Insert in DynamoDB Using Java (Guide w/ Code Examples)

Provided by Rafal Wilinski
You can use the PutItemRequest
class offered by the DynamoDB SDK to put new items into DynamoDB.
The following code inserts an item into the table my-table
with three attributes: a primary key attribute ("id") and two other attributes ("attribute1" and "attribute2"). The values for these attributes are specified in the AttributeValue objects
import software.amazon.awssdk.services.dynamodb.DynamoDbClient; import software.amazon.awssdk.services.dynamodb.model.AttributeValue; import software.amazon.awssdk.services.dynamodb.model.AttributeValue.*; import software.amazon.awssdk.services.dynamodb.model.PutItemRequest; import java.util.HashMap; import java.util.Map; public class InsertItem { public static void main(String[] args) { DynamoDbClient ddb = DynamoDbClient.create(); String tableName = "my-table"; Map<String, AttributeValue> item = new HashMap<>(); item.put("id", AttributeValue.builder().s("12345").build()); item.put("attribute1", AttributeValue.builder().s("value1").build()); item.put("attribute2", AttributeValue.builder().s("value2").build()); PutItemRequest request = PutItemRequest.builder() .tableName(tableName) .item(item) .build(); ddb.putItem(request); } }
