you can also write like below :

    @RequestMapping(value = "/updateStatusAndRestart/{jobId}/{stepId}", method = GET)
    public ResponseEntity updateBatchStatus(@PathVariable("jobId") Long jobExecutionId ,@PathVariable("stepId")Long stepExecutionId )throws Exception {

       StepExecution stepExecution =  jobExplorer.getStepExecution(jobExecutionId,stepExecutionId);
            stepExecution.setEndTime(new Date(System.currentTimeMillis()));
            stepExecution.setStatus(BatchStatus.FAILED);
            stepExecution.setExitStatus(ExitStatus.FAILED);
        jobRepository.update(stepExecution);

       JobExecution jobExecution =  stepExecution.getJobExecution();
            jobExecution.setEndTime(new Date(System.currentTimeMillis()));
            jobExecution.setStatus(BatchStatus.FAILED);
            jobExecution.setExitStatus(ExitStatus.FAILED);
        jobRepository.update(jobExecution);
        jobOperator.restart(execution.getId());
        
        return new ResponseEntity("
 Batch Status Updated !! 
", HttpStatus.OK);
    }

Here i have used restApi endpoint to pass the jobExecutionId and stepExecutionId and setting the status of both job_execution and step_execution to FAIL. then restart using batch operator.
