I want to have just one TCP socket that connects to another program. Every new call to my rest endpoint writes to my TCP socket. If I write a class with my TCP socket and inject it into my Controller class, will it be thread safe? or do I have to synchronize them using the synchronize keyword?
@Component
public class ViconetBuffer
private Socket socket;
private boolean connectToViconSocket()
try
socket = new Socket(DeviceAddressUtil.socketIp,DeviceAddressUtil.port);
return true;
catch (Exception ex)
ex.printStackTrace();
return false;
public void sendDataToViconSocket(String message)
try
if (!socket.isConnected())
connectToViconSocket();
else socket.getOutputStream().write(message.getBytes());
catch (Exception ex)
ex.printStackTrace();

No, that's your job. Spring/CDI/EJB can not know how you want the several threads to coordinate their use of the Socket.

So should I not inject the class and make the methods synchronized and the socket static?
