ExceptionHandler (Spring Batch 4.1.4.RELEASE API)

所有已知实现类:

```
public interface ExceptionHandler
```
Handler to allow strategies for re-throwing exceptions. Normally a CompletionPolicy will be used to decide whether to end a batch when there is no exception, and the ExceptionHandler is used to signal an abnormal ending - an abnormal ending would result in an ExceptionHandler throwing an exception. The caller will catch and re-throw it if necessary.
