How to Implement HTTP byte-range requests in Spring MVC

http byte range request example
spring boot 206 partial content
spring mvc display image in jsp example
spring boot return image
retrieve image from database using spring mvc
spring mvc video streaming
spring mediatype svg
accept-ranges bytes

I have the problem with video rewind on my site.

I figure out that problem with http headers.

My current controller method which returns video:

@RequestMapping(method = RequestMethod.GET, value = "/testVideo")
@ResponseBody
public FileSystemResource testVideo(Principal principal) throws IOException {
   return new FileSystemResource(new File("D:\\oceans.mp4"));
}

How to rewrite following code with byte-range supporting?

P.S.

I have seen following example http://balusc.blogspot.in/2009/02/fileservlet-supporting-resume-and.html

But this code looks hard for me and I cannot understand it. I hope that in spring mvc exists way simpler.

The request for support for http byte-range was open at the time of this answer but is fixed in Spring 4.2.RC1. Check jira SPR-10805 or, the PR here.

But based on the code that you linked in your question, Davin Kevin built a solution that could work for your request.

Code for MultipartFileSender:

Implementing HTTP byte-range requests in Spring MVC, The blog-post talks about supporting byte-range or part-range requests as received from the client browser or any HTTP-based client who wishes to send such requests. Next, you just need to define the above view class to be a Spring bean and use it in Spring MVC's ModelAndView object.

If you want to avoid MimeTypeUtils, you can use Files.probeContentType(Path path). That will use the default implementation of the system.

Depending on what you're trying to achieve, it may make sense for you to map the request by to the container's default servlet.

I.e., during initialization:

ServletContext container = ...

ServletRegistration servletRegistration = container.getServletRegistration("default");

The answer of Leandro worked perfectly for me. I only changed the InputStream with a RandomAccessFile, it is performing better to access a random point inside a file.

woww, The answer of Leandro so briliant. just create service file follow him and use in controller. here my after follow his guidelines

@RequestMapping(value = [(SKConstant.URL_PROJECT_API + "/video/{token}")], method = arrayOf(RequestMethod.GET)
fun getVideo(@PathVariable("token") token: String, response: HttpServletResponse, request: HttpServletRequest): Any?{
         val file = baseService.getByToken(token)
         if(file != null) {
           return MultipartFileSender.fromFile(File(fileService.getUploadFileRealPath(file.uniqueName!!)))
                              .with(request)
                              .with(response)

Spring MVC ResponseEntity enables control not only over the body of the HTTP Response but also the header and the respose status code. Following this approach, you need to define the return type of the method as ResponseEntity<byte[]> and create returning ResponseEntity object in the method body.

Building a video service using Spring Framework, One of the domains to apply this new framework is data streaming, It comes from the Range Requests specification and asks the server curl -s -o /dev/null -​H "Range: bytes=0-" -D - http://localhost:8080/videos/fish.mp4/full. Generally speaking, it is a simple http GET request. The only additional data that matters is the Range header. It comes from the Range Requests specification and asks the server for a specific part of the file. The header in the previous request means that the client expects data from position 0 in a byte representation of file till the end.

Beans whose lifecycle is scoped to the current HTTP request or HTTP Session. This is not a specific feature of Spring MVC itself, but rather of the WebApplicationContext container(s) that Spring MVC uses. These bean scopes are described in Section 5.5.4, “Request, session, and global session scopes”

HttpRange (Spring Framework 5.2.6.RELEASE API), Represents an HTTP (byte) range for use with the HTTP "Range" header. Since: 4.2 firstBytePos). Create an HttpRange from the given position to the end. In this Spring MVC tutorial, you will learn how to use @PutMapping annotation in your RESTful Web Services application to be able to accept HTTP Put request containing a Request Body with JSON or XML payload, so that you can perform let’s say an update user details operation.

Comments
  • I cannot find jat with following class: lan.dk.podcastserver.utils.MimeTypeUtils
  • Removed that import and changed to have the mimetype fixed to "video/mp4", but the entire project is posted at github: github.com/davinkevin/Podcast-Server
  • Now it is SO style. question - answer wihout redundant context. I am sure it will be useful for future googlers.
  • Is there any way to change the default implementation of the Static resource resolver of spring(older version than 4.2RC1), with a controller that can support http range, for download resume ?
  • This has a bug in the multipart branch. Skipping the stream by the full amount every time won't read the expected bytes unless the stream is marked / reset for each read. The better alternative is (of course) to adjust the offset according to the last read position.
  • Never convert InputStream to byte[] in this context. You'll have serious memory issues.
  • Won't support http-byte-range
