Package org.springframework.validation.method

Class ParameterValidationResult

java.lang.Object

org.springframework.validation.method.ParameterValidationResult

Direct Known Subclasses:

ParameterErrors

public class ParameterValidationResult
extends Object

Store and expose the results of method validation for a method parameter.

• Validation errors directly on method parameter values are exposed as a list of MessageSourceResolvables.
• Nested validation errors on an Object method parameter are exposed as Errors by the subclass ParameterErrors.

6.1

Constructor Details

ParameterValidationResult

public ParameterValidationResult(MethodParameter param,
 @Nullable
 Object arg,
 Collection<? extends MessageSourceResolvable> errors)

Create a ParameterValidationResult.

Method Details

getMethodParameter

public MethodParameter getMethodParameter()

The method parameter the validation results are for.

getArgument

@Nullable
public Object getArgument()

The method argument value that was validated.

getResolvableErrors

public List<MessageSourceResolvable> getResolvableErrors()

List of MessageSourceResolvable representations adapted from the validation errors of the validation library.

• For a constraints directly on a method parameter, error codes are based on the names of the constraint annotation, the object, the method, the parameter, and parameter type, e.g. ["Max.myObject#myMethod.myParameter", "Max.myParameter", "Max.int", "Max"]. Arguments include the parameter itself as a MessageSourceResolvable, e.g. ["myObject#myMethod.myParameter", "myParameter"], followed by actual constraint annotation attributes (i.e. excluding "message", "groups" and "payload") in alphabetical order of attribute names.
• For cascaded constraints via @Valid on a bean method parameter, this method returns field errors that you can also access more conveniently through methods of the ParameterErrors sub-class.
