Method Details

getDetailMessageArguments

public Object[] getDetailMessageArguments(MessageSource messageSource,
 Locale locale)

Description copied from interface: ErrorResponse

Variant of ErrorResponse.getDetailMessageArguments() that uses the given MessageSource for resolving the message argument values.

This is useful for example to expand message codes from validation errors.

The default implementation delegates to ErrorResponse.getDetailMessageArguments(), ignoring the supplied MessageSource and Locale.

Specified by:

getDetailMessageArguments in interface ErrorResponse

Parameters:

messageSource - the MessageSource to use for the lookup

locale - the Locale to use for the lookup

getDetailMessageArguments

public Object[] getDetailMessageArguments()

Description copied from interface: ErrorResponse

Return arguments to use along with a message code to resolve the problem "detail" for this exception through a MessageSource. The arguments are expanded into placeholders of the message value, e.g. "Invalid content type {0}".

Specified by:

getDetailMessageArguments in interface ErrorResponse

Overrides:

getDetailMessageArguments in class ErrorResponseException

getTarget

public Object getTarget()

Description copied from interface: MethodValidationResult

Return the target of the method invocation to which validation was applied.

Specified by:

getTarget in interface MethodValidationResult

getMethod

public Method getMethod()

Description copied from interface: MethodValidationResult

Return the method to which validation was applied.

Specified by:

getMethod in interface MethodValidationResult

isForReturnValue

public boolean isForReturnValue()

Description copied from interface: MethodValidationResult

Whether the violations are for a return value. If true the violations are from validating a return value. If false the violations are from validating method arguments.

Specified by:

isForReturnValue in interface MethodValidationResult

getParameterValidationResults

public List<ParameterValidationResult> getParameterValidationResults()

Description copied from interface: MethodValidationResult

Return all validation results per method parameter, including both MethodValidationResult.getValueResults() and MethodValidationResult.getBeanResults().

Use MethodValidationResult.getCrossParameterValidationResults() for access to errors from cross-parameter validation.

Specified by:

getParameterValidationResults in interface MethodValidationResult

See Also:

• MethodValidationResult.getValueResults()
• MethodValidationResult.getBeanResults()

getCrossParameterValidationResults

public List<MessageSourceResolvable> getCrossParameterValidationResults()

Description copied from interface: MethodValidationResult

Return errors from cross-parameter validation.

Specified by:

getCrossParameterValidationResults in interface MethodValidationResult

visitResults

public void visitResults(HandlerMethodValidationException.Visitor visitor)

Provide a Visitor to handle ParameterValidationResults through callback methods organized by controller method parameter type.
