SQS로 받은 메시지 Springboot에서 받아보기

2. application.yml

${AWS_ACCESSKEY} 는 intellij 환경변수에 등록해서 사용함

intellij 환경변수  추가는 https://mchch.tistory.com/282 참고

cloud:
  aws:
    credentials:
      access-key: ${AWS_ACCESSKEY}
      secret-key: ${AWS_SECRETKEY}
    region:
      static: ap-northeast-1
      auto: false
    stack:
      auto: false

    sns:
      topic:
        arn: arn:aws:sns:ap-northeast-1:34243243247:MyTopic2

    sqs:
      queue:
        name: MyQueue2
        url: https://sqs.ap-northeast-1.amazonaws.com/34243243247/MyQueue2

3. AWSConfig.java

@Getter
@Configuration
public class AWSConfig {
    @Value("${cloud.aws.credentials.access-key}")
    private String awsAccessKey;

    @Value("${cloud.aws.credentials.secret-key}")
    private String awsSecretKey;

    @Value("${cloud.aws.region.static}")
    private String awsRegion;

    @Value("${cloud.aws.sns.topic.arn}")
    private String snsTopicARN;

    @Bean // SNS Client 세팅
    public SnsClient getSnsClient() {
        return SnsClient.builder()
                .credentialsProvider(
                        getAwsCredentials(this.awsAccessKey, this.awsSecretKey)
                ).region(Region.of(this.awsRegion))
                .build();
    }

	//aws credential 세팅
    public AwsCredentialsProvider getAwsCredentials(String accessKeyID, String secretAccessKey) {
        AwsBasicCredentials awsBasicCredentials = AwsBasicCredentials.create(accessKeyID, secretAccessKey);
        return () -> awsBasicCredentials;
    }

    @Bean // SQS Client 세팅
    public AmazonSQS amazonSQS() {
        AWSCredentials credentials = new BasicAWSCredentials(awsAccessKey, awsSecretKey);
        return AmazonSQSAsyncClientBuilder
                .standard()
                .withCredentials(new AWSStaticCredentialsProvider(credentials))
                .withRegion(awsRegion)
                .build();
    }
}

4. SnsService.java

지정한 topic으로 메세지 발행하는 서비스

@Service
@RequiredArgsConstructor
public class SnsService {
    private final AWSSnsConfig awsConfig;

    public PublishResponse awsSnsPublishTest(Map<String,Object> scriptData) {
        PublishRequest publishRequest = PublishRequest.builder()
                .topicArn(awsConfig.getSnsTopicARN())
                .subject("TEST 제목")
                .message(scriptData.toString())
                .build();

        SnsClient snsClient = awsConfig.getSnsClient();
        PublishResponse publishResponse = snsClient.publish(publishRequest);

        snsClient.close();
        return publishResponse;
    }
}

5. SqsService.java

sns 토픽에서 메세지 가져오는 sqs서비스

@Service
public class SqsService {
    private final QueueMessagingTemplate queueMessagingTemplate;

    @Autowired
    public SqsService(AmazonSQS amazonSqs) {
        this.queueMessagingTemplate = new QueueMessagingTemplate((AmazonSQSAsync) amazonSqs);
    }

    public void getMessage() {
        String rr = queueMessagingTemplate.receiveAndConvert("MyQueue2", String.class);
        System.out.println("queue message :: " + rr );

    }
}

6. SqsListener.java

@Component
public class SqlListener {
    @SqsListener(value = "MyQueue2", deletionPolicy = SqsMessageDeletionPolicy.NEVER)
    public void listen(@Payload String sst, Acknowledgment ack) {
        log.info("{}", sst);
        ack.acknowledge();
    }
}

7. Controller.java 

서비스 호출 controller.

@RestController
@RequiredArgsConstructor
@RequestMapping("api")
public class SnsController {
    private final SnsService snsService;
    private final SqsService sqsService;

	//메세지 발행 메소드
    @PostMapping("/publish")
    public void publish(@RequestBody Map<String, Object> scriptData) {
        PublishResponse pr = snsService.awsSnsPublishTest(scriptData);
        System.out.println(pr);
        //PublishResponse(MessageId=80da361c-4ec9-55f5-9aa8-6a49037995af)

    }

	//메세지 가져오는 메소드
    @GetMapping("/subscribe")
    public void getMessage() {
        sqsService.getMessage();
    }
}
