springboot实现视频流播放

实现客户端一边拉流一边播放

package com.example.background.handler;

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;

/**
* @description: 视频流和音频流加载设置

@Component
public class VideoHttpRequestHandler 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);
    }
}

控制器

package com.example.background.controller;


import com.example.background.handler.VideoHttpRequestHandler;

@RestController

    String url = "/Users/ming/Desktop/kb.mp4";

    @Autowired

    @ApiOperation(value = "视频流播放", httpMethod = "GET", notes = "dev - Ming")

            if (!StringUtils.isEmpty(mimeType)) {
                response.setContentType(mimeType);
            }
            request.setAttribute(VideoHttpRequestHandler.ATTR_FILE, path);
            videoHttpRequestHandler.handleRequest(request, response);
        } else {
            response.setStatus(HttpServletResponse.SC_NOT_FOUND);
            response.setCharacterEncoding(StandardCharsets.UTF_8.toString());
        }
    }
