Spring batch retry mechanism for reader failure

Question

I have one spring batch job which will run daily once. I had implemented reader, processor and writer. Suppose if any exception happens while running reader task, then entire job will fail. I want to rerun same day for that failure jobs after 5 mins or immediately. Kindly let me know how i can implement in spring batch or provide me any sample code or website which have information.

Answer 1

Take a look at Spring Retry. It started as part of Spring Batch but as of version 2.2.0 it has spined-off to a standalone project (and dependency).

Being able to use it declaratively is particularly nice:

import org.springframework.retry.annotation.Backoff;
import org.springframework.retry.annotation.Retryable;

public interface MyExampleService {

@Retryable(maxAttempts = 3, backoff = @Backoff(delay = 2000))
String callService() throws Exception;
}
