grailsでチャットアプリを作ろうとしています。私はgrails 3.0.9とtomcat-8.0.28を使用しています
重複して申し訳ありません
私はこの質問とこれを読みました...しかし、それは私の問題を解決しません..
私はすでに javax.websocket-api を次のように提供されたものに変更しています:
provided 'javax.websocket:javax.websocket-api:1.0'
しかし、私はまだこのエラーが発生します:
Firefox: Firefox はhttp://103.56.148.50/chat/chatEndPoint/C001D939F2564251C86E646B9127495Dでサーバーへの接続を確立できません」
Chrome: WebSocket ハンドシェイク中のエラー: 予期しない応答コード: 404
あなたはこのサイトを見ることができます...
これは私のコードです
package com.akiong
import grails.util.Environment
import grails.util.Holders
import javax.servlet.ServletContext
import javax.servlet.ServletContextEvent
import javax.servlet.ServletContextListener
import javax.servlet.annotation.WebListener
import javax.websocket.EndpointConfig
import javax.websocket.OnClose
import javax.websocket.OnError
import javax.websocket.OnMessage
import javax.websocket.OnOpen
import javax.websocket.Session
import javax.websocket.server.PathParam
import javax.websocket.server.ServerContainer
import javax.websocket.server.ServerEndpoint
import com.akiong.services.ChatService
import javax.websocket.EncodeException
//import org.codehaus.groovy.grails.commons.ApplicationHolder as AH
import javax.servlet.annotation.WebListener
import java.util.concurrent.CopyOnWriteArraySet
@WebListener
@ServerEndpoint(value="/chat/chatEndPoint/{username}")
public class ServerEndPointDemo implements ServletContextListener {
private static HashMap<String, String> usersMap = new HashMap<String, String>();
private static final Set<ServerEndPointDemo> connections = new CopyOnWriteArraySet<>();
private String username
private Session session
@OnOpen
public void handleOpen(Session session,@PathParam("username") String user){
System.out.println("-------------------------------------");
System.out.println(session.getId() + " has opened a connection");
println "user = "+user
connections.add(this);
this.username = user
this.session = session
}
@OnClose
public void handleClose(Session session){
System.out.println("Session " +session.getId()+" has ended");
}
@OnMessage
public String handleMessage(String message,Session session){
println "message = "+message
println "session= "+session.getId()
}
@OnError
public void handleError(Throwable t){
connections.remove(this);
println "username = "+username
removeUserInMap(session.getId(), username);
}
}
これはJavaScriptで
var wsUri = "ws://103.56.148.50/chat/chatEndPoint/"+room;
var webSocket = new WebSocket(wsUri);
webSocket.onopen = function(message) {OnOpen(message);};
webSocket.onclose = function(message) {OnClose(message);};
webSocket.onerror = function(message) {OnError(message);};
webSocket.onmessage = function(message) {OnMessage(message);};
function OnOpen(message){
console.log("Open Socket");
}
function OnClose(message){
console.log("Close = "+message);
webSocket.close();
}
function OnError(message){
console.log("ERROR = "+message);
}
function OnMessage(message){
webSocket.send("success");
}
これはbuild.gradleの私の依存関係です

================================================== =================
実行しようとしました: grails prod run-app
私のウェブソケットが機能しなくなりました...
しかし、grails run-app を実行すると動作します
それはServerEndPointDemo.groovy私が入れたから/src/main/groovy/com.akiong/ServerEndPointDemo.groovy ですか？
