So verwenden Sie benutzerdefinierte Annotation auf Sammlertyp Ebene im Frühjahr mvc

Question

Ich habe meine benutzerdefinierte Annotation und seine Constraint-Validator hinzugefügt, um Listeneingaben auf PersonForm zu validieren, aber wenn es darum geht, eine Ausnahme zu testen, löst es Datenbindung Meine Anfrage gesendet werfen ajax call + form.serialize();

PersonForm:

private Long id; 

@NotEmpty 
private String firstName; 

@NotEmpty 
private String lastName; 

@Email(message = "profile.email.email") 
private String email; 

private List<@ResourceConstraint String> resource; 

// all setters/getters .... 

Annotation

@Documented 
@Constraint(validatedBy = ResourceValidator.class) 
@Target({ElementType.TYPE_USE}) 
@Retention(RetentionPolicy.RUNTIME) 
@NotEmpty 
public @interface ResourceConstraint { 

    String message() default "resource not Valid"; 
    Class<?>[] groups() default {}; 
    Class<? extends Payload>[] payload() default {}; 
} 

Constraint Validator

public class ResourceValidator implements ConstraintValidator<ResourceConstraint, String> { 

    @Override 
    public boolean isValid(String value, ConstraintValidatorContext context) { 
     boolean result = false; 
      if(Enums.getIfPresent(Resource.class, value.toUpperCase()).isPresent()) { 
        result = true; 
      } 
     return result; 
    } 

} 

-Controller

@PostMapping(path = "/applay/profile/{id}", produces = "application/json;charset=UTF-8") 
public @ResponseBody JsonResponseBean applayProfile(@PathVariable Long id, @Valid PersonForm form, BindingResult result, Locale locale) throws BusinessException { 
    JsonResponseBean jsonResponse = new JsonResponseBean(); 
    Person current = new Person(); 

    if (!result.hasErrors()) { 
     ... 

    } else { 
     ... 
    } 

    return jsonResponse; 
} 

Ausnahme

java.lang.IllegalStateException: JSR-303 validated property 'resource[1].<list element>' does not have a corresponding accessor for Spring data binding - check your DataBinder's configuration (bean property versus direct field access)

wie Recht, den benutzerdefinierten Validator Prozess Alle Getter und Setter von PersonForm zu binden, nach hibernate doc umgesetzt werden ich brauche nicht irgend etwas mehr als die Einschränkung

Abhängigkeiten (Gradle) Anwendung

compile group: 'javax.validation', name: 'validation-api', version: '2.0.0.Final' 
    compile group: 'org.hibernate.validator', name: 'hibernate-validator', version: '6.0.2.Final' 
... 

Answer 1

ich habe es, um sich mit diesem Fehler zu

Upgrade loszuwerden

spring Version  = '5.0.1.RELEASE' 
hibernate Version = '5.2.12.Final' 

with 
compile group: 'javax.validation', name: 'validation-api', version: '2.0.0.Final' 
compile group: 'org.hibernate.validator', name: 'hibernate-validator', version: '6.0.4.Final'
