Springboot app gives error after starting

Question

I wrote a springboot application but it gives error before run method execution.I observed with debug it enters main method but after that it gives error immediately.I checked pom.xml file but I did not find any problem with dependencies.

Error is : org.springframework.boot.context.config.ConfigFileApplicationListener.supportsSourceType(Ljava/lang/Class;)Z

Do you have any idea?

My app class is :

@Configuration
@SpringBootApplication
public class ProcessesApplication implements CommandLineRunner {    

private static Logger logger = LoggerFactory.getLogger(ProcessesApplication.class);

@Autowired
private BatchManager batchManager;



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

}

@Override
public void run(String... args) throws Exception {
    Integer threadCount = 5;        
    try {        
        if (args.length > 1 && args[1] != null && !args[1].trim().isEmpty()) {
            try {
                threadCount = Integer.valueOf(args[1].trim());
            } catch (Exception e) {
               e.getStackTrace(e));
            }
        }
       
        this.batchManager.setThreadCount(threadCount);
        this.batchManager.setProcessName("Process");
        this.batchManager.start();
    } catch (Exception e) {
        e.getStackTrace(e);
    }
}

}

My pom.xml is

Answer 1

I would suggest seperating the class with main() function from the other class.

Basically create a class that has only the main() function inside and another class for the CommandLineRunner.

Example:

@SpringBootApplication
@EnableAsync
public class SpringApp{

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

And a seperate Class for the Runner:

@Component
public class ARunner implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments args) throws Exception
    {
        // Your code...
    }
}

Answer 2

Remove @Configuration annotation
