DefaultDataBinderFactory

public DefaultDataBinderFactory(@Nullable
 WebBindingInitializer initializer)

Create a new DefaultDataBinderFactory instance.

Parameters:

initializer - for global data binder initialization (or null if none)

setMethodValidationApplicable

public void setMethodValidationApplicable(boolean methodValidationApplicable)

Configure flag to signal whether validation will be applied to handler method arguments, which is the case if Bean Validation is enabled in Spring MVC, and method parameters have @Constraint annotations.

createBinder

public final WebDataBinder createBinder(NativeWebRequest webRequest,
 @Nullable
 Object target,
 String objectName)
                                 throws Exception

Create a new WebDataBinder for the given target object and initialize it through a WebBindingInitializer.

Specified by:

createBinder in interface WebDataBinderFactory

Parameters:

webRequest - the current request

target - the object to create a data binder for, or null if creating a binder for a simple type

objectName - the name of the target object

Returns:

the created WebDataBinder instance, never null

Throws:

Exception - in case of invalid state or arguments

createBinder

public final WebDataBinder createBinder(NativeWebRequest webRequest,
 @Nullable
 Object target,
 String objectName,
 ResolvableType type)
                                 throws Exception

Variant of WebDataBinderFactory.createBinder(NativeWebRequest, Object, String) with a ResolvableType for which the DataBinder is created. This may be used to construct the target, or otherwise provide more insight on how to initialize the binder..

By default, if the parameter has @Valid, Bean Validation is excluded, deferring to method validation.

Specified by:

createBinder in interface WebDataBinderFactory

Throws:

Exception

createBinderInstance

protected WebDataBinder createBinderInstance(@Nullable
 Object target,
 String objectName,
 NativeWebRequest webRequest)
                                      throws Exception

Extension point to create the WebDataBinder instance. By default, this is WebRequestDataBinder.

Parameters:

target - the binding target or null for type conversion only

objectName - the binding target object name

webRequest - the current request

Throws:

Exception - in case of invalid state or arguments

initBinder

protected void initBinder(WebDataBinder dataBinder,
 NativeWebRequest webRequest)
                   throws Exception

Extension point to further initialize the created data binder instance (e.g. with @InitBinder methods) after "global" initialization via WebBindingInitializer.

Parameters:

dataBinder - the data binder instance to customize

webRequest - the current request

Throws:

Exception - if initialization fails
