所有已实现的接口:
StepExecutionListener, StepListener, org.springframework.beans.factory.InitializingBean
```
public class ExecutionContextPromotionListener
extends StepExecutionListenerSupport
implements org.springframework.beans.factory.InitializingBean
```
This class can be used to automatically promote items from the StepExecutionContext to the JobExecutionContext at the end of a step. A list of keys should be provided that correspond to the items in the StepExecutionContext that should be promoted. Additionally, an optional list of statuses can be set to indicate for which exit status codes the promotion should occur. These statuses will be checked using the PatternMatcher, so wildcards are allowed. By default, promotion will only occur for steps with an exit code of "COMPLETED".

    从接口复制的说明: StepExecutionListener
    Give a listener a chance to modify the exit status from a step. The value returned will be combined with the normal exit status using ExitStatus.and(ExitStatus). Called after execution of step's processing logic (both successful or failed). Throwing exception in this method has no effect, it will only be logged.
    指定者:
    afterStep 在接口中 StepExecutionListener
    覆盖:
    afterStep 在类中 StepExecutionListenerSupport
    参数:
    stepExecution - StepExecution instance.
    返回:
    an ExitStatus to combine with the normal value. Return null to leave the old value unchanged.
  - 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
  - setKeys
```
public void setKeys(java.lang.String[] keys)
```
    参数:
    keys - A list of keys corresponding to items in the StepExecutionContext that must be promoted.
  - setStatuses
```
public void setStatuses(java.lang.String[] statuses)
```
    参数:
    statuses - A list of statuses for which the promotion should occur. Statuses can may contain wildcards recognizable by a PatternMatcher.
  - setStrict
```
public void setStrict(boolean strict)
```
    If set to TRUE, the listener will throw an exception if any 'key' is not found in the Step ExecutionContext. FALSE by default.
    参数:
    strict - boolean the value of the flag.
