如何使用 Java 读取 AWS S3 文件? [英] How can I read an AWS S3 File with Java?

问题描述

我尝试从 AWS S3 读取文件到我的 java 代码:

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);

然后我得到一个错误:

java.io.FileNotFoundException: s3n:/mybucket/myfile.txt (No such file or directory)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(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"类不了解 S3 的存在.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();
