[AWS] SpringBoot 에서 SQS 사용하기 (send, receive)
- AWS SQS 활용하기
- 참고사이트
직접 Restful API 적용한 내용을 참고하고 싶으면 여기 와 여기에서 확인 가능합니다.
시작하기 전에 앞서
여러 블로그을 참고하여 진행하다보니 아래와 같은 에러가 발생했습니다.
- com.amazonaws.SdkClientException: Unable to load AWS credentials from any provider in the chain
- javax.jms.JMSException: AmazonClientException: getQueueUrl.
- java.lang.IllegalArgumentException: profile file cannot be null
위 에러는 모두 SQS 커넥션 설정이 무언가 제대로 되지 않았다는 내용이며, 아마 아래와 같은 방법으로 커넥션을 생성 할 때 발생했을겁니다.

.withCredentials(new ProfileCredentialsProvider("username"))
.withCredentials(DefaultAWSCredentialsProviderChain.getInstance())
.withCredentials(new DefaultAWSCredentialsProviderChain())
위 오류를 해결을 원한다면 Access Key 발급 후 아래 내용대로 차근차근 진행하면 되니 같은 오류 발생하신 분들 모두 화이팅입니다.

마치며
위 내용을 테스트 해보고 싶다면, 본인의 Access Key 와 Secret, queueName 을 본인의 값으로 입력 하고 호출하면 됩니다.
sendMessage 메소드를 호출 시 아래 이미지와 같이 AWS Console의 대기열 큐에서 확인 가능합니다.
사용 가능한 메시지 부분에 1이 표시되어 있고, 우측에 있는 메세지 폴링
을 누르면 메세지를 가져올 수 있습니다. 가지고 온 메세지를 선택하면 아래와 같이 메세지 확인이 가능합니다.
receive 메소드를 호출하면 아래 메세지를 직접 받아 볼 수 있습니다.
