Constructor Details

MethodArgumentNotValidException

public MethodArgumentNotValidException(MethodParameter parameter,
 BindingResult bindingResult)

Constructor for MethodArgumentNotValidException.

Parameters:

parameter - the parameter that failed validation

bindingResult - the results of the validation

Method Details

getParameter

public final MethodParameter getParameter()

Return the method parameter that failed validation.

getStatusCode

public HttpStatusCode getStatusCode()

Description copied from interface: ErrorResponse

Return the HTTP status code to use for the response.

Specified by:

getStatusCode in interface ErrorResponse

getBody

public ProblemDetail getBody()

Description copied from interface: ErrorResponse

Return the body for the response, formatted as an RFC 9457 ProblemDetail whose status should match the response status.

Note: The returned ProblemDetail may be updated before the response is rendered, for example, via ErrorResponse.updateAndGetBody(MessageSource, Locale). Therefore, implementing methods should use an instance field, and should not re-create the ProblemDetail on every call, nor use a static variable.

Specified by:

getBody in interface ErrorResponse

getDetailMessageArguments

public Object[] getDetailMessageArguments(MessageSource source,
 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:

source - 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, for example, "Invalid content type {0}".

Specified by:

getDetailMessageArguments in interface ErrorResponse

getMessage

public String getMessage()

Description copied from class: BindException

Returns diagnostic information about the errors held in this object.

Overrides:

getMessage in class BindException
