Fixes spring-projects/spring-integration-samples#198 The `SocketUtils.findAvailableServerSocket()` isn't reliable for port selection and its `socket.close()` may cause a port selection by some other process. Use OS-selected port for SshdServer in SFTP sample Revert unexpected refactoring after renaming properties Upgrade to SSHD-1.4, FTP Server 1.1, fix tests and Boot 2.0 compatibility
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 Messages 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.
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.
