java.awt.HeadlessException: null的异常处理方法解决方法

实现思路:
    在启动配置中VM options添加：-Djava.awt.headless=false
  

SpringBoot程序运行时，如何设置headless参数

@SpringBootApplication
@EnableScheduling
public class Application {
    public static void main(String[] args) throws Exception {
        SpringApplicationBuilder builder = new SpringApplicationBuilder(Application.class);
        builder.headless(false).run(args);
    }
}
