环境:springboot2.5.6+jdk1.8
springboot项目中配置了静态资源映射之后就启动项目之后就可以通过地址访问了
@SpringBootApplication public class VideouploadApplication implements WebMvcConfigurer { public static void main(String[] args) { SpringApplication.run(VideouploadApplication.class, args); } /** * 配置静态资源映射 * @param registry */ @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { /* http://localhost:8080/play/1.mp4 下面配置的大概意思就是,只有在url中是以play开头(如:http://localhost:8080/play)+ 文件名 就到文件夹中如(D:\private\javastudaykeshanchu\video\)找到对应的图片或视频,就可以在浏览器地址栏中显示了 */ registry.addResourceHandler("/play/**").addResourceLocations("file:D:\\private\\javastudaykeshanchu\\video\\"); } }
这里使用了sparkmd5,对于相同文件名的视频,加密后的md5是一样的,所以上传会覆盖原来已经存在的md5加密后的文件名。

否则会报如下错误,如果出现如下报错,记得看一下上面的配置是否合理
因为这里我html使用vscode打开的,前后端分离。我并没有将html放在java的static目录下,所以这里有跨域,需要添加@CrossOrigin允许跨域配置
package com.example.controller; import org.springframework.web.bind.annotation.CrossOrigin; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.multipart.MultipartFile; import java.io.IOException; import java.nio.file.Paths; import java.util.HashMap; import java.util.Map; @RestController @RequestMapping("/upload") @CrossOrigin public class UploadVideoController { /** 这里注意了,上面前端使用的是FormDate的形式提交(表单),后端就不能用@RequestBody的形式接受, 应该用@RequestParam的形式接受,如这里的代码所示。这里可以通过参数接受,也可以通过一个Map集合 接受,在map前面(加不加@RequestParam都可以,这里只是说明一下应该用这种形式接收)。当然也可以用一个实体类接受, 同样(加不加@RequestParam都可以,这里只是说明一下应该用这种形式接收) const form = new FormData(); // 这里的data是文件 form.append("data", data); form.append("i", i); form.append("chunks", chunks); // 这里的url是文件名 form.append("filename", part); */ @RequestMapping("/uploadVideo") public Map<String, Object> uploadVideo(int i, MultipartFile data, int chunks, String filename) throws IOException { data.transferTo(Paths.get("D:\\private\\javastudaykeshanchu\\video\\" + filename + ".part" + i)); Map<String, Object> maps = new HashMap<>(); maps.put("filename", filename); // 进度 double jindu = (i * 100.0 / chunks); maps.put("jindu", jindu); return maps; } }
调用uploadVideo() 方法分片上传之后得到的结果
package com.example.controller; import org.springframework.web.bind.annotation.CrossOrigin; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.multipart.MultipartFile; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.util.HashMap; import java.util.Map; @RestController @RequestMapping("/upload") @CrossOrigin public class UploadVideoController { /** * 视频分块上传 * @param i * @param data * @param chunks * @param filename * @return * @throws IOException */ @RequestMapping("/uploadVideo") public Map<String, Object> uploadVideo(int i, MultipartFile data, int chunks, String filename) throws IOException { data.transferTo(Paths.get("D:\\private\\javastudaykeshanchu\\video\\" + filename + ".part" + i)); Map<String, Object> maps = new HashMap<>(); maps.put("filename", filename); // 进度 double jindu = (i * 100.0 / chunks); maps.put("jindu", jindu); return maps; } /** * 视频合并 * @param chunks * @param filename * @return * @throws Exception */ @RequestMapping("/finish") public String finish(int chunks, String filename) throws Exception { FileOutputStream os = null; try { os = new FileOutputStream("D:\\private\\javastudaykeshanchu\\video\\" + filename); for (int i = 1; i <= chunks; i++) { Path path = Paths.get("D:\\private\\javastudaykeshanchu\\video\\" + filename + ".part" + i); // 将临时文件合并为一个文件 Files.copy(path,os); // 删除上传分块的临时文件 Files.delete(path); } } catch (FileNotFoundException e) { e.printStackTrace(); } finally { if(os != null) { os.close(); } } return "http://localhost:8080/play/" + filename; } }
调用了合并的方法之后就可以会删除临时文件合并成完整文件了
通过地址访问就可以了
