Interface BindingResult

All Superinterfaces:

Errors

All Known Implementing Classes:

AbstractBindingResult, AbstractPropertyBindingResult, BeanPropertyBindingResult, BindException, DirectFieldBindingResult, MapBindingResult

public interface BindingResult
extends Errors

General interface that represents binding results. Extends the interface for error registration capabilities, allowing for a Validator to be applied, and adds binding-specific analysis and model building.

Serves as result holder for a DataBinder, obtained via the DataBinder.getBindingResult() method. BindingResult implementations can also be used directly, for example to invoke a Validator on it (e.g. as part of a unit test).

2.0

Methods

Modifier and Type	Method and Description
void	addError(ObjectError error) Add a custom ObjectError or FieldError to the errors list.
PropertyEditor	findEditor(String field, Class<?> valueType) Find a custom property editor for the given type and property.
Map<String,Object>	getModel() Return a model Map for the obtained state, exposing a BindingResult instance as 'MODEL_KEY_PREFIX + objectName' and the object itself as 'objectName'.
org.springframework.beans.PropertyEditorRegistry	getPropertyEditorRegistry() Return the underlying PropertyEditorRegistry.
Object	getRawFieldValue(String field) Extract the raw field value for the given field.
String[]	getSuppressedFields() Return the list of fields that were suppressed during the bind process.
Object	getTarget() Return the wrapped target object, which may be a bean, an object with public fields, a Map - depending on the concrete binding strategy.
void	recordSuppressedField(String field) Mark the specified disallowed field as suppressed.
String[]	resolveMessageCodes(String errorCode) Resolve the given error code into message codes.
String[]	resolveMessageCodes(String errorCode, String field) Resolve the given error code into message codes for the given field.

Field Detail

MODEL_KEY_PREFIX

static final String MODEL_KEY_PREFIX

Prefix for the name of the BindingResult instance in a model, followed by the object name.

Method Detail

getTarget

Object getTarget()

Return the wrapped target object, which may be a bean, an object with public fields, a Map - depending on the concrete binding strategy.

getModel

Map<String,Object> getModel()

Return a model Map for the obtained state, exposing a BindingResult instance as 'MODEL_KEY_PREFIX + objectName' and the object itself as 'objectName'.

Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.

The attributes in the model Map returned by this method are usually included in the org.springframework.web.servlet.ModelAndView for a form view that uses Spring's bind tag in a JSP, which needs access to the BindingResult instance. Spring's pre-built form controllers will do this for you when rendering a form view. When building the ModelAndView instance yourself, you need to include the attributes from the model Map returned by this method.

getRawFieldValue

Object getRawFieldValue(String field)

Extract the raw field value for the given field. Typically used for comparison purposes.

Parameters:

field - the field to check

Returns:

the current value of the field in its raw form, or null if not known

findEditor

PropertyEditor findEditor(String field,
                        Class<?> valueType)

Find a custom property editor for the given type and property.

Parameters:

field - the path of the property (name or nested path), or null if looking for an editor for all properties of the given type

valueType - the type of the property (can be null if a property is given but should be specified in any case for consistency checking)

Returns:

the registered editor, or null if none

getPropertyEditorRegistry

org.springframework.beans.PropertyEditorRegistry getPropertyEditorRegistry()

Return the underlying PropertyEditorRegistry.

Returns:

the PropertyEditorRegistry, or null if none available for this BindingResult

addError

void addError(ObjectError error)

Add a custom ObjectError or FieldError to the errors list.

Intended to be used by cooperating strategies such as BindingErrorProcessor.

ObjectError, FieldError, BindingErrorProcessor

resolveMessageCodes

String[] resolveMessageCodes(String errorCode)

Resolve the given error code into message codes.

Calls the configured MessageCodesResolver with appropriate parameters.

Parameters:

errorCode - the error code to resolve into message codes

Returns:

the resolved message codes

resolveMessageCodes

String[] resolveMessageCodes(String errorCode,
                           String field)

Resolve the given error code into message codes for the given field.

Calls the configured MessageCodesResolver with appropriate parameters.

Parameters:

errorCode - the error code to resolve into message codes

field - the field to resolve message codes for

Returns:

the resolved message codes

recordSuppressedField

void recordSuppressedField(String field)

Mark the specified disallowed field as suppressed.

The data binder invokes this for each field value that was detected to target a disallowed field.

See Also:

DataBinder.setAllowedFields(java.lang.String...)

getSuppressedFields

String[] getSuppressedFields()

Return the list of fields that were suppressed during the bind process.

Can be used to determine whether any field values were targeting disallowed fields.

DataBinder.setAllowedFields(java.lang.String...)
