DynamoDB - 指定两个索引名称@DynamoDbIndexHashkey globalSecondaryIndexName

Question

我有一个DynamoDB表,其中2个GSI具有相同的散列键但不同的范围键.我没有得到如何在@DynamoDBIndexHashKey属性中表示2个索引名称(globalSecondaryIndexName)-

Table
entityid<br/>
placeid<br/>
starttime<br/>
endtime<br/>

GSI 1 - hashkey : placeid, rangekey : starttime<br/>
GSI 2 - hashkey : placeid, rangekey : endtime

@DynamoDBIndexHashKey( attributeName = "placeid" globalSecondaryIndexName= "placeid-starttime-index" )<br>
private String placeid;

如何在此处指定第二个索引名称？

Answer 1

您必须在String数组globalSecondaryIndexNames中指定索引名称:

@DynamoDBIndexHashKey( attributeName = "placeid" globalSecondaryIndexNames={  "placeid-starttime-index","placeid-endtime-index"} )
private String placeid;
