Fedora-20 not booting from Live USB stick

Question

I am trying to execute a method in a separate thread, when the server starts. Please find my main class below:

@SpringBootApplication
@EnableSwagger2
public class Application {

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

    @Bean
    public TaskExecutor taskExecutor() {
        return new SimpleAsyncTaskExecutor(); 
    }
    
    @Bean
    public CommandLineRunner schedulingRunner(TaskExecutor executor) {
        return new CommandLineRunner() {
            public void run(String... args) throws Exception {
                executor.execute(new CsvReader());
            }
        };
    }
}

@Component
public class CsvReader implements Runnable{

    @Value("${file-url}")
    private String appUrl;

    @Override
    public void run() {
        System.out.println("run after Object created: "+ appUrl); // this is coming as null. Not able to read it from application.properties
    }
}

Solution 1

Try using a Fedora-specific tool for creating live USB drives - Fedora Media Writer (Windows/Mac/Linux). Fedora Media Writer (formerly Fedora Live USB Creator) is a free and open source tool for easily installing live operating systems onto USB flash drives.

Features

• Cross-platform (available for Windows, Mac and Linux)
• There is no need to deal with formatting or partitioning your USB flash drive.
• Automatically detects all removable devices
• Supports automatically downloading various Fedora releases
• Persistent storage creation, to save all documents created and modifications made to the system
• Checksum verification
• Not limited to Fedora releases, supports custom images

Solution 2

checkout this link https://fedoraproject.org/wiki/How_to_create_and_use_Live_USB

follow the dd command it worked for me

To write the ISO file directly to the disk, run:

su -c "dd if=/Users/me/Downloads/Fedora-17-x86_64-DVD.iso of=/dev/sdX bs=8M"

Or, if you are running an Ubuntu-based distribution

sudo dd if=/Users/me/Downloads/Fedora-17-x86_64-DVD.iso of=/dev/sdX bs=8M

I had a similar problem with OpenSuse - using the custom OS tool worked a treat, and was way-easier than the hack-around I was trying.

What does this do? What is /dev/sdX? Why is this better than the current method? Just giving a command hamstrings your answer. More details will turn this from a cryptic string into a potentially awesome answer.

Autowiring of beans would fail, because container is not injecting the dependency

[linhx]

it's not about you executing CsvReader in a separate thread. it because you create CsvReader by new operator, the object is not manage by Spring container. You could keep your old code and use @Autowired private CsvReader csvReader; in the Application class, and Spring will inject the bean it manages. then use executor.execute(csvReader);
