DynomaDB Local使用（二）

Example Gradle Java project for using AWS DynamoDB for local testing
参照 DynamoDB (下载版本) 和 Apache Maven
资源 GitHub

环境

AWS SDK for Java 2.4.14
Spring Boot 2.1.3.RELEASE

Spring Boot Initializer 新建工程

参照 Spring Initializr Java Support

依赖

添加

dependencies {
   compile 'software.amazon.awssdk:dynamodb'
   ............
   ............
}   
dependencyManagement {
    imports {
		// AWS SDK for Java 1.X
		//mavenBom 'com.amazonaws:aws-java-sdk-bom:1.11.97'
		// AWS SDK for Java 2.X
        mavenBom 'software.amazon.awssdk:bom:2.4.14'
    }
}

基本用法

DynamoDbClient的客户端生成

@Bean
    public DynamoDbClient amazonDynamoDBClient() throws URISyntaxException {
        log.info("amazonDynamoDBClient Start.");
        DynamoDbClient client = null;
        log.info("amazonDynamoDBClient.getEndpoint:{};",awsDynamodbConfig.getEndpoint());   
        if(!awsDynamodbConfig.getEndpoint().isEmpty()) {
            URI uri = new URI(awsDynamodbConfig.getEndpoint());
            log.info("URI:{}",uri);
            client = DynamoDbClient.builder()
                        .credentialsProvider(StaticCredentialsProvider.create(
                            AwsBasicCredentials.create("test","test")))
                        .region(Region.of(awsCommonConfig.getRegion()))
                        .endpointOverride(new URI(awsDynamodbConfig.getEndpoint()))
                        .build();
        } else {
            client = DynamoDbClient.builder()
                        .region(Region.of(awsCommonConfig.getRegion()))
                        .build();
        }
        return client;              
    }

通过客户端请求各API

ListTablesResponse response = dynamoDBClient.listTables(ListTablesRequest.builder().limit(5).build());
            names = response.tableNames();

测试

1. 参照 DynamoDB Local使用（一）
   启动本地DynamoDB服务器
2. 做成上面的开发工程
   通过 localhost:9999 访问，admin / 123
