[英]communication between two JAVA web applications using Websockets
I have a java web application (Servlet and JSP based) running on local machine with chat facility using HTML5 and Java WebSocket api. 我有一个Java Web应用程序(基于Servlet和JSP)在本地计算机上运行,具有使用HTML5和Java WebSocket api的聊天功能。 One can chat with other user logged in on same application (using two different browsers).
一个人可以与登录同一应用程序的其他用户聊天(使用两个不同的浏览器)。
I have created a replica of same project (web application) and changed the required configuration to run it as a different web-app. 我已经创建了相同项目(Web应用程序)的副本,并更改了所需的配置以将其作为其他Web应用程序运行。 What I want is that a user logged-in on ,say web-app1, can chat with user logged-in on web-app2.
我要的是一个登录用户(例如web-app1)可以与登录到web-app2的用户聊天。
Here are the code snippet of ServerEndpoint annotation and JavaScript code to connect to websocket end point 这是ServerEndpoint批注的代码段和连接到Websocket端点的JavaScript代码
@ServerEndpoint(value = "/chat/{sessionId}",
encoders = ChatMessageCodec.class,
decoders = ChatMessageCodec.class,
configurator = ChatEndpoint.EndpointConfigurator.class)
@WebListener
public class ChatEndpoint implements HttpSessionListener
{
.....
....................... .......................
var server;
try {
server = new WebSocket('ws://' + window.location.host +'<c:url
value="/chat/${chatSessionId}" />');
server.binaryType = 'arraybuffer';
}
catch(error) {
modalErrorBody.text(error);
modalError.modal('show');
return;
}
I am new to java web development and this web app is part of the project from book I am following :| 我是Java Web开发的新手,此Web应用程序是我关注的书中的项目的一部分:|
I think you'd be better off using message queues for communications between two or more JVMs. 我认为最好使用消息队列在两个或多个JVM之间进行通信。 WebSocket is not an ideal solution for this kind of tasks
WebSocket并非此类任务的理想解决方案
