Java @DynamoDBIndexHashKey必须指定哈希GSI名称之一

我的课程如下

@DynamoDBTable(tableName = LogConstant.TableName)
public class Journal {

@DynamoDBIndexHashKey(attributeName = "event_type")
private String eventType;

@DynamoDBIndexHashKey(attributeName = "user_id",globalSecondaryIndexName = LogConstant.GlobalUserIdIndex)
private String userId;

@DynamoDBIndexHashKey(attributeName = "user_identifier", globalSecondaryIndexName = LogConstant.GlobalUserIdentifierIndex)
private String userIdentifier;

@DynamoDBIndexHashKey(attributeName = "order_id", globalSecondaryIndexName = LogConstant.GlobalOrderIdIndex)
private String orderId;

@DynamoDBTypeConvertedEnum
@DynamoDBAttribute(attributeName = "generated_by")
private GenertionType generatedBy;

@DynamoDBTypeConvertedEnum
@DynamoDBHashKey(attributeName = "interacting_service")
private InteractingService interactingSerice;

@DynamoDBAttribute(attributeName = "agent")
private String agent;

@DynamoDBAttribute(attributeName = "content")
private String content;

@DynamoDBRangeKey
@DynamoDBIndexRangeKey(attributeName = "created_at",
        globalSecondaryIndexNames = {LogConstant.GlobalUserIdIndex,LogConstant.GlobalUserIdentifierIndex,LogConstant.GlobalOrderIdIndex})
private String createdAt;

获取搜索结果的服务是

DynamoDBQueryExpression<Journal> expression = new 
DynamoDBQueryExpression<Journal>()
            .withIndexName(LogConstant.GlobalUserIdIndex)
            .withConsistentRead(false)
            .withHashKeyValues(journal);

    TableDescription table = DynamoDbStarter.getDynamoDB().getTable(LogConstant.TableName).describe();

    return DynamoDbStarter.getDynamoDBMapper().query(Journal.class, expression);

DynamoDBQueryExpression表达式=新建
DynamoDBQueryExpression（）
.withIndexName（LogConstant.GlobalUserIndex）
.withConsistentRead（假）
.withHashKeyValues（日记账）；
TableDescription table=DynamoDbStarter.getDynamoDB（）.getTable（LogConstant.TableName.description（）；
返回DynamoDbStarter.getDynamoDBMapper（）.query（Journal.class，expression）；

尽管insert工作正常，但在获取结果的过程中，我得到了一个异常

我有一个表，哈希键作为服务，范围键作为CreatedDate。我试图通过GSI获取结果，但不知怎的，它导致了一个异常

---

有人能看出我做错了什么吗？

您的异常消息说

@DynamoDBIndexHashKey must specify one of HASH GSI name/names

如果查看类中的所有

@dynamodbindeuthskey

注释，您将看到它们都为

globalSecondaryIndexName

设置了一个值，除了

eventType

上的注释。如果

eventType

应该是GSI哈希键，则需要设置此值。如果

eventType

不应该是GSI的哈希键，则需要从该字段中删除

@dynamodbindeuthskey

注释

---

有关使用

@DynamoDBImdexHashKey

的更多详细信息，请参阅。它必须如下所示：

@get:DynamoDBIndexHashKey(attributeName = "product", globalSecondaryIndexName = "product-index")
var product: String? = null

将此项也添加到DB定义中：

CreateTableRequest()

 ...

 .withGlobalSecondaryIndexes(GlobalSecondaryIndex()
            .withIndexName(PRODUCT_INDEX)
            .withKeySchema(
               KeySchemaElement(PRODUCT, KeyType.HASH),
               KeySchemaElement(PRODUCT_RANGE, KeyType.RANGE))
            .withProjection(Projection().withProjectionType(ProjectionType.ALL))
            .withProvisionedThroughput(ProvisionedThroughput(1L, 2L)))  

---

eventType

具有

@dynamodbindeuthskey

注释，但该注释缺少索引名。如果希望

eventType

作为主表的哈希键，则需要使用

@DynamoDBHashKey

。很抱歉，我错误地提到了事件类型，它是具有@DynamoDBHashKey注释的交互服务。对不起，我已经更新了问题。谢谢。我错过了。再次感谢您，它必须是这样的>@get:dynamodbindeuthskey（attributeName=“product”，globalSecondaryIndexName=“product index”）>var-product:String？=无效的
