java本地可以发到linux不行,java 使用 ftp 在windows环境下可以正常下载文件，在linux环境下不行...
windows環(huán)境下使用
public static void dowmloadFtpWindos(String fileUuid, HttpServletRequest request,HttpServletResponse response) {
LmpFileInfo finfo = lmpFileInfoServiceClient.getByUuid(fileUuid);
String dfname = processFileName(request, finfo.getName());
response.setContentType("multipart/form-data;charset=UTF-8");
response.setHeader("Content-Disposition", "attachment;fileName=" + dfname);
FtpUtil ftpUtil = new FtpUtil();
try {
String saveurl = finfo.getSaveurl();
String targetPath = "";
String fileName = "";
if (saveurl != null && saveurl.lastIndexOf('/') > 0) {
targetPath = finfo.getSaveurl().substring(0, saveurl.lastIndexOf('/'));
fileName = finfo.getSaveurl().substring(saveurl.lastIndexOf('/') + 1);
}
ftpUtil.downFile(targetPath,fileName,response);
} catch (Exception e) {
e.printStackTrace();
} finally {
ftpUtil.disConFtp();
}
}
Lunix下使用
public static String dowmloadFtpLunix(String fileUuid, HttpServletRequest request, HttpServletResponse response) {
LmpFileInfo finfo = lmpFileInfoServiceClient.getByUuid(fileUuid);
String dfname = processFileName(request, finfo.getName());
response.setContentType("multipart/form-data;charset=UTF-8");
response.setHeader("Content-Disposition", "attachment;fileName=" + dfname);
FtpUtil ftpUtil = new FtpUtil();
try {
FTPClient ftp = ftpUtil.getFtpClient();
// 設置PassiveMode傳輸
ftp.enterLocalPassiveMode();
// 設置以二進制流的方式傳輸
ftp.setFileTransferMode(FTP.STREAM_TRANSFER_MODE);
ftp.setFileType(FTP.BINARY_FILE_TYPE);
String saveurl = finfo.getSaveurl();
String targetPath = "";
String fileName = "";
if (saveurl != null && saveurl.lastIndexOf('/') > 0) {
targetPath = finfo.getSaveurl().substring(0, saveurl.lastIndexOf('/'));
fileName = finfo.getSaveurl().substring(saveurl.lastIndexOf('/') + 1);
}
ftp.changeWorkingDirectory(targetPath);
InputStream input = ftp.retrieveFileStream(new String(fileName.getBytes("GBK"),"ISO-8859-1"));
OutputStream out = response.getOutputStream();
int buf = -1;
while ((buf = input.read()) != -1) {
out.write(buf);
}
out.flush();
input.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
ftpUtil.disConFtp();
}
// 返回值要注意，要不然就出現(xiàn)下面這句錯誤！
// java+getOutputStream() has already been called for this response
return null;
}
