我的課程如下@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;獲取搜索結果的服務是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);即使插入工作正常但在獲取結果期間我收到異常我有一個哈希鍵作為interacting_service 和范圍鍵作為CreatedDate 的表。我正在嘗試通過 GSI 獲取結果 但不知何故它導致了異常 有人可以看到我做錯了什么嗎

您的異常消息說
@DynamoDBIndexHashKey must specify one of HASH GSI name/names
如果您查看類中的所有@DynamoDBIndexHashKey注釋，您會發現它們都設置了一個值，globalSecondaryIndexName除了 上的注釋eventType。如果eventType應該是 GSI 哈希鍵，則需要設置此值。如果eventType不應該是 GSI 的哈希鍵，那么您需要@DynamoDBIndexHashKey從該字段中刪除注釋。
有關使用的更多詳細信息，請參閱javadoc@DynamoDBImdexHashKey。

它必須是這樣的：
@get:DynamoDBIndexHashKey(attributeName = "product", globalSecondaryIndexName = "product-index")
var product: String? = null
將此也添加到數據庫定義中：
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)))
