我有幾個文件保存在我的本地目錄中。一個視頻文件和一個 xml文件。視頻文件的詳細信息將存儲在xml文件中。For循環中的Java文件迭代
我們正在將視頻從一個系統移動到另一個系統。
將視頻文件和xml數據從一個系統上傳到另一個系統
系統,需要檢查其他系統中的視頻標題,並且只有在相同標題不存在的情況下才能上傳 。這工作正常。但上傳發生了4次,而不是2次 次。請幫忙。
這裏是主代碼:
List<File> videoFiles = new ArrayList<File>();
List<File> xmlFiles = new ArrayList<File>();
File[] allVideos = checkVideos();
for(File file:allVideos) {
if(file.getName().endsWith("flv")) {
videoFiles .add(file);
}
if(file.getName().endsWith("xml")) {
xmlFiles .add(file);
}
}
System.out.println(videoFiles.size());
System.out.println(xmlFiles.size());
processUpload(videoFiles ,xmlFiles);
這裏是方法:
private static void processUpload(List<File> videoFiles, List<File> xmlFiles) throws ParserConfigurationException, SAXException, IOException, ApiException {
NodeList nodes = null;
File video= null;
File xml = null;
String title = null;
String localFileTitle = null;
Media newMedia = null;
for(int i=0;i < videoFiles.size();i++) {
System.out.println("videoFiles.getName() ->"+videoFiles.get(i).getName());
video= videoFiles.get(i);
for(int j=0;j < xmlFiles.size();j++) {
xml = xmlFiles.get(j);
System.out.println("xmlFiles.getName() ->"+xmlFiles.get(i).getName());
nodes = parseXml(xml);
localFileTitle = processNodes(nodes);
title = checkTitles(localFileTitle);
newMedia = initiateUploadProcess(flv, title);
}
}
}
private static NodeList parseXml(File xmlFile) throws ParserConfigurationException, SAXException, IOException {
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(xmlFile);
doc.getDocumentElement().normalize();
//System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
NodeList nList = doc.getElementsByTagName("video");
return nList;
}
private static String processNodes(NodeList nodes) {
String fileTitle = null;
if(nodes.getLength() >= 1) {
for (int temp = 0; temp < nodes.getLength(); temp++) {
Node nNode = nodes.item(temp);
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
fileTitle = eElement.getElementsByTagName("title").item(0).getTextContent();
if(fileTitle != null) {
//System.out.println("Local File Title ------>"+fileTitle);
}
}
}
}
return fileTitle;
}
private static String checkTitles(String localTitle) throws ApiException {
String title = null;
MediaList mediaResponse = fetchVideos(caID);
if(mediaResponse.totalCount >= 1) {
for(MediaEntry media:mediaResponse.objects) {
if(!localTitle.equals(media.name)) {
System.out.println("Titles are not same. Need to return");
title = localTitle;
}
}
}
return title ;
}
private static MediaEntry initiateUploadProcess(File videoFile,
String localFileTitle) throws ApiException, ParserConfigurationException, SAXException, IOException {
UploadToken ktoken = null;
UploadMedia entry = null;
MediaEntry mediaEntry = null;
ktoken = generateToken();
if (ktoken != null) {
//System.out.println("ktoken.id ----------->" + ktoken.id);
if (ktoken.id != null) {
uploadToken(ktoken.id, flvFile);
entry = uploadMediaToChannel(categoryID, categoryName, localFileTitle);
if (entry.id != null) {
System.out.println("entry.id ------->" + entry.id);
mediaEntry = addMediaContent(ktoken.id, entry.id);
}
}
}
return mediaEntry;
}
這裏是輸出:
videoFiles.getName() ->22701846_91167469.flv
xmlFiles.getName() ->22701846_91167469.xml
Titles are not same. Need to return
Titles are not same. Need to return
video.id ------->0_50wh1m4p
xmlFiles.getName() ->22701846_91167469.xml
Titles are not same. Need to return
Titles are not same. Need to return
video.id ------->0_79v605ue
videoFiles.getName() ->22701846_91477939.flv
xmlFiles.getName() ->22701846_91477939.xml
Titles are not same. Need to return
Titles are not same. Need to return
video.id ------->0_0kihent1
xmlFiles.getName() ->22701846_91477939.xml

這是2016年你爲什麼不使用新的文件API? – fge
