Amazon S3：如何在Java中展示上传文件的进度

在Java中展示Amazon S3文件上传的进度，你可以使用Amazon S3 SDK提供的`TransferManager`和`ProgressListener`。`TransferManager`类提供了方便的方法来处理并发上传和下载操作，而`ProgressListener`接口允许你监听上传进度。 以下是一个示例代码，展示如何在Java中展示文件上传的进度： ```java AmazonS3 s3Client = AmazonS3ClientBuilder.standard().build(); [string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083) bucketName = "your-bucket-name"; [string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083) filePath = "path/to/file.txt"; // 设置要上传的文件路径 File file = new File(filePath); [string](https://geek.csdn.net/edu/8802d631b97a4a6af1f4d0bbf8527465?dp_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6NDQ0MDg2MiwiZXhwIjoxNzA3MzcxOTM4LCJpYXQiOjE3MDY3NjcxMzgsInVzZXJuYW1lIjoid2VpeGluXzY4NjQ1NjQ1In0.RrTYEnMNYPC7AQdoij4SBb0kKEgHoyvF-bZOG2eGQvc&spm=1055.2569.3001.10083) key = "destin[ati](https://geek.csdn.net/educolumn/150d7073277950db5f09620704e791cf?spm=1055.2569.3001.10083)on/folder/" + file.getName(); // 设置文件在存储桶中的[目标](https://geek.csdn.net/educolumn/06c7a9ffb1969a0ad080048a16f82c4e?spm=1055.2569.3001.10083)路径 TransferManager transferManager = TransferManagerBuilder.standard() .withS3Client(s3Client) .build(); Upload upload = transferManager.upload(bucketName, key, file); // 添加进度监听器 upload.addProgressListener(new ProgressListener() { ```
