在SpringBoot项目中使用AWT的Toolkit.getDefaultToolkit().getScreenSize()时出现Exception in thread “JavaFX Application Thread” java.awt.HeadlessException错误

可以修改启动类为：

@SpringBootApplication
public class RmToolApplication implements CommandLineRunner {

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

	@Override
	public void run(String... args) throws Exception {
		Application.launch(MainApp.class, args);
	}

}
