这是通过SpringMVC框架实现的一个前端视频或图片的显示:
JAVA代码,后台提供IO流,输出到前端页面
@RequestMapping("stream")
public void getStreamData(HttpServletResponse response) {
File file=new File("C:\\avi_vedio\\test.MP4");
ServletOutputStream out=null;
try {
FileInputStream instream=new FileInputStream(file);
byte[] b=new byte[1024];
int length=0;
BufferedInputStream buf=new BufferedInputStream(instream);
out=response.getOutputStream();
BufferedOutputStream bot=new BufferedOutputStream(out);
while((length=buf.read(b))!=-1) {
bot.write(b,0, b.length);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
前端提供一个存放图片(img)或者视频(video)的DIV
<body>
<video width="320" height="240" controls>
<!-- src属性里写java代码提供服务的地址 -->
<source src="http://localhost:8080/sjsc/wechatapp/violationitem/stream"
type="video/mp4">
</video>
</body>
