[S3] 이미지 링크 자꾸 다운로드 됨

import java.io.IOException;

public class AmazonS3Manager{

    private final AmazonS3 amazonS3;

    private final AmazonConfig amazonConfig;

    private final UuidRepository uuidRepository;

    public String generateMembersKeyName(Uuid uuid) {
        return amazonConfig.getMemebersPath() + '/' + uuid.getUuid();
    }

    public void deleteFile(String keyName) {
        amazonS3.deleteObject(new DeleteObjectRequest(amazonConfig.getBucket(), keyName));
    }


    public String uploadFile(String keyName, MultipartFile file){
        ObjectMetadata metadata = new ObjectMetadata();
        metadata.setContentLength(file.getSize());
        try {
            amazonS3.putObject(new PutObjectRequest(amazonConfig.getBucket(), keyName, file.getInputStream(), metadata));
        } catch (IOException e){
            log.error("error at AmazonS3Manager uploadFile : {}", (Object) e.getStackTrace());
        }

        return amazonS3.getUrl(amazonConfig.getBucket(), keyName).toString();
    }
}

 

자꾸 생성된 링크가 다운로드 되었다.

 

알고보니 코텐츠 타입 설정을 하지 않았다.

 

 metadata.setContentType(file.getContentType());

 

 

이 코드를 다음과 같이 추가하면 된다.

 

import java.io.IOException;

@Slf4j
@Component

public class AmazonS3Manager{

    private final AmazonS3 amazonS3;

    private final AmazonConfig amazonConfig;

    private final UuidRepository uuidRepository;

    public String generateMembersKeyName(Uuid uuid) {
        return amazonConfig.getMemebersPath() + '/' + uuid.getUuid();
    }

    public void deleteFile(String keyName) {
        amazonS3.deleteObject(new DeleteObjectRequest(amazonConfig.getBucket(), keyName));
    }


    public String uploadFile(String keyName, MultipartFile file){
        ObjectMetadata metadata = new ObjectMetadata();
        ////////// 여기에 추가 ///////////
        metadata.setContentType(file.getContentType());
        /////////////////////////////////
        metadata.setContentLength(file.getSize());
        try {
            amazonS3.putObject(new PutObjectRequest(amazonConfig.getBucket(), keyName, file.getInputStream(), metadata));
        } catch (IOException e){
            log.error("error at AmazonS3Manager uploadFile : {}", (Object) e.getStackTrace());
        }

        return amazonS3.getUrl(amazonConfig.getBucket(), keyName).toString();
    }
}
