linux服务器上下载的csv文件在window环境下用excel打开的乱码问题解决

response.setContentType("application/force-download;charset=utf-8");// 设置强制下载不打开
response.addHeader("Content-Disposition",
"attachment;fileName=" + fileName);// 设置文件名
byte[] buffer = new byte[1024];
FileInputStream fis = null;
BufferedInputStream bis = null;
try {
fis = new FileInputStream(file);
bis = new BufferedInputStream(fis);
OutputStream os = response.getOutputStream();
// 加上bom头，才不会中文乱码
os.write(new   byte []{( byte ) 0xEF ,( byte ) 0xBB ,( byte ) 0xBF });
int i = bis.read(buffer);
while (i != -1) {
os.write(buffer, 0, i);
i = bis.read(buffer);
}

System.out.println("success");
} catch (Exception e) {
e.printStackTrace();
} finally {
if (bis != null) {
try {
bis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (fis != null) {
try {
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
