Spring boot 如何使用SpringBoot Rest API Apache CXF实现下载大型zip文件（1-2GB）？

如何使用SpringBoot Rest API Apache CXF实现下载大型zip文件（1-2GB）

我尝试过使用输出流，但没有成功

    InputStream inputStream = new FileInputStream(new File(file));

        return new StreamingResponseBody() {

            @Override
            public void writeTo(OutputStream outputStream)
                    throws IOException {
                int nRead;
                byte[] data = new byte[1024];
                while ((nRead = inputStream.read(data, 0, data.length)) != -1) {
                    System.out.println("Writing some bytes..");
                    outputStream.write(data, 0, nRead);
                }
                inputStream.close();
            }

        };

我尝试了下面的代码，它可以下载500MB的文件，但它也可以用于1-2GB的文件：

try {
            String link = "https://s.basketbuild.com/uploads/devs/dianlujitao/oneplus3/cm13/cm-13.0-20160621-UNOFFICIAL-oneplus3.zip";
            URL url = new URL(link);

            System.out.println("Started reading the zip");

            File dir = new File("C:\\Softwares\\testdownload");
            if (!dir.exists())
                dir.mkdirs();

            String fileBaseName = "TestDownload";
            String fileExtension = "zip";
            System.out.println("Name: " + fileBaseName + '.' + fileExtension);
            File outputFile = new File(dir, fileBaseName + '.' + fileExtension);

            if (!outputFile.exists()) {

                outputFile.createNewFile();
            }

            InputStream inputStream = new BufferedInputStream(url.openStream());
            OutputStream byteArrayOutputStream = new BufferedOutputStream(new FileOutputStream(outputFile));
            int n = 0;
            byte[] buf = new byte[1024];
            long duration = System.currentTimeMillis();
            while ((n = inputStream.read(buf)) != -1) {
                byteArrayOutputStream.write(buf, 0, n);
            }
            duration = System.currentTimeMillis() - duration;
            System.out.println("Finish in " + duration + "ms");

            inputStream.close();

            // release outputstream
            byteArrayOutputStream.close();
            System.out.println("Your download has been finished");

        } catch (MalformedURLException e) {
            e.printStackTrace();
            System.out.println("Something unexpected has happened!");
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("Something unexpected has happened!");
        }

在您的示例中，您使用了URL，但我尝试从服务器目录或文件系统中读取。如何根据需要进行修改？
