I have a spring boot application (using embedded tomcat 7), and I've set server.port = 0
in my application.properties
so I can have a random port. After the server is booted up and running on a port, I need to be able to get the port that that was chosen.
I cannot use @Value("$server.port")
because it's zero. This is a seemingly simple piece of information, so why can't I access it from my java code? How can I access it?
Is it also possible to access the management port in a similar way, e.g.:
@SpringBootTest(classes = {Application.class}, webEnvironment = WebEnvironment.RANDOM_PORT)
public class MyTest {
@LocalServerPort
int randomServerPort;
@LocalManagementPort
int randomManagementPort;
