![]() Upload some files: Upload a file with size larger than max file size (2MB): Check files table in Database: Retrieve list of Files’ information: Now you can download any file from one of the paths above. If (responseCode = HttpURLConnection.HTTP_OK) This program downloads the file and saves it into the directory E:/Download. Run Spring Boot application with command: mvn spring-boot:run. Int responseCode = httpConn.getResponseCode() HttpURLConnection httpConn = (HttpURLConnection) url.openConnection() Public static void downloadFile(String fileURL, String saveDir) ![]() * saveDir path of the directory to save the file * fileURL HTTP URL of the file to be downloaded Private static final int BUFFER_SIZE = 4096 * A utility that downloads a file from a URL. Close the input stream, the output stream and the connection.įor the purpose of reusability, we create a utility class as follows: package.Repeatedly read array of bytes from the input stream and write them to the output stream, until the input stream is empty.Create an output stream to save file to disk.Open the input stream of the opened connection.Open connection on the URL object – which would return an HttpURLConnection object if the URL is an HTTP URL.An indirect link which does not contain the real file name, for example:.A direct link which contains the real file name at the end, for example:.In this post, I will guide you how to write Java code to download files from web server programmatically.You know, in Java, we can use the classes URL and HttpURLConnection in the package to programmatically download a file from a given URL by following these steps:
