附件下载

Question

附件下载，为什么点击下载的时候是把我的方法.do下载下来了，代码如下
[code="java"]
@RequestMapping
public void viewFileUpload(Long fileId, HttpServletResponse response) throws Exception{
AssetBase file = assetBaseService.findByPrimaryKey(fileId);
/*ServletOutputStream out = response.getOutputStream();
out.write(file.getFileData());
out.flush();
out.close();*/
byte[] data = file.getFileData();
response.reset();
response.setHeader("Content-Disposition", "attachment;");

response.setContentType("application/octet-stream;charset=UTF-8");

OutputStream outputStream = new BufferedOutputStream(response.getOutputStream());

outputStream.write(data);

outputStream.flush();

outputStream.close();

}

[/code]

Answer 1

你试试这种方式
public void downloadLocal(HttpServletResponse response) throws FileNotFoundException {
// 下载本地文件
String fileName = "Operator.doc".toString(); // 文件的默认保存名
// 读到流中
InputStream inStream = new FileInputStream("c:/Operator.doc");// 文件的存放路径
// 设置输出的格式
response.reset();
response.setContentType("bin");
response.addHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
// 循环取出流中的数据
byte[] b = new byte[100];
int len;
try {
while ((len = inStream.read(b)) > 0)
response.getOutputStream().write(b, 0, len);
inStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
