public class JobStep
extends AbstractStep
```
A Step that delegates to a Job to do its work. This is a great tool for managing dependencies between jobs, and also to modularise complex step logic into something that is testable in isolation. The job is executed with parameters that can be extracted from the step execution, hence this step can also be usefully used as the worker in a parallel or partitioned execution.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`afterPropertiesSet()`
`protected void`	`doExecute(StepExecution stepExecution)`	Execute the job provided by delegating to the `JobLauncher` to prevent duplicate executions.
`void`	`setJob(Job job)`	The `Job` to delegate to in this step.
`void`	`setJobLauncher(JobLauncher jobLauncher)`	A `JobLauncher` is required to be able to run the enclosed `Job`.
`void`	`setJobParametersExtractor(JobParametersExtractor jobParametersExtractor)`	The `JobParametersExtractor` is used to extract `JobParametersExtractor` from the `StepExecution` to run the `Job`.

  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws java.lang.Exception
```
    Specified by:
    afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean
    Overrides:
    afterPropertiesSet in class AbstractStep
    Throws:
    java.lang.Exception
  - setJob
```
public void setJob(Job job)
```
    The Job to delegate to in this step.
    Parameters:
    job - a Job
  - setJobLauncher
```
public void setJobLauncher(JobLauncher jobLauncher)
```
    A JobLauncher is required to be able to run the enclosed Job.
    Parameters:
    jobLauncher - the JobLauncher to set
  - setJobParametersExtractor
```
public void setJobParametersExtractor(JobParametersExtractor jobParametersExtractor)
```
    The JobParametersExtractor is used to extract JobParametersExtractor from the StepExecution to run the Job. By default an instance will be provided that simply copies the JobParameters from the parent job.
    Parameters:
    jobParametersExtractor - the JobParametersExtractor to set
  - doExecute
```
protected void doExecute(StepExecution stepExecution)
                  throws java.lang.Exception
```
    Execute the job provided by delegating to the JobLauncher to prevent duplicate executions. The job parameters will be generated by the JobParametersExtractor provided (if any), otherwise empty. On a restart, the job parameters will be the same as the last (failed) execution.
    Specified by:
    doExecute in class AbstractStep
    Parameters:
    stepExecution - the current step context
    Throws:
    java.lang.Exception - checked exception thrown by implementation
