@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.

The names of command/form attributes and/or request parameters that this init-binder method is supposed to apply to. |
public abstract String[] value
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.
