JavaWeb向浏览器返回一个音频流

浏览器直接播放音频文件,1是直接访问一个html的音频文件,,2 是返回一个Java音频流给浏览器解析.

下面实现一个java的wav文件音频流,可以直接播放音频文件

 import javax.servlet.http.HttpServletResponse;

 public class Music extends HttpServlet {

     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
         // 设置响应内容类型

          response.setHeader("Content-type", "text/html; charset=UTF-8");
          request.setCharacterEncoding("UTF-8");//解决乱码
          response.setContentType("text/html;charset=UTF-8");//解决乱码
          String sentences=request.getParameter("text");
         try {
             sayPlay(sentences,request,response);
         }catch (Exception e){
             System.out.printf(e.getMessage());
         }

     }

     public static void sayPlay (String sentences,HttpServletRequest request,HttpServletResponse response) throws Exception{
         //获取tomcat 路径
         String ROOT = System.getProperty("catalina.home")+"\\webapps\\JavaWeb\\test.wav";
         //输出 wav IO流
         try{
             response.setHeader("Content-Type", "audio/mpeg");
             File file = new File(ROOT);
             int len_l = (int) file.length();
             byte[] buf = new byte[2048];
             FileInputStream fis = new FileInputStream(file);
             OutputStream out = response.getOutputStream();
             len_l = fis.read(buf);
             while (len_l != -1) {
                 out.write(buf, 0, len_l);
                 len_l = fis.read(buf);
             }

         }

     }
