AWS DynamoDB

AWS DynamoDB

1.配置AWS
$ aws configure
AWS Access Key ID [None]: xxxxx
AWS Secret Access Key [None]: xxxxxxx
Default region name [None]: us-west-2
Default output format [None]: json

aws configure 不起作用就修改 C:UsersAdministrator.awscredentials

$ aws configure set aws_access_key_id aws_access_key_id
$ aws configure set aws_secret_access_key aws_secret_access_key/EOcyx0Ll
$ aws configure set default.region us-west-2
$ aws configure set default.ca_bundle /path/to/ca-bundle.pem
$ aws configure set region us-west-1 --profile testing
$ aws configure set profile.testing2.region eu-west-1
$ aws configure set preview.cloudsearch true

2.启动DynamoDB local
d:
cd D:dbDynamoDBdynamodb_local_latest
java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

3.查询
aws dynamodb list-tables --endpoint-url http://localhost:8000 --output json

aws dynamodb --endpoint-url http://localhost:8000 --output json put-item --table-name t02_ATD_INFO --item "{"deviceId":{"S":"ABCDEFG123456789"},"shardId":{"S":"0001"}}" --return-consumed-capacity TOTAL

json参数用"包围 内容中的"要转义 "

调用
DynamoDBMapper mapper = null;

// 1.エンドポイント設定
EndpointConfiguration endpointConfiguration = new EndpointConfiguration(
props.getEndpoint(), commonProps.getRegion());

// 2.認証設定
AWSCredentialsProvider credentialsProvider = new DefaultAWSCredentialsProviderChain();

// 3.コンフィグ設定
ClientConfiguration config = new ClientConfiguration();
new RelaxedDataBinder(config)
.bind(new MutablePropertyValues(props.getConfig()));

// 4.クライアント生成
AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard()
.withEndpointConfiguration(endpointConfiguration)
.withCredentials(credentialsProvider)
.withClientConfiguration(config).build();

// 5.マッパー生成
DynamoDBMapperConfig mapperConfig = DynamoDBMapperConfig.builder()
.withTableNameOverride(TableNameOverride
.withTableNamePrefix(commonProps.getEnvId() + "_"))
.build();
mapper = new DynamoDBMapper(client, mapperConfig);
// CreateTableRequest req = mapper.generateCreateTableRequest(MailInfo.class);
// req.setProvisionedThroughput(new ProvisionedThroughput(5L, 5L));
// client.createTable(req);

// insert
String mailId = "11";
MailInfo test = new MailInfo();
test.setMailId(mailId);
test.setMailBody("testtesttest");
mapper.save(test);

// select
MailInfo dynamo = mapper.load(MailInfo.class, mailId);
