将AWS s3文件读取为Java代码 [英] Read AWS s3 File to Java code

问题描述

我尝试将AWS s3中的文件读取到我的java代码中：

I tried to read a file from AWS s3 to my java code:

  File file = new File("s3n://mybucket/myfile.txt");
  FileInputStream fileInput = new FileInputStream(file);

然后我收到一个错误：

java.io.FileNotFoundException：s3n：/mybucket/myfile.txt（没有这样的文件或目录）
at java.io.FileInputStream.open（Native Method）
at java.io.FileInputStream。（FileInputStream .java：146）

java.io.FileNotFoundException: s3n:/mybucket/myfile.txt (No such file or directory) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.(FileInputStream.java:146)

有没有办法从AWS s3打开/读取文件？非常感谢！

Is there a way to open/read a file from AWS s3? Thanks a lot!

推荐答案

Java中的'File'类不理解S3存在。 以下是从AWS文档中读取文件的示例：

The 'File' class from Java doesn't understand that S3 exists. Here's an example of reading a file from the AWS documentation:

AmazonS3 s3Client = new AmazonS3Client(new ProfileCredentialsProvider());        
S3Object object = s3Client.getObject(new GetObjectRequest(bucketName, key));
InputStream objectData = object.getObjectContent();
// Process the objectData stream.
objectData.close();
