這幾天寫代碼用到了文件輸出,在網上找到這個方法,超級好用,能準確輸出(word,excel,pdf,zip等),記下以後備用,哈哈
int _nread = 0;
byte[] _buffer = new byte[1024];
File tFile = new File(temp.getZipDir() + "\\" + zipFileName);
BufferedInputStream _buffInputStream =
new BufferedInputStream(Resources.getAsInputStream(tFile));
ServletOutputStream _outputStream = resp.getOutputStream();
while( (_nread= _buffInputStream.read(_buffer)) != -1 ) {
_outputStream.write(_buffer, 0, _nread);
_buffer = new byte[1024];
}
_buffInputStream.close();
_outputStream.flush();
_outputStream.close();
