Is it safe to call something in my RestController from my WebSocketHandler? - spring-boot

Question

I guess this is a bit of a threadsafe question, as I'm not sure how Spring Boot handles beans and web service calls and incoming websocket data.
Is it safe to call controller.doSomething() from McpWebSocketHandler, if I know MCPController.ping() also calls it?
Also, if I have the GameUnitService Autowired in both MCPController and McpWebSocketHandler, will there be any thread contention?

#RestController
public class MCPController implements MqttListener {
Logger log = LoggerFactory.getLogger(MCPController.class);
#Autowired private JdbcTemplate jdbc;
#Autowired private GameUnitService gameUnitService;
#GetMapping("/ping")
public Object ping(HttpServletRequest request) {
String remoteAddr = request.getHeader(FORWARDED) == null ? request.getRemoteAddr() : request.getRemoteAddr() + "/" + request.getHeader(FORWARDED);
log.info("Got ping from {}", remoteAddr);
doSomething();
return new Response(true, ErrorCode.OK, "pong");
}
public String doSomething() {
return gameUnitService.doSomethingWithDatabase();
}
}
public class McpWebSocketHandler extends AbstractWebSocketHandler {
private ApplicationContext appContext;
private GameUnitService gameUnitService;
private MCPController controller;
public McpWebSocketHandler(ApplicationContext appContext,GameUnitService gameUnitService) {
this.appContext = appContext;
this.gameUnitService = gameUnitService;
controller = (MCPController)appContext.getBean("MCPController");
}
#Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
String payload = message.getPayload();
String response = controller.doSomething(); //is this safe?
session.sendMessage(new TextMessage(response));
}
}
