S3设置公共可读

1.引入jar

        
            software.amazon.awssdk
            s3
            2.15.20
        

2. 设置可读属性

    private static S3Client s3;
    @Autowired
    S3Config s3Config;
    
    public String upload(MultipartFile file) throws IOException {
        String fileKey = null;
        fileKey = DateUtil.format(new Date(), DatePattern.PURE_DATE_PATTERN) + "/" + IdUtil.simpleUUID()+"."+file.getOriginalFilename();
        // 设置公共可读属性
        PutObjectRequest objectRequest = PutObjectRequest.builder().bucket(s3Config.getBucketName()).key(fileKey).acl(ObjectCannedACL.PUBLIC_READ).build();
        s3.putObject(objectRequest, RequestBody.fromBytes(file.getBytes()));

        GetUrlRequest request = GetUrlRequest.builder().bucket(s3Config.getBucketName()).key(fileKey).build();
        s3.utilities().getUrl(request);
        return fileKey;
    }

    
    @Component
    @ConfigurationProperties(prefix="aws.s3")
    @Data
    public class S3Config {
        private String accessKey;

        private String secretKey;

        private String bucketName;

        private String region;
    }
