  抛出:

  java.lang.Exception

  InitializingBean.afterPropertiesSet()

• getJobRepository

  protected JobRepository getJobRepository()

  返回:

  the used jobRepository

• setJobRepository

  public void setJobRepository​(JobRepository jobRepository)

  参数:

  jobRepository - the jobRepository to set

• setExecutionContext

  public void setExecutionContext​(ExecutionContext executionContext)

  A context containing values to be added to the step execution before it is handled.

  参数:

  executionContext - the execution context to set

• handleStep

  public StepExecution handleStep​(Step step,
                                  JobExecution execution)
                           throws JobInterruptedException,
                                  JobRestartException,
                                  StartLimitExceededException

  从接口复制的说明: StepHandler
  Handle a step and return the execution for it. Does not save the JobExecution, but should manage the persistence of the StepExecution if required (e.g. at least it needs to be added to a repository before the step can be executed).

  指定者:

  handleStep 在接口中 StepHandler

  参数:

  step - a Step

  execution - a JobExecution

  返回:

  an execution of the step

  抛出:

  JobInterruptedException - if there is an interruption

  JobRestartException - if there is a problem restarting a failed step

  StartLimitExceededException - if the step exceeds its start limit

• shouldStart

  protected boolean shouldStart​(StepExecution lastStepExecution,
                                JobExecution jobExecution,
                                Step step)
                         throws JobRestartException,
                                StartLimitExceededException

  Given a step and configuration, return true if the step should start, false if it should not, and throw an exception if the job should finish.

  参数:

  lastStepExecution - the last step execution

  jobExecution - the JobExecution instance to be evaluated.

  step - the Step instance to be evaluated.

  返回:

  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
