类 AbstractStep

构造器详细资料

• AbstractStep

  public AbstractStep()

  Default constructor.

• AbstractStep

  public AbstractStep​(java.lang.String name)

  Convenient constructor for setting only the name property.

  参数:

  name - Name of the step

方法详细资料

• afterPropertiesSet

  public void afterPropertiesSet()
                          throws java.lang.Exception

  指定者:

  afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean

  抛出:

  java.lang.Exception

• getName

  public java.lang.String getName()

  指定者:

  getName 在接口中 Step

  返回:

  the name of this step.

• setName

  public void setName​(java.lang.String name)

  Set the name property. Always overrides the default value if this object is a Spring bean.

  参数:

  name - the name of the Step.

  setBeanName(java.lang.String)

• setBeanName

  public void setBeanName​(java.lang.String name)

  Set the name property if it is not already set. Because of the order of the callbacks in a Spring container the name property will be set first if it is present. Care is needed with bean definition inheritance - if a parent bean has a name, then its children need an explicit name as well, otherwise they will not be unique.

  指定者:

  setBeanName 在接口中 org.springframework.beans.factory.BeanNameAware

  另请参阅:

  BeanNameAware.setBeanName(java.lang.String)

• getStartLimit

  public int getStartLimit()

  指定者:

  getStartLimit 在接口中 Step

  返回:

  the number of times a job can be started with the same identifier.

• setStartLimit

  public void setStartLimit​(int startLimit)

  Public setter for the startLimit.

  参数:

  startLimit - the startLimit to set

• isAllowStartIfComplete

  public boolean isAllowStartIfComplete()

  指定者:

  isAllowStartIfComplete 在接口中 Step

  返回:

  true if a step that is already marked as complete can be started again.

• setAllowStartIfComplete

  public void setAllowStartIfComplete​(boolean allowStartIfComplete)

  Public setter for flag that determines whether the step should start again if it is already complete. Defaults to false.

  参数:

  allowStartIfComplete - the value of the flag to set

• doExecute

  protected abstract void doExecute​(StepExecution stepExecution)
                             throws java.lang.Exception

  Extension point for subclasses to execute business logic. Subclasses should set the ExitStatus on the StepExecution before returning.

  参数:

  stepExecution - the current step context

  抛出:

  java.lang.Exception - checked exception thrown by implementation

• open

  protected void open​(ExecutionContext ctx)
               throws java.lang.Exception

  Extension point for subclasses to provide callbacks to their collaborators at the beginning of a step, to open or acquire resources. Does nothing by default.

  参数:

  ctx - the ExecutionContext to use

  抛出:

  java.lang.Exception - checked exception thrown by implementation

• close

  protected void close​(ExecutionContext ctx)
                throws java.lang.Exception

  Extension point for subclasses to provide callbacks to their collaborators at the end of a step (right at the end of the finally block), to close or release resources. Does nothing by default.

  参数:

  ctx - the ExecutionContext to use

  抛出:

  java.lang.Exception - checked exception thrown by implementation

• execute

  public final void execute​(StepExecution stepExecution)
                     throws JobInterruptedException,
                            UnexpectedJobExecutionException

  Template method for step execution logic - calls abstract methods for resource initialization ( open(ExecutionContext)), execution logic (doExecute(StepExecution)) and resource closing ( close(ExecutionContext)).

  指定者:

  execute 在接口中 Step

  参数:

  stepExecution - an entity representing the step to be executed

  抛出:

  JobInterruptedException - if the step is interrupted externally

  UnexpectedJobExecutionException

• doExecutionRelease

  protected void doExecutionRelease()

  Releases the most recent StepExecution

• doExecutionRegistration

  protected void doExecutionRegistration​(StepExecution stepExecution)

  Registers the StepExecution for property resolution via StepScope

  参数:

  stepExecution - StepExecution to use when hydrating the StepScoped beans

• registerStepExecutionListener

  public void registerStepExecutionListener​(StepExecutionListener listener)

  Register a step listener for callbacks at the appropriate stages in a step execution.

  参数:

  listener - a StepExecutionListener

• setStepExecutionListeners

  public void setStepExecutionListeners​(StepExecutionListener[] listeners)

  Register each of the objects as listeners.

  参数:

  listeners - an array of listener objects of known types.

• getCompositeListener

  protected StepExecutionListener getCompositeListener()

  返回:

  composite listener that delegates to all registered listeners.

• setJobRepository

  public void setJobRepository​(JobRepository jobRepository)

  Public setter for JobRepository.

  参数:

  jobRepository - is a mandatory dependence (no default).

• getJobRepository

  protected JobRepository getJobRepository()

• toString

  public java.lang.String toString()

  覆盖:

  toString 在类中 java.lang.Object
