Spring boot application.properties 不适用于多个配置文件

Question

我在尝试连接到 aws 中的 dynamodb 时遇到 2 个问题。它在本地工作：

@Configuration
class DynamoDbConfig {
    @Value("${amazon.access.key}")
    private String awsAccessKey;

    @Value("${amazon.access.secret.key}")
    private String awsSecretKey;

    @Value("${amazon.dynamodb.endpoint}")
    private String awsDynamoDBEndPoint;

    @Value("${amazon.dynamodb.region}")
    private String awsDynamoDBRegion;

    @Bean
    public AWSCredentials amazonAWSCredentials() {
        return new BasicAWSCredentials(awsAccessKey, awsSecretKey);
    }

    public AWSCredentialsProvider amazonAWSCredentialsProvider() {
        return new AWSStaticCredentialsProvider(amazonAWSCredentials());
    }

    @Bean
    public DynamoDB dynamoDB() {
        AmazonDynamoDB amazonDynamoDB =  AmazonDynamoDBClientBuilder.standard()
                .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration(awsDynamoDBEndPoint, awsDynamoDBRegion))
                .withCredentials(amazonAWSCredentialsProvider())
                .build();

        return new DynamoDB(amazonDynamoDB);
    }

}

应用程序本地属性

amazon.access.key=key1
amazon.access.secret.key=key2
amazon.dynamodb.endpoint=http://localhost:8000
amazon.dynamodb.region=us-east-1

应用程序-prod.properties

amazon.access.key=${AWS_ACCESS_KEY_ID}
amazon.access.secret.key=${AWS_SECRET_ACCESS_KEY}
amazon.dynamodb.endpoint=dynamodb.us-east-1.amazonaws.com
amazon.dynamodb.region=${AWS_DEFAULT_REGION}

我已经获得了凭据，并且我的 .aws/credentials 看起来不错：

[default]
aws_access_key_id = MyKeyId
aws_secret_access_key = MySecretKey
aws_session_token = blablabla
disney_session_expiration = This is also ok

1 问题）看起来总是使用 application-local.properties 配置文件，如果我在 DynamoDbConfig 类中显示 awsAccessKey 和 awsSecretKey，我会得到 key1 和 key2。我试过这两个命令：

mvn spring-boot:run -Dspring.profiles.active=prod
mvn spring-boot:run -Pprod

2 问题）我将 application-prod.properties 重命名为 application.properties 以使 spring 获取该配置文件，然后我收到以下错误消息：

Could not resolve placeholder 'AWS_SECRET_ACCESS_KEY' in value "${AWS_SECRET_ACCESS_KEY}"

Answer 1

我猜profile 不是问题，没有为以下键设置/定义值

${AWS_ACCESS_KEY_ID}
${AWS_SECRET_ACCESS_KEY}
${AWS_DEFAULT_REGION}
