我已经添加了4个自定义验证器，以便在我的控制器中进行一些检查。其中3个在工作，但是 ValidObjectIdentity 一个不行。
这是我的constraint-mapping.xml

<constraint-mappings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                     xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/mapping validation-mapping-1.1.xsd"
                     xmlns="http://jboss.org/xml/ns/javax/validation/mapping" version="1.1">

    <bean class="org.springframework.security.acls.domain.AccessControlEntryImpl" ignore-annotations="true">
        <field name="sid">
            <constraint annotation="javax.validation.constraints.NotNull"/>
            <constraint annotation="package.validation.SidExists"/>
            <constraint annotation="package.validation.NonMatchingSid"/>
        </field>
        <field name="acl">
            <constraint annotation="javax.validation.constraints.NotNull"/>
        </field>
    </bean>

    <bean class="org.springframework.security.acls.domain.AclImpl">
        <field name="objectIdentity">
            <constraint annotation="javax.validation.constraints.NotNull"/>
            <constraint annotation="package.validation.ValidObjectIdentity"/>
        </field>
    </bean>

    <bean class="package.AccessControlEntryController">
        <method name="create">
            <parameter type="org.springframework.security.acls.model.AccessControlEntry">
                <constraint annotation="package.validation.ValidEntry"/>
            </parameter>
        </method>
    </bean>
</constraint-mappings>

@RestController
@RequestMapping(value = "/acl")
@Validated
public class AccessControlEntryController {

    @ResponseBody
    @RequestMapping(value = "/entry", method = RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    public AccessControlEntry create(@Valid @RequestBody AccessControlEntry entry){
        return aclService.createAccessControlEntry(entry);
    }
}

为了便于参考，我将把 AccessControlEntryImpl 以及 AclImpl ```
public class AccessControlEntryImpl implements AccessControlEntry, AuditableAccessControlEntry {

private final Acl acl;
private Permission permission;
private final Serializable id;
private final Sid sid;
private boolean auditFailure = false;
private boolean auditSuccess = false;
private final boolean granting;

}

public class AclImpl implements Acl, MutableAcl, AuditableAcl, OwnershipAcl {
private Acl parentAcl;
private transient AclAuthorizationStrategy aclAuthorizationStrategy;
private transient PermissionGrantingStrategy permissionGrantingStrategy;
private final List aces = new ArrayList<>();
private ObjectIdentity objectIdentity;
private Serializable id;
private Sid owner; // OwnershipAcl
private List loadedSids = null;
}

我可以看到正在工作的验证器与accesscontrolentry直接相关，但是 `ObjectIdentity` 与班级有关 `Acl` . 尽管 `AccessControlEntry` 有 `Acl` 类本身不会进入验证程序。有没有办法验证 `ObjectIdentity` 像其他人一样？
这是一个验证器，如果你想看的话

@Target(value = ElementType.FIELD)
@Retention(value = RetentionPolicy.RUNTIME)
@Constraint(validatedBy = ValidObjectIdentityValidator.class)
public @interface ValidObjectIdentity {

String message() default "{package.ValidObjectIdentity.message}";

Class<?>[] groups() default {};

Class<? extends Payload>[] payload() default {};

}

public class ValidObjectIdentityValidator implements ConstraintValidator<ValidObjectIdentity, ObjectIdentity> {

@Override
public boolean isValid(ObjectIdentity identity, ConstraintValidatorContext context) {
  // Logic
}

}
