## org.springframework.web.bind.annotation
Annotation Type InitBinder

    @Target(value=METHOD)
    @Retention(value=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.

### value

    public abstract 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.

  Default:
    {}
