Java文件下载ContentType设置

String filePath=””;

File file=new File(filePath);

//解决乱码问题

String filename=URLEncoder.encode(file.getName(),”utf-8″);

//重置输出流

response.reset();

Response.AddHeader(“Content-Disposition”, “attachment;filename=”+filename);//设置文件名

response.addHeader(“Content-Length”,file.length);//设置下载文件大小

response.setContentType(“application/octet-stream”);//设置文件类型

OutputStream toClient=new BufferedOuntputStream( response.getOutputStream() );//获取二进制输出流

//读取文件数据

InputStream fis=new BufferedInputStream(new FileInputStream(filePath));

byte[] buffer=new byte[file.length()];

fis.read(buffer);

fis.close();

//输出文件数据

toClient.write(buffer);

toClient.close();
