<job id="job">
    <step id="stepA" parent="s1">
        <next on="*" to="stepB" />

public Job job(Tasklet01 tasklet01, Tasklet02 tasklet02, Tasklet03 tasklet03, Tasklet04 tasklet04,) {
    return JobBuilderFactory.get("jobNmae")
                            .start(stepA(tasklet01))
                                .on("FAILED").to(StepC(tasklet03))
                            .from(StepA(tasklet01))
                            .next(StepB(tasklet02))
                                .on("FAILED").to(StepC(tasklet03))
                            .from(StepB(tasklet02))
                                .next(StepD(tasklet04))
                            .end()
                            .build();

• You can control ExitSatus which is used on(“HERE”) using spring batch Context for example :
  I wrote the below code in Tasklet.

chunkContext.getStepContext().getStepExecution().setStatus(BatchStatus.FAILED);"

hope this help you!
