我正在学习DynamoDB，所以我尝试使用Sping Boot 和DynamoDB做一个基本的项目。我检查了这些链接来成功运行这个应用程序，但失败了：（

    对于数据库设置，我使用了Docker。下面是我的组合文件：
version: '3.7'

services:
  localstack:
    container_name: localstack
    image: localstack/localstack:latest
    environment:
      - DEBUG=1
      - USE_SSL=0
      - AWS_CBOR_DISABLE=1
      - DOCKER_HOST=unix:///var/run/docker.sock
      - HOSTNAME=localstack
      - SERVICES=dynamodb
      - AWS_DEFAULT_REGION=us-east-1
    ports:
      - '4566-4583:4566-4583'
    volumes:
      - ${TEMPDIR:-/tmp/localstack}:/var/lib/localstack
      - /var/run/docker.sock:/var/run/docker.sock
      - ./script/init-dynamodb.sh:/docker-entrypoint-initaws.d/init-dynamodb.sh

创建表的脚本如下所示：

#!/bin/bash

# -- > Create DynamoDb Table
echo Creating  DynamoDb \'ItemInfo\' table ...
echo $(awslocal dynamodb create-table --cli-input-json '{
    "TableName":"ItemInfo",
    "KeySchema":
      [
        {"AttributeName":"id","KeyType":"HASH"}
      ],
      "AttributeDefinitions":
        [
          {"AttributeName":"id","AttributeType":"S"}
        ],
        "BillingMode":"PAY_PER_REQUEST"
  }'
)

echo Creating  DynamoDb \'Music\' table ...

echo $(awslocal dynamodb create-table --cli-input-json '{
    "TableName":"Music",
    "KeySchema":
      [
        {"AttributeName":"Artist","KeyType":"HASH"},
        {"AttributeName":"SongTitle","KeyType":"RANGE"}
      ],
      "AttributeDefinitions":
        [
          {"AttributeName":"Artist","AttributeType":"S"},
          {"AttributeName":"SongTitle","AttributeType":"S"}
        ],
      "ProvisionedThroughput":{
        "WriteCapacityUnits": 5,
        "ReadCapacityUnits": 5
      },
      "TableClass": "STANDARD"
  }'
)

# --> List DynamoDb Tables
echo Listing tables ...
echo $(awslocal dynamodb list-tables)

因此，运行后：

sudo docker compose up -d

当我执行这个命令时：

aws --endpoint-url=http://localhost:4566 --region=us-east-1  dynamodb describe-table --table-name Music

我得到这个：

{
    "Table": {
        "AttributeDefinitions": [
            {
                "AttributeName": "Artist",
                "AttributeType": "S"
            },
            {
                "AttributeName": "SongTitle",
                "AttributeType": "S"
            }
        ],
        "TableName": "Music",
        "KeySchema": [
            {
                "AttributeName": "Artist",
                "KeyType": "HASH"
            },
            {
                "AttributeName": "SongTitle",
                "KeyType": "RANGE"
            }
        ],
        "TableStatus": "ACTIVE",
        "CreationDateTime": "2023-03-07T14:17:46.287000+06:00",
        "ProvisionedThroughput": {
            "LastIncreaseDateTime": "1970-01-01T06:00:00+06:00",
            "LastDecreaseDateTime": "1970-01-01T06:00:00+06:00",
            "NumberOfDecreasesToday": 0,
            "ReadCapacityUnits": 5,
            "WriteCapacityUnits": 5
        },
        "TableSizeBytes": 0,
        "ItemCount": 0,
        "TableArn": "arn:aws:dynamodb:us-east-1:000000000000:table/Music",
        "TableId": "bcce1ab3-8f0c-4b8f-9d55-6c69ec1ef2ad",
        "Replicas": [],
        "TableClassSummary": {
            "TableClass": "STANDARD"
        }
    }
}

所以我相信创建表是可以的。现在我展示（DynamoDB Table）音乐类：

@DynamoDBTable(tableName = "Music")
public class Music implements Serializable {
    @Id
    private MusicId musicId;

    public Music() {}

    public Music(MusicId musicId) {
        this.musicId = musicId;
    }

    public MusicId getMusicId() {
        return musicId;
    }

    public void setMusicId(MusicId musicId) {
        this.musicId = musicId;
    }

    @DynamoDBHashKey(attributeName = "Artist")
    public String getArtist() {
        return musicId != null ? musicId.getArtist() : null;
    }
    
    public void setArtist(String artist) {
        if (musicId == null)
            musicId = new MusicId();
        musicId.setArtist(artist);
    }

    @DynamoDBRangeKey(attributeName = "SongTitle")
    public String getSongTitle() {
        return musicId != null ? musicId.getSongTitle() : null;
    }

    public void setSongTitle(String songTitle) {
        if (musicId == null)
            musicId = new MusicId();
        musicId.setSongTitle(songTitle);
    }
}

下面是MusicId（DynamoDB文档）类：

@DynamoDBDocument
public class MusicId implements Serializable {
    private static final long serialVersionUID = 100L;

    public MusicId() {

    }

    public MusicId(String artist, String songTitle) {
        this.artist = artist;
        this.songTitle = songTitle;
    }

    private String artist;
    private String songTitle;

    @DynamoDBHashKey(attributeName = "Artist")
    public String getArtist() {
        return artist;
    }

    public void setArtist(String artist) {
        this.artist = artist;
    }

    @DynamoDBRangeKey(attributeName = "SongTitle")
    public String getSongTitle() {
        return songTitle;
    }

    public void setSongTitle(String songTitle) {
        this.songTitle = songTitle;
    }
}

这里是音乐库：

@EnableScan
public interface MusicRepository extends CrudRepository<Music, MusicId> {
}

下面是实现DynamoDbService的DynamoDbServiceImpl：

@Service
public class DynamoDbServiceImpl implements DynamoDbService {
    private final ItemInfoRepository itemInfoRepository;
    private final MusicRepository musicRepository;

    @Autowired
    public DynamoDbServiceImpl(ItemInfoRepository itemInfoRepository, MusicRepository musicRepository) {
        this.itemInfoRepository = itemInfoRepository;
        this.musicRepository = musicRepository;
    }

    @Override
    public void saveItem(ItemInfoDto dto) {
        ItemInfo itemInfo = new ItemInfo();
        itemInfo.setItemName(dto.getItemName());
        itemInfo.setItemUrl(dto.getItemUrl());
        itemInfoRepository.save(itemInfo);
    }

    @Override
    public void saveMusic(MusicDto dto) {
        Music music = new Music();
        music.setArtist(dto.getArtist());
        musicRepository.save(music);
    }
}

下面是要配置的AwsDynamoDbConfig：

@Getter
@Setter
@Configuration
@EnableDynamoDBRepositories(basePackages = "com.mukit09.dynamodblearning.repository")
public class AwsDynamoDbConfig {
    @Value("${config.aws.region}")
    private String region;
    @Value("${config.aws.dynamodb.url}")
    private String dynamoDbEndpointUrl;
    @Value("${config.aws.dynamodb.access-key}")
    private String accessKey;
    @Value("${config.aws.dynamodb.secret-key}")
    private String secretKey;

    @Bean(name = "amazonDynamoDB")
    public AmazonDynamoDB amazonDynamoDB() {
        return AmazonDynamoDBClientBuilder.standard()
                .withCredentials(getCredentialsProvider())
                .withEndpointConfiguration(getEndpointConfiguration(dynamoDbEndpointUrl))
                .build();
    }

    private EndpointConfiguration getEndpointConfiguration(String url) {
        return new EndpointConfiguration(url, region);
    }

    private AWSStaticCredentialsProvider getCredentialsProvider() {
        return new AWSStaticCredentialsProvider(getBasicAWSCredentials());
    }

    private BasicAWSCredentials getBasicAWSCredentials() {
        return new BasicAWSCredentials(accessKey, secretKey);
    }
}

这些是www.example.com上的内容application.properties:

#dynamoDB
config.aws.region=us-east-1
config.aws.dynamodb.url=http://127.0.0.1:4566
config.aws.dynamodb.access-key=localstack
config.aws.dynamodb.secret-key=localstack

#log
logging.file.name=debug.log
logging.level.root= debug

这是我的gradle文件（build.gradle）：

plugins {
    id 'java'
    id 'org.springframework.boot' version '2.7.9'
    id 'io.spring.dependency-management' version '1.0.15.RELEASE'
}

group = 'com.mukit09'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'com.github.derjust:spring-data-dynamodb:5.1.0'
    implementation 'com.amazonaws:aws-java-sdk-dynamodb:1.12.420'

    compileOnly 'org.projectlombok:lombok'

    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
    annotationProcessor 'org.projectlombok:lombok'
}

tasks.named('test') {
    useJUnitPlatform()
}

当我尝试运行此应用程序时，它无法保留此日志：
