如何标记一定S3文件通过Web服务API曝光。

Answer 1:

使用方法setCannedAcl(CannedAccessControlList.PublicRead)改变访问控制权限。 详细内容请阅读Java文档在这里

示例代码：

BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(ACCESS_KEY,SECRET_KEY);   
AmazonS3 s3 = new AmazonS3Client(basicAWSCredentials);

PutObjectRequest putObj = new PutObjectRequest(bucketName, objectKey, fileToUpload);

// making the object Public
putObj.setCannedAcl(CannedAccessControlList.PublicRead);

s3.putObject(putObj);
