Spring Boot - not overriding server port property

Question

I've got a Spring Boot project where the server port always gets set to 8080, regardless of the server.port property. All properties except server.port gets overridden correctly. Property configuration bean:

@Bean
public PropertySourcesPlaceholderConfigurer properties() {
    final PropertySourcesPlaceholderConfigurer poc = new PropertySourcesPlaceholderConfigurer();
    poc.setIgnoreResourceNotFound(true);
    poc.setIgnoreUnresolvablePlaceholders(true);

    final List<Resource> list = new ArrayList<Resource>();

    // default (dev) properties
    list.add(new ClassPathResource(PROPERTIES_FILE));

    // override with -Dproperties.location=C:/path/to/properties/ where overriding application.properties resides
    list.add(new FileSystemResource(System.getProperty(EXTERNAL_ARGUMENT_NAME)+PROPERTIES_FILE));

    poc.setLocations(list.toArray(new Resource[]{}));

    return poc;
}

This means my classpath application.properties is the default (dev properties), which get overridden by jvm argument -Dproperties.location=C:\application\config.

The server.port property is not defined in my classpath properties file, so it defaults to 8080 in dev environment. This is fine, but for test I would like to specify the port. My external properties file contains this property:

server.port=10070

Answer 1

If you are using spring actuator in your project, by default it points to 8080, and if you want to change it, then in application.properties mention management.port = 9001

Answer 2

You can also try overriding the port at runtime with -Dserver.port= or --server.port=. Use later when you are running as java -jar. Hope this helps.
