server.port should not be set to -1 if the test does not start an embedded web server #16998
Description
when i use spring-boot for no-web application, in the spring-boot-test ,"server.port" was be override by org.springframework.boot.test.context.SpringBootContextLoader.getInlinedProperties()
properties.add("server.port=-1") . therefore on my unit test, i cannot start server.
application.properties:
server.port=12345
server.name=myserver`
MyServer.java:
@Component
public class MyServer implements Closeable {
@Value("${server.port}")
private int serverPort;
@Value("${server.name}")
private String serverName;
private ServerSocket serverSocket;
@PostConstruct
public void init() {
System.out.println("server.port:" + serverPort);
System.out.println("server.name:" + serverName);
// start my server on port "server.port"
....
}
}SpringBootDemoApplication.java:
@SpringBootApplication
public class SpringBootDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
}SpringBootDemoApplicationTest.java:
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringBootDemoApplicationTest {
@Resource
private MyServer myServer;
@After
