Question

为了向SNS发布消息，我需要承担正确的角色，因此在使用AWS SDK时，我会创建一个像这样的AmazonSNS bean：

@Bean
public AmazonSNS amazonSnsClient(
        @Value("${cloud.aws.credentials.accessKey}") String accessKey,
        @Value("${cloud.aws.credentials.secretKey}") String secretKey,
        @Value("${cloud.aws.role.publisherArn}") String publisherRoleArn
) {
    AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard()
            .withRegion(EU_CENTRAL_1)
            .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(accessKey, secretKey)))
            .build();
    STSAssumeRoleSessionCredentialsProvider credentialsProvider = new STSAssumeRoleSessionCredentialsProvider
            .Builder(publisherRoleArn, SESSION_NAME)
            .withStsClient(stsClient)
            .build();
    return AmazonSNSClientBuilder.standard()
            .withRegion(EU_CENTRAL_1)
            .withCredentials(credentialsProvider)
            .build();
}

我尝试使用Spring Cloud AWS Messaging＆amp; amp;自动配置，但到目前为止，我没有找到有关该主题的任何信息。我的 application.yml 看起来像这样

cloud:   
    aws:
        credentials:
            accessKey: ***
            secretKey: ***
            instanceProfile: true
        region:
            static: eu-central-1

Spring是否支持我并没有设法找到它，或者我应该坚持使用AWS SDK？

看起来没有开箱即用的解决方案。最简单的解决方法是创建自己的AWSCredentialsProvider bean

@Configuration
public class AwsCredentials {

    private static final String SESSION_NAME = "TestConsumer";

    @Bean
    @Primary
    public AWSCredentialsProvider credentialsProvider(
            @Value("${cloud.aws.credentials.accessKey}") String accessKey,
            @Value("${cloud.aws.credentials.secretKey}") String secretKey,
            @Value("${cloud.aws.role}") String role ) {

        AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard()
            .withRegion(EU_CENTRAL_1)
            .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(accessKey, secretKey)))
            .build();
        return new STSAssumeRoleSessionCredentialsProvider
            .Builder(role, SESSION_NAME)
            .withStsClient(stsClient)
            .build();
    }
}

承担Spring Cloud AWS Autoconfiguration的角色
