1、ChunkListener 
    Called before and after chunk execution
2、ItemProcessListener 
    Called before and after an ItemProcessor gets an item and when that processor throws an exception
3、ItemReadListener 
    Called before and after an item is read and when an
exception occurs reading an item
4、ItemWriteListener 
    Called before and after an item is written and when an exception occurs writing an item
5、SkipListener 
    Called when a skip occurs while reading, processing, or writing an item
6、StepExecutionListener 
    Called before and after a step

1、abstract 
    When  true, specifies that the job or step element isn’t a concrete element but an abstract one used only for configuration. Abstract configuration enti-
ties aren’t instantiated.
2、parent: 子元素继承了父元素所有的属性，当然子元素可以复写父元素的属性
    The parent element used to configure a given element. The child element has all properties of its parent and can override them.
