Fails in spring boot

[BenjaminJamesNexia]

I am trying to use SikuliiX1 from a Spring boot application, maven

    <dependency>
        <groupId>com.sikulix</groupId>
        <artifactId>sikulixapi</artifactId>
        <version>1.1.4-20191010.160947-268</version>
    </dependency>    

It runs fine if I test just the operation of the sikulli (ie with a main method in the class so it just runs the sikuli code), but when I run the same code within the Spring application (calling the same methods but within the Spring application) they fail with a null exception. This comes from (when I run the debugs through) a failed attempt to create new RepeatableFind. I recall seeing RaiMan comment on this being due to some reason in another post but wondering if this is something I can fix as it would be great to use Sikuli directly rather than via calling a separate jar file through a process.....

The previous comment I referred to:

RaiMan commented on this issue 2 years ago.

Apparently, the class-reference-imagePath does not work in a spring application.ImagePath.add(new ClassPathResource("images").getURL()); Is ClassPathResource Spring specific or Java standard?

I guess your problem is that SikuliX thinks it's in headless mode when executed from a Spring Boot application. Hence it doesn't initialize the screens.

You can set the java.awt.headless property to false.

Either from code using System.setProperty("java.awt.headless", "false") or (preferably) by a VM argument upon application start -Djava.awt.headless=false.

If this solution doesn't work for you it would be nice if you could provide a full stacktrace.

Awesome, thanks very much, adding this to the POM.xml file fixed the problem:

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <jvmArguments>              
                    -Xms8g
                    -Xmx16g
                    -Djava.awt.headless=false
                </jvmArguments>
            </configuration>                
        </plugin>

Glad to help.

Another option would be to change your Application class from

public class Application {
  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

to

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