Question

我在需要多种查询类型的分页中使用Spring Boot和DynamoDB：

OrganizationID（哈希键“ HK”）和PersonId（RangeKey“ RK”）->返回一个
PersonID（RK）->返回与人员相关联的组织
OrganizationID（HK）和SortKey（RK）->返回组织内的人员并启用分页。

实体和存储库类在这里：

["Coke": ["1", "80"], "Appetizer": ["3", "70"], "Water": ["4", "70"],

"Noodle": ["2", "40"], "Pizza": ["7", "80"],  "Steak": ["7", "60"]]

和

cd /path/to/tensorflow-models/research/slim
# export inference graph, success
python export_inference_graph.py --alsologtostderr --model_name=resnet_v1_50 --output_file=resnet_v1_50_inf_graph.pb
# freeze the inference graph with the trained weights, failed
python ~/.local/lib/python2.7/site-packages/tensorflow/python/tools/freeze_graph.py \
    --input_graph=resnet_v1_50_inf_graph.pb \
    --input_checkpoint=/path/to/models/resnet_v1_50.ckpt \
    --input_binary=true --output_graph=frozen_resnet_v1_50.pb \
    --output_node_names=resnet_v1_50/predictions/Reshape

现在，如果我尝试使用以下方法查询findAllByOrganizationId（UUID OrganizationId，Pageable pageable）：

@DynamoDBTable(tableName = "organizationPersons")
public class OrganizationPersonsEntity {

    @Id
    private OrganizationPersonsEntityId id;

    private UUID organizationId;
    private UUID personId;
    private String type;
    private String sortKey;
    private String personSortName;

    public OrganizationPersonsEntity(){

    }

    public OrganizationPersonsEntity(UUID orgnizationId, UUID personId) {
        setOrganizationId(orgnizationId);
        setPersonId(personId);
    }


    public OrganizationPersonsEntity(UUID orgnizationId, UUID personId, String type, String personSortName) {
        setOrganizationId(orgnizationId);
        setPersonId(personId);
        this.type = type;
        this.personSortName = personSortName;
    }

    @DynamoDBHashKey
    @DynamoDBIndexHashKey(globalSecondaryIndexName = "sortIndex")
    public UUID getOrganizationId() {
        return id != null ? id.getOrganizationId() : null;
    }

    public void setOrganizationId(UUID orgnizationId) {
        if (id == null) {
            id = new OrganizationPersonsEntityId();
        }
        this.id.setOrganizationId(orgnizationId);
    }

    @DynamoDBRangeKey
    @DynamoDBIndexHashKey(globalSecondaryIndexName = "personIndex")
    public UUID getPersonId() {
        return id != null ? id.getPersonId(): null;
    }

    public void setPersonId(UUID personId) {
        if (id == null) {
            id = new OrganizationPersonsEntityId();
        }
        this.id.setPersonId(personId);
    }

    @DynamoDBAttribute
    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    @DynamoDBIndexRangeKey(globalSecondaryIndexNames = {"sortIndex"})
    public String getSortKey() {
        if (sortKey == null) {
            return personSortName + "-" + id.organizationId + "-" + id.personId;
        } else {
            return sortKey;
        }
    }

    public void setSortKey(String sortKey) {
        this.sortKey = sortKey;
    }

    public static class OrganizationPersonsEntityId implements Serializable {
        private static final long serialVersionUID = 1L;

        private UUID organizationId;
        private UUID personId;

        public OrganizationPersonsEntityId() {
        }

        public OrganizationPersonsEntityId(UUID organizationId, UUID personId) {
            this.organizationId = organizationId;
            this.personId = personId;
        }

        @DynamoDBHashKey
        public UUID getOrganizationId() {
            return organizationId;
        }

        public void setOrganizationId(UUID id) {
            this.organizationId = id;
        }

        @DynamoDBRangeKey
        public UUID getPersonId() {
            return personId;
        }

        public void setPersonId(UUID personId) {
            this.personId = personId;
        }
    }
}

我得到一个错误，即使“ sortKey”定义为IndexRangeKey，也只能对personId进行排序。

@Repository
public interface OrganizationPersonsRepository extends 
DynamoDBPagingAndSortingRepository<OrganizationPersonsEntity, UUID> {

    Optional<List<OrganizationPersonsEntity>> findAllByPersonId(UUID personId);

    Page<OrganizationPersonsEntity> findAllByOrganizationId(UUID organizationId, Pageable pageable);

    Page<OrganizationPersonsEntity> findAllByOrganizationIdAndSortKeyBetween(UUID organizationId, String after, String before, Pageable pageRequest);

    Page<OrganizationPersonsEntity> findAllByOrganizationIdAndSortKeyGreaterThanEqual(UUID organizationId, String after, Pageable pageRequest);

    Page<OrganizationPersonsEntity> findAllByOrganizationIdAndSortKeyLessThanEqual(UUID organizationId, String before, Pageable pageRequest);

    OrganizationPersonsEntity findByOrganizationIdAndPersonId(UUID organizationId, UUID personId);

    default RepositoryPagingQuery<OrganizationPersonsEntity> findAllByOrganizationIdQuery(UUID organization) {
        return (after, before, limit, ascending) -> {
            PageRequest pageRequest = PageRequest.of(0, limit, ascending ? Sort.Direction.ASC : Sort.Direction.DESC, "sortKey");
            if (after != null && before != null) {
                return findAllByOrganizationIdAndSortKeyBetween(organization, after, before, pageRequest).getContent();
            } else if (after != null) {
                return findAllByOrganizationIdAndSortKeyGreaterThanEqual(organization, after, pageRequest).getContent();
            } else if (before != null) {
                return findAllByOrganizationIdAndSortKeyLessThanEqual(organization, before, pageRequest).getContent();
            } else {
                return findAllByOrganizationId(organization, pageRequest).getContent();
            }
        };
    }
}

我希望有人能够提供帮助，谢谢。

DynamoDB在查询中找不到sortKey
