Turns out the CORS is always enabled for WebSocket with SockJS. So, since we cannot predict an URL for the `index.html` therefore we always recommend open it on the same host port as server application - `http://localhost:8080`

WebSockets Sample
|
|
==============
|
|
|
|
This example demonstrates the Standard WebSocket protocol (without any sub-protocols) with Spring Integration Adapters.
|
|
It just sends current time from the server to all connected clients.
|
|
|
|
## Server
|
|
|
|
The server is presented only with a single `org.springframework.integration.samples.websocket.standard.server.Application`
|
|
class, which is based on the Spring Boot AutoConfiguration and Spring Integration Java & Annotation configuration.
|
|
It is a `main` and starts an embedded Tomcat server on the default `8080` port. The WebSocket endpoint is mapped to the `/time` path.
|
|
|
|
The server also can be run from Gradle `gradlew :web-sockets:run`
|
|
|
|
## Java Client
|
|
|
|
The `org.springframework.integration.samples.websocket.standard.client.Application` is a simple Java application,
|
|
which starts an integration flow (`client-context.xml`), connects to the WebSocket server and prints `Message`s to the
|
|
logs, which are received over WebSocket.
|
|
|
|
## Browser Client
|
|
|
|
The `index.html` in the `src/main/resources/static` directory of this project demonstrates a JavaScript `SockJS` client, which connects
|
|
to our server and just prints its messages in the middle of page. It can be reached at http://localhost:8080/index.html.
|
|
|
|
## Test Case
|
|
|
|
The `org.springframework.integration.samples.websocket.standard.ApplicationTests` demonstrates the Spring Boot test
|
|
framework and starts Server & Client to check, that the client receives correct data.
