`void`	`afterPropertiesSet()`	Assert that mandatory properties are set (stepExecutionSplitter, partitionHandler) and delegate top superclass.

public PartitionStep()

  - setPartitionHandler
```
public void setPartitionHandler(PartitionHandler partitionHandler)
```
    A PartitionHandler which can send out step executions for remote processing and bring back the results.
    参数:
    partitionHandler - the PartitionHandler to set
  - setStepExecutionAggregator
```
public void setStepExecutionAggregator(StepExecutionAggregator stepExecutionAggregator)
```
    A StepExecutionAggregator that can aggregate step executions when they come back from the handler. Defaults to a DefaultStepExecutionAggregator.
    参数:
    stepExecutionAggregator - the StepExecutionAggregator to set
  - setStepExecutionSplitter
```
public void setStepExecutionSplitter(StepExecutionSplitter stepExecutionSplitter)
```
    Public setter for mandatory property StepExecutionSplitter.
    参数:
    stepExecutionSplitter - the StepExecutionSplitter to set
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws java.lang.Exception
```
    Assert that mandatory properties are set (stepExecutionSplitter, partitionHandler) and delegate top superclass.
    指定者:
    afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean
    覆盖:
    afterPropertiesSet 在类中 AbstractStep
    抛出:
    java.lang.Exception
    另请参阅:
    AbstractStep.afterPropertiesSet()
  - doExecute
```
protected void doExecute(StepExecution stepExecution)
                  throws java.lang.Exception
```
    Delegate execution to the PartitionHandler provided. The StepExecution passed in here becomes the parent or master execution for the partition, summarising the status on exit of the logical grouping of work carried out by the PartitionHandler. The individual step executions and their input parameters (through ExecutionContext) for the partition elements are provided by the StepExecutionSplitter.
    指定者:
    doExecute 在类中 AbstractStep
    参数:
    stepExecution - the master step execution for the partition
    抛出:
    java.lang.Exception - checked exception thrown by implementation
    另请参阅:
    Step.execute(StepExecution)
  - getStepExecutionSplitter
```
protected StepExecutionSplitter getStepExecutionSplitter()
```
  - getPartitionHandler
```
protected PartitionHandler getPartitionHandler()
