类 StepContext

构造器详细资料

• StepContext

  public StepContext​(StepExecution stepExecution)

  Create a new instance of StepContext for this StepExecution.

  参数:

  stepExecution - a step execution

• StepContext

  public StepContext​(StepExecution stepExecution,
                     BatchPropertyContext propertyContext)

方法详细资料

• getStepName

  public java.lang.String getStepName()

  Convenient accessor for current step name identifier. Usually this is the same as the bean name of the step that is executing (but might not be e.g. in a partition).

  返回:

  the step name identifier of the current StepExecution

• getJobName

  public java.lang.String getJobName()

  Convenient accessor for current job name identifier.

  返回:

  the job name identifier of the enclosing JobInstance associated with the current StepExecution

• getSystemProperties

  public java.util.Properties getSystemProperties()

  Convenient accessor for System properties to make it easy to access them from placeholder expressions.

  返回:

  the current System properties

• getStepExecutionContext

  public java.util.Map<java.lang.String,​java.lang.Object> getStepExecutionContext()

  返回:

  a map containing the items from the step ExecutionContext

• getJobExecutionContext

  public java.util.Map<java.lang.String,​java.lang.Object> getJobExecutionContext()

  返回:

  a map containing the items from the job ExecutionContext

• getJobParameters

  public java.util.Map<java.lang.String,​java.lang.Object> getJobParameters()

  返回:

  a map containing the items from the JobParameters

• getPartitionPlan

  public java.util.Map<java.lang.String,​java.lang.Object> getPartitionPlan()

• registerDestructionCallback

  public void registerDestructionCallback​(java.lang.String name,
                                          java.lang.Runnable callback)

  Allow clients to register callbacks for clean up on close.

  参数:

  name - the callback id (unique attribute key in this context)

  callback - a callback to execute on close

• removeAttribute

  @Nullable
  public java.lang.Object removeAttribute​(java.lang.String name)

  Override base class behaviour to ensure destruction callbacks are unregistered as well as the default behaviour.

  指定者:

  removeAttribute 在接口中 org.springframework.core.AttributeAccessor

  覆盖:

  removeAttribute 在类中 SynchronizedAttributeAccessor

  另请参阅:

  SynchronizedAttributeAccessor.removeAttribute(String)

• close

  public void close()

  Clean up the context at the end of a step execution. Must be called once at the end of a step execution to honour the destruction callback contract from the StepScope.

• getStepExecution

  public StepExecution getStepExecution()

  The current StepExecution that is active in this context.

  返回:

  the current StepExecution

• getId

  public java.lang.String getId()

  返回:

  unique identifier for this context based on the step execution

• equals

  public boolean equals​(java.lang.Object other)

  Extend the base class method to include the step execution itself as a key (i.e. two contexts are only equal if their step executions are the same).

  覆盖:

  equals 在类中 SynchronizedAttributeAccessor

  另请参阅:

  SynchronizedAttributeAccessor.equals(Object)

• hashCode

  public int hashCode()

  Overrides the default behaviour to provide a hash code based only on the step execution.

  覆盖:

  hashCode 在类中 SynchronizedAttributeAccessor

  另请参阅:

  SynchronizedAttributeAccessor.hashCode()

• toString

  public java.lang.String toString()

  覆盖:

  toString 在类中 SynchronizedAttributeAccessor
