ConfigurableWebBindingInitializer

Convenient WebBindingInitializer for declarative configuration in a Spring application context. Allows for reusing pre-configured initializers with multiple controller/handlers.

DefaultDataBinderFactory

Create a WebRequestDataBinder instance and initialize it with a WebBindingInitializer.

DefaultSessionAttributeStore

Default implementation of the SessionAttributeStore interface, storing the attributes in the WebRequest session (i.e. HttpSession or PortletSession).

SimpleSessionStatus

Simple implementation of the SessionStatus interface, keeping the complete flag as an instance variable.

SpringWebConstraintValidatorFactory

JSR-303 ConstraintValidatorFactory implementation that delegates to the current Spring WebApplicationContext for creating autowired ConstraintValidator instances.

In contrast to org.springframework.validation.beanvalidation.SpringConstraintValidatorFactory, this variant is meant for declarative use in a standard validation.xml file, e.g. in combination with JAX-RS or JAX-WS.

WebArgumentResolver

SPI for resolving custom arguments for a specific handler method parameter. Typically implemented to detect special parameter types, resolving well-known argument values for them.

A typical implementation could look like as follows:

 public class MySpecialArgumentResolver implements WebArgumentResolver { public Object resolveArgument(MethodParameter methodParameter, NativeWebRequest webRequest) { if (methodParameter.getParameterType().equals(MySpecialArg.class)) { return new MySpecialArg("myValue"); } return UNRESOLVED; } }

WebDataBinderFactory

A factory for creating a WebDataBinder instance for a named target object.

WebExchangeDataBinder

Specialized org.springframework.validation.DataBinder to perform data binding from URL query params or form data in the request data to Java objects.

WebRequestDataBinder

Special org.springframework.validation.DataBinder to perform data binding from web request parameters to JavaBeans, including support for multipart files.

See the DataBinder/WebDataBinder superclasses for customization options, which include specifying allowed/required fields, and registering custom property editors.

Can also used for manual data binding in custom web controllers or interceptors that build on Spring's org.springframework.web.context.request.WebRequest abstraction: e.g. in a org.springframework.web.context.request.WebRequestInterceptor implementation. Simply instantiate a WebRequestDataBinder for each binding process, and invoke bind with the current WebRequest as argument:

 MyBean myBean = new MyBean(); // apply binder to custom target object WebRequestDataBinder binder = new WebRequestDataBinder(myBean); // register custom editors, if desired binder.registerCustomEditor(...); // trigger actual binding of request parameters binder.bind(request); // optionally evaluate binding errors Errors errors = binder.getErrors(); ...

WebExchangeBindException

A specialization of ServerWebInputException thrown when after data binding and validation failure. Implements BindingResult (and its super-interface Errors) to allow for direct analysis of binding and validation errors.
