My CODE :::
@SpringBootApplication
public class BatchDemo {
public static void main(String args[])
{
SpringApplication.run(BatchDemo.class);
}
}
I was able to resolve it by adding exclude = BatchAutoConfiguration.class. But I would like to find the actual cause and fix it.
I am not passing any commandline arguments and this exception doesn’t occur all the time.

The stack trace indicates that the java.lang.IndexOutOfBoundsException is occurring when trying to retrieve job parameters while executing the CommandLineRunner for Spring Batch. The root cause seems to be that the JobParametersBuilder is not able to retrieve job parameters from an empty list.
To resolve this issue, you can check if there are job parameters available before trying to retrieve them. You can use the JobParameters to pass parameters to your job, and it’s essential to ensure that the parameters are available before execution.
Here’s an updated version of your main class that checks for job parameters:
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.JobParametersBuilder;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.batch.BatchAutoConfiguration;@SpringBootApplication(exclude = BatchAutoConfiguration.class)
public class BatchDemo {
public static void main(String args[]) {
// Check if job parameters are available before running the application
JobParameters jobParameters = new JobParametersBuilder().toJobParameters();
if (jobParameters.getParameters().isEmpty()) {
SpringApplication.run(BatchDemo.class);
}
}
}
By using JobParametersBuilder().toJobParameters(), we create an empty set of job parameters, and then we check if the parameters map is empty. If it is empty, we do not execute the SpringApplication.run(). This will prevent the IndexOutOfBoundsException from occurring when there are no job parameters available.
Please note that this solution assumes that there is a specific scenario in your application where you expect job parameters to be available. If the absence of job parameters is expected in other scenarios, you can further customize the condition accordingly.
Remember to handle job parameters appropriately when running your Spring Batch job to pass any required parameters during execution.
