Spring-boot: Fails to start when using @SpringBootApplication with SpringApplicationBuilder.sources

Created on 26 Feb 2018 · 6Comments · Source: spring-projects/spring-boot

use @SpringBootApplication with SpringApplicationBuilder，my app starts failed

// main method
new SpringApplicationBuilder()
                .sources(ParentConfig.class)
                .child(Child1Config.class)
                .sibling(Child2Config.class)
                .banner(new AppBanner())
                .logStartupInfo(false)
                .run(args);

// ParentConfig
@SpringBootApplication
@PropertySource("classpath:/parent.properties")
public class ParentConfig {
}

// Child1Config 
@SpringBootApplication
@PropertySource("classpath:/child1.properties")
public class Child1Config {

}

// Child2Config 
@SpringBootApplication
@PropertySource("classpath:/child2.properties")
public class Child2Config {

}

the error log as follow:

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

the version of springboot is "2.0.0.RC2" or "2.0.0.BUILD-SNAPSHOT"

but if i change the version to "1.5.10.RELEASE", it work fine.
Another solutation is change the @SpringBootApplication to @Configuration in ParentConfig.java.

I don't know why, can anyone tell me? Thank you very much!!!!

I have also faced the same issue, to overcome this issue you can kill the PID using following commands.

C:\Users\Admin> netstat -ano | findstr :8080

It will show as below:

  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       6956
  TCP    [::]:8080              [::]:0                 LISTENING       6956

Then run the below command to kill the PID

C:\Users\Admin>taskkill /PID 6956 /F
SUCCESS: The process with PID 6956 has been terminated.

Now you can re run the Spring application smoothly. Thank you!!

You have started multiple SpringApplications with a web environment. Two or more of them are configured to use the same port so the second fails with a port clash. Also, your use of PropertySource is not recommended in a Spring Boot app as the configuration it contains may be available too late.

In the future please ask this sort of question on Gitter or Stack Overflow. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements.

@wilkinsona Thank you for answering me!
I'll do it as you say.

I just want to know why the above code can run normally in version 1.x, and there will be a port conflict error in version 2.x. What's the reason for the change in version 2.

Thanks again.

There's been no change in Spring Boot 2 in this area. The same arrangement will fail with 1.5:

@wilkinsona thank you，i will do it

I have also faced the same issue, to overcome this issue you can kill the PID using following commands.

C:\Users\Admin> netstat -ano | findstr :8080

It will show as below:

  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       6956
  TCP    [::]:8080              [::]:0                 LISTENING       6956

Then run the below command to kill the PID

C:\Users\Admin>taskkill /PID 6956 /F
SUCCESS: The process with PID 6956 has been terminated.

Now you can re run the Spring application smoothly. Thank you!!

Run the command with the port used : example : lsof -i : 8080(Port number)

Now kill the process. command -: kill -9 (example : kill -9 8080).
