Spring Batch restart from last exception - spring-batch

Question

I would like to restart a batch after it was terminated
I stop a batch when a particular exception throws :
public class IntegrationItemProcessorExceptionHandler implements ExceptionHandler {
private static final Logger LOG = LoggerFactory.getLogger(IntegrationItemProcessorExceptionHandler.class);
#Override
public void handleException(RepeatContext context, Throwable throwable) throws Throwable {
LOG.error("handleException", throwable);
if (throwable instanceof CustomResponseException) {
context.setTerminateOnly();
}
}
}
The input is a json I read with a FlatFileItemReader
#Bean
public ItemReader<UserDto> reader() {
FlatFileItemReader<UserDto> reader = new FlatFileItemReader<MerchantDTO>();
reader.setResource(new ClassPathResource("user.json"));
reader.setRecordSeparatorPolicy(new CustomJsonRecordSeparatorPolicy());
reader.setLineMapper(new CustomLineMapper());
return reader;
}
If CustomResponseException is throws by the ItemProcessor, I stop the batch.
After, I would like to restart the batch, but at the same line I stoped it.
What I need to to to have this behavor ??
And my job config :
#Bean
public Job importUserJob(JobBuilderFactory jobs, Step s1) {
return jobs.get("integrationJob")
.incrementer(new RunIdIncrementer())
.flow(s1)
.end()
.build();
}
#Bean
public Step step1(StepBuilderFactory stepBuilderFactory) {
return stepBuilderFactory.get("step1")
.<UserDTO, User>chunk(10)
.reader(reader())
.processor(processor())
.writer(writer())
.listener(new IntegrationItemProcessorListener())
.exceptionHandler(new IntegrationItemProcessorExceptionHandler())
.build();
}
