引言:
最近公司在做一個教育培訓學習及線上考試的專案,本人主要從事網路課程模組,主要做課程分類,課程,課件的建立及線上學習和統計的功能,因為課件涉及到多種型別,像視訊,音訊,圖文,外部連結及文件型別.其中就涉及到一個問題,就是文件型課件課程在網頁上的展示和學習問題,因為要線上統計學習的課程,學習的人員,學習的時長,所以不能像傳統做法將文件下載到本地學習,那樣就不受系統控制了,所以最終的方案是,在上傳文件型課件的時候,將其檔案對應的轉換成HTML檔案,以便在網頁上能夠瀏覽學習
下邊主要針對word,pdf和txt文字檔案進行轉換
一:Java實現將word轉換為html

二:Java實現將Pdf轉換為html
1: 引入依賴
<dependency> <groupId>net.sf.cssbox</groupId> <artifactId>pdf2dom</artifactId> <version>1.7</version> </dependency> <dependency> <groupId>org.apache.pdfbox</groupId> <artifactId>pdfbox</artifactId> <version>2.0.12</version> </dependency> <dependency> <groupId>org.apache.pdfbox</groupId> <artifactId>pdfbox-tools</artifactId> <version>2.0.12</version> </dependency>
2:程式碼Demo
public class PdfToHtml { /* pdf轉換html */ public void pdfToHtmlTest(String inPdfPath,String outputHtmlPath) { // String outputPath = "C:\\works\\files\\ZSQ保密知識測試題庫.html"; //try() 寫在()裡面會自動關閉流 try{ BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(outputHtmlPath)),"utf-8")); //載入PDF文件 //PDDocument document = PDDocument.load(bytes); PDDocument document = PDDocument.load(new File(inPdfPath)); PDFDomTree pdfDomTree = new PDFDomTree(); pdfDomTree.writeText(document,out); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) throws IOException { PdfToHtml ph=new PdfToHtml(); String pdfPath="C:\\works\\files\\武研中心行政考勤制度.pdf"; String outputPath="C:\\works\\files\\武研中心行政考勤制度.html"; ph.pdfToHtmlTest(pdfPath,outputPath); } }
三:Java實現將TXT轉換為html
/* * txt文件轉html filePath:txt原檔案路徑 htmlPosition:轉化後生成的html路徑 */ public static void txtToHtml(String filePath,String htmlPosition) { try { //String encoding = "GBK"; File file = new File(filePath); if (file.isFile() && file.exists()) { // 判斷檔案是否存在 InputStreamReader read = new InputStreamReader(new FileInputStream(file),"GBK"); // 考慮到編碼格式 BufferedReader bufferedReader = new BufferedReader(read); // 寫檔案 FileOutputStream fos = new FileOutputStream(new File(htmlPosition)); OutputStreamWriter osw = new OutputStreamWriter(fos,"GBK"); BufferedWriter bw = new BufferedWriter(osw); String lineTxt = null; while ((lineTxt = bufferedReader.readLine()) != null) { bw.write("   "+lineTxt + "</br>"); } bw.close(); osw.close(); fos.close(); read.close(); } else { System.out.println("找不到指定的檔案"); } } catch (Exception e) { System.out.println("讀取檔案內容出錯"); e.printStackTrace(); } }
