void validate(Object target, Errors errors, Object... validationHints)
Validate the suppliedtarget

for which theValidator.supports(Class)
method typically returnstrue
.The supplied
errors
instance can be used to report any resulting validation errors.This variant of
validate()
supports validation hints, such as validation groups against a JSR-303 provider (in which case, the provided hint objects need to be annotation arguments of typeClass
).Note: Validation hints may get ignored by the actual target
Validator
, in which case this method should behave just like its regularValidator.validate(Object, Errors)
sibling.- Parameters:
target
- the object that is to be validatederrors
- contextual state about the validation processvalidationHints
- one or more hint objects to be passed to the validation engine- See Also:
Validator.validate(Object, Class[])
validateValue
default void validateValue(Class<?> targetType, String fieldName, @Nullable Object value, Errors errors, Object... validationHints)
Validate the supplied value for the specified field on the target type, reporting the same validation errors as if the value would be bound to the field on an instance of the target class.- Parameters:
targetType
- the target typefieldName
- the name of the fieldvalue
