我正在尝试使用 grails 创建聊天应用程序。我正在使用 grails 3.0.9 和 tomcat-8.0.28
抱歉重复
我读了这个问题和这个......但这并不能解决我的问题......
我已经将 javax.websocket-api 更改为像这样提供：
provided 'javax.websocket:javax.websocket-api:1.0'
但我仍然收到此错误：
Firefox: Firefox 无法在http://103.56.148.50/chat/chatEndPoint/C001D939F2564251C86E646B9127495D与服务器建立连接"
Chrome：WebSocket 握手期间出错：意外响应代码：404
你可以看到这个网站...
这是我的代码
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);
}
}
这是在javascript中
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");
}
这是我在 build.gradle 中的依赖项

==================================================== ==================
我试图运行：grails prod run-app
我的 websocket 变得不工作了......
但是如果我运行 grails run-app 它就可以了
那是因为ServerEndPointDemo.groovy我把在/src/main/groovy/com.akiong/ServerEndPointDemo.groovy ？
