Run Spring Boot Headless

Question

I have a spring boot application and I would like to run it headless. When I run from the terminal this is the command I'm using:

java -jar myapp.jar --spring.main.headless=true

Is this correct? Any help is well appreciated.

Answer 1

I've faced with same problem and solved it using SpringApplicationBuilder class. You should set headless false (which is true by default). See javadoc.

My main method looks like this:

  public static void main(String[] args) {
    SpringApplicationBuilder builder = new SpringApplicationBuilder(App.class);
    builder.headless(false).run(args);
  }

Answer 2

The spring.main.* properties are injected into the SpringApplication. It doesn't know anything about heads or headlessness. Maybe you need java -Djava.awt.headless=true ...?
