所有已实现的接口:
ItemProcessor<I,O>, org.springframework.beans.factory.InitializingBean
```
public class ScriptItemProcessor<I,O>
extends java.lang.Object
implements ItemProcessor<I,O>, org.springframework.beans.factory.InitializingBean
```
ItemProcessor implementation that passes the current item to process to the provided script. Exposes the current item for processing via the ITEM_BINDING_VARIABLE_NAME key name ("item"). A custom key name can be set by invoking: setItemBindingVariableName(java.lang.String) with the desired key name. The thread safety of this ItemProcessor depends on the implementation of the ScriptEvaluator used.

`void`	`afterPropertiesSet()`
`O`	`process(I item)`	Process the provided item, returning a potentially modified or new item for continued processing.
`void`	`setItemBindingVariableName(java.lang.String itemBindingVariableName)`	Provides the ability to change the key name that scripts use to obtain the current item to process if the variable represented by: `ITEM_BINDING_VARIABLE_NAME` is not suitable ("item").
`void`	`setScript(org.springframework.core.io.Resource resource)`	Sets the `Resource` location of the script to use.
`void`	`setScriptEvaluator(org.springframework.scripting.ScriptEvaluator scriptEvaluator)`	Provides the ability to set a custom `ScriptEvaluator` implementation.

    从接口复制的说明: ItemProcessor
    Process the provided item, returning a potentially modified or new item for continued processing. If the returned result is null, it is assumed that processing of the item should not continue.
    指定者:
    process 在接口中 ItemProcessor<I,O>
    参数:
    item - to be processed
    返回:
    potentially modified or new item for continued processing, null if processing of the provided item should not continue.
    抛出:
    java.lang.Exception - thrown if exception occurs during processing.
  - setScript
```
public void setScript(org.springframework.core.io.Resource resource)
```
    Sets the Resource location of the script to use. The script language will be deduced from the filename extension.
    参数:
    resource - the Resource location of the script to use.
  - setScriptSource
```
public void setScriptSource(java.lang.String scriptSource,
                            java.lang.String language)
```
    Sets the provided String as the script source code to use.
    参数:
    scriptSource - the String form of the script source code to use.
    language - the language of the script.
  - setItemBindingVariableName
```
public void setItemBindingVariableName(java.lang.String itemBindingVariableName)
```
    Provides the ability to change the key name that scripts use to obtain the current item to process if the variable represented by: ITEM_BINDING_VARIABLE_NAME is not suitable ("item").
    参数:
    itemBindingVariableName - the desired binding variable name
  - setScriptEvaluator
```
public void setScriptEvaluator(org.springframework.scripting.ScriptEvaluator scriptEvaluator)
```
    Provides the ability to set a custom ScriptEvaluator implementation. If not set, a StandardScriptEvaluator will be used by default.
    参数:
    scriptEvaluator - the ScriptEvaluator to use
  - 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
