在上面的代码中,我们首先定义了一个FileDownloader类,其中包含了一个静态方法downloadFile。该方法接收两个参数:fileURL表示要下载的文件的URL地址,saveDir表示要保存到本地的文件路径。在downloadFile方法中,我们首先创建了一个URL对象,然后打开了一个输入流(InputStream)和一个输出流(OutputStream),并创建了一个缓冲区(...
In this Jersey file stream or download example, we will learn to write a Jersey rest api which will be able to stream file using StreamingOutput class.
在Java中可以通过使用URLConnection类来实现文件下载功能。以下是一个简单的示例代码: import java.io.FileOutputStream; import java.io.InputStream; import java.net.URL; import java.net.URLConnection; public class FileDownload { public static void main(String[] args) { String fileUrl = "http://exa...
String fileUrl="https://example.com/sample.txt";// 远程文件的URLURLurl=newURL(fileUrl);URLConnection connection=url.openConnection(); 步骤3:获取输入流 通过打开的连接,您可以获取一个输入流,用于从远程服务器读取文件的内容。 代码语言:javascript ...
file.transferTo(saveFile);// 存储文件到本地的磁盘里面去// 返回文件的链接,这个链接就是文件的下载地址,这个下载地址就是我的后台提供出来的// String url = "http://" + ip + ":" + port + "/file/download/" + originalFilename;String url ="http://"+ ip +":"+ port +"/file/download...
io.File; import java.io.IOException; import java.net.URLEncoder; @RestController public class FileDownloadController { @GetMapping("/download") public ResponseEntity<byte[]> downloadFile() throws IOException { String fileName = "example.txt"; // 要下载的文件名 File file = new File("/path/to...
@GetMapping("/download") public void downloadFile(HttpServletResponse response) { File file = new File("/path/to/file/example.pdf"); response.setContentType("application/pdf"); response.setHeader("Content-Disposition", "attachment; filename=" + file.getName()); try (FileInputStream fis = ...
