ValidatingItemProcessor (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.item.validator.ValidatingItemProcessor<T>

所有已实现的接口:
ItemProcessor<T,T>, org.springframework.beans.factory.InitializingBean
直接已知子类:
BeanValidatingItemProcessor
```
public class ValidatingItemProcessor<T>
extends java.lang.Object
implements ItemProcessor<T,T>, org.springframework.beans.factory.InitializingBean
```
Simple implementation of ItemProcessor that validates input and returns it without modifications. Should the given Validator throw a ValidationException this processor will re-throw it to indicate the item should be skipped, unless setFilter(boolean) is set to true, in which case null will be returned to indicate the item should be filtered.

```
public void setValidator(Validator<? super T> validator)
```
    Set the validator used to validate each item.
    参数:

    Should the processor filter invalid records instead of skipping them?
    参数:
    filter - if set to true, items that fail validation are filtered (null is returned). Otherwise, a ValidationException will be thrown.

```
public T process(T item)
          throws ValidationException
```
    Validate the item and return it unmodified
    指定者:
    process 在接口中 ItemProcessor<T,T>
    参数:
    item - to be processed
    返回:
    the input item
    抛出:
