InitBinder (Spring Framework 4.3.30.RELEASE API)

```
@Target(METHOD)
@Retention(RUNTIME)
@Documented
public @interface InitBinder
```
Annotation that identifies methods which initialize the WebDataBinder which will be used for populating command and form object arguments of annotated handler methods.
Such init-binder methods support all arguments that RequestMapping supports, except for command/form objects and corresponding validation result objects. Init-binder methods must not have a return value; they are usually declared as void.
Typical arguments are WebDataBinder in combination with WebRequest or Locale, allowing to register context-specific editors.

String[] value
```
    The names of command/form attributes and/or request parameters that this init-binder method is supposed to apply to.
    Default is to apply to all command/form attributes and all request parameters processed by the annotated handler class. Specifying model attribute names or request parameter names here restricts the init-binder method to those specific attributes/parameters, with different init-binder methods typically applying to different groups of attributes or parameters.
