Today, I will talk to you about how to write the code for real-time SpringBoot static video playback, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.
Problem description
Spring Boot API defines the GET request API and returns the video stream. The front end loads and plays the video through the tag, and the effect is that the entire video resource must be loaded into the browser before it can be played, and the default progress bar of the tag cannot control the video playback. In the end, the desired effect is that the video stream is loaded and played at the same time, and the player control is used normally.
Solution method
Spring Framework file request processing
Import org.springframework.core.io.FileSystemResource;import org.springframework.core.io.Resource;import org.springframework.stereotype.Component;import org.springframework.web.servlet.resource.ResourceHttpRequestHandler;import javax.servlet.http.HttpServletRequest;import java.nio.file.Path;@Componentpublic class NonStaticResourceHttpRequestHandler extends ResourceHttpRequestHandler {public final static String ATTR_FILE = "NON-STATIC-FILE"; @ Override protected Resource getResource (HttpServletRequest request) {final Path filePath = (Path) request.getAttribute (ATTR_FILE); return new FileSystemResource (filePath);}}
Controller layer
@ RestController@AllArgsConstructorpublic class FileRestController {private final NonStaticResourceHttpRequestHandler nonStaticResourceHttpRequestHandler; / * Preview video file. Support byte-range request * / @ GetMapping ("/ video") public void videoPreview (HttpServletRequest request, HttpServletResponse response) throws Exception {String path = request.getParameter ("path"); Path filePath = Paths.get (path); if (Files.exists (filePath)) {String mimeType = Files.probeContentType (filePath); if (! StringUtils.isEmpty (mimeType)) {response.setContentType (mimeType) } request.setAttribute (NonStaticResourceHttpRequestHandler.ATTR_FILE, filePath); nonStaticResourceHttpRequestHandler.handleRequest (request, response);} else {response.setStatus (HttpServletResponse.SC_NOT_FOUND); response.setCharacterEncoding (StandardCharsets.UTF_8.toString ());}
After reading the above, do you have any further understanding of how to write the code for real-time SpringBoot still video playback? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
