Annotation Type MvcBinding
-
@Retention(RUNTIME) @Target({PARAMETER,METHOD,FIELD}) @Documented public @interface MvcBinding
This annotation is used to enable Jakarta MVC-specific binding rules for a Jakarta RESTful Web Services parameter binding. It can be placed on fields and method parameters together with Jakarta RESTful Web Services binding annotations such asFormParam,QueryParam, etc.MVC parameter binding differs from traditional Jakarta RESTful Web Services parameter binding in the following aspects:
- In Jakarta RESTful Web Services binding and validation errors result in an exception being thrown which can
only be handled by a corresponding exception mapper. This usually doesn't make sense for web
applications, because errors must be processed by the controller, so they can be
displayed on the resulting HTML page. In case of Jakarta MVC bindings such errors don't prevent the controller
from being invoked and are instead made available via the injectable
BindingResultclass. - Jakarta RESTful Web Services parameter type conversion isn't locale-aware. The standard Jakarta RESTful Web Services converters
always use a fixed locale to parse numbers and dates. In MVC applications users typically
enter data into forms in their native locale. Therefore, Jakarta MVC bindings perform data type
conversion by respecting the request locale resolved via
LocaleResolver.
