    从类复制的说明: SimpleStepHandler
    Check mandatory properties (jobRepository).
    指定者:
    afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean
    覆盖:
    afterPropertiesSet 在类中 SimpleStepHandler
    抛出:
    java.lang.Exception

  - shouldStart
```

    shouldStart 在类中 SimpleStepHandler
    参数:
    lastStepExecution - the last step execution
    jobExecution - instance of JobExecution
    step - instance of Step

    true if step should start, false if it should not.
    抛出:
    StartLimitExceededException - if the start limit has been exceeded for this step
    JobRestartException - if the job is in an inconsistent state from an earlier failure
