II. Overview

1. Introduction

For default, when running a restartable Batch Job, a step is executed if it was FAILED in a previous execution and do NOT be invoked if it was COMPLETED. Spring Batch also supports some specific configuration for Steps when restart a Job. - Setting a StartLimit: help control the number of times that a Step may be started.

<step id="step3">
    <tasklet start-limit="${limitstart}" ref="taskletStep3"/>
</step>

• allow-start-if-complete: in case restartable Job, steps with the configuration allow-start-if-complete=“true” are always be invoked to run.

<step id="step3">
    <tasklet start-limit="${limitstart}" ref="taskletStep3"/>
</step>

2. Project Structure

In the tutorial, a Job will be created with 3 step: step1->step2->step3 - Step1 with no additional configuration - Step2 is configured with allow-start-if-complete="true" - Step3 is configured with start-limit="${limitstart}"
