简易局域网视频服务器
2 原理 主要是利用了html中的vedio标签，在tomcat服务器下播放指定文件夹中的mp4视频。 2.1 源码展示 2.1.1 获得视频列表的工具类
import java.util.ArrayList;
public class file {
private static String path = "E:/apache-tomcat-7.0.62/apache-tomcat-7.0.62/webapps/vedio";
/**
*
* @param dir
* @throws Exception
*/
static void showAllFiles(File dir) throws Exception {
File[] fs = dir.listFiles();
for (int i = 0; i < fs.length; i++) {
System.out.println(fs[i].getName());
if (fs[i].isDirectory()) {
try {
showAllFiles(fs[i]);
} catch (Exception e) {
}
}
}
}
public static ArrayList<String> getallfiles() throws Exception {
File dir = new File(path);
File[] fs = dir.listFiles();
ArrayList<String> filelist = new ArrayList<String>();
for (int i = 0; i < fs.length; i++) {
System.out.println(fs[i].getName());
if (fs[i].isDirectory()) {
try {
showAllFiles(fs[i]);
} catch (Exception e) {
}
} else {
filelist.add(fs[i].getName());
}
}
return filelist;
}
public static void main(String[] args) {
File root = new File(path);
try {
showAllFiles(root);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}2.1.2 播放视频的jsp代码
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
String vediopath = (String) request.getAttribute("vediopath");
%>

type=video/mp4; codecs="avc1.42E01E, mp4a.40.2"></source> </video>
</body>
</html>3 项目下载
4 使用 4.1 安装tomcat7.0以上版本
4.2 部署项目
4.3 在webapp目录下面建立vedio目录用来存放视频
5 局限
只能播mp4，其它的没有试过，有可能能播，但是mp4效果是最好的。推荐用狸窝全能视频转换器转成mp4。
