Annotation Type InitBinder



  • @Target(value=METHOD)

     @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.

        public abstract java.lang.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:
        {}
