java如何将wav的音频返给前端

        //返回响应内容类型
         response.setContentType("audio/wav");  
        OutputStream out = response.getOutputStream();  

老是报audio/wav 错误 说with preset Content-Type 'audio/wav'
改成response.setContentType("application/octet-stream");后可以传数据过去,但是不是音频文件,不知道前端能不能解析到

把这个博客甩给前端就行了前端如何接收后端返回content-Type为application/octet-stream格式的音频文件_天一城的博客-CSDN博客_content-type: application/octet-stream

FileInputStream inputStream = new FileInputStream("text"+uuid+".wav");
            int i = inputStream.available();

            byte[] buff = new byte[i];
            inputStream.read(buff);
            //关闭输入流
            inputStream.close();

            //返回响应内容类型

            response.setContentType("application/octet-stream");
            OutputStream out = response.getOutputStream();
            out.write(buff);
            out.close();

这是完整的代码
