考以下文章
无法通过 tomcat 中的 websocket 发送二进制消息,但可以在 glassfish 中使用。使用 IllegalArgumentException 在 tomcat 中失败
