1、主要是通过ResourceHttpRequestHandler类来实现，ResourceHttpRequestHandler本身支持分片加载，前端在请求头中携带Range: bytes = 0-5001，就可以从后台自动截取对应大小视频内容。

第一步，先自定义实现一个ResourceHttpRequestHandler。代码如下：

package com.tec666.moviebar.config; 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; /** * @author longge93 */ @Component public class NonStaticResourceHttpRequestHandler extends ResourceHttpRequestHandler { public final static String ATTR_FILE = "NON-STATIC-FILE"; @Override protected Resource getResource(HttpServletRequest request) { String filePath = (String) request.getAttribute(ATTR_FILE); return new FileSystemResource(filePath); } }

第二步，在视频播放controller中，把本地文件路径传入ResourceHttpRequestHandler。代码如下：

@Controller @RequestMapping(value = "/api/baseResource") public class BaseSourceApiController { @Autowired private NonStaticResourceHttpRequestHandler nonStaticResourceHttpRequestHandler; private final Logger logger = LoggerFactory.getLogger(this.getClass()); @RequestMapping(value = "/video", method = RequestMethod.GET) public void video( HttpServletRequest request, HttpServletResponse response ) { try { String path = "D:/abc.mp4"; File file = new File(path); if (file.exists()) { request.setAttribute(NonStaticResourceHttpRequestHandler.ATTR_FILE, path); nonStaticResourceHttpRequestHandler.handleRequest(request, response); } else { response.setStatus(HttpServletResponse.SC_NOT_FOUND); response.setCharacterEncoding(StandardCharsets.UTF_8.toString()); } } catch (Exception e) { } } }
