doc文件轉換為html文件

遇到的問題，當doc轉換為html時不會將圖像的線條給轉換過來。只有在table表格中才可以轉換為span標簽。如果要作下滑線，可以放一個table的單元格只設定下邊框就可以完美轉換為html了。

將html轉換為pdf

package com.gsww.sxzz.controller.service;import com.lowagie.text.pdf.BaseFont; import org.xhtmlrenderer.pdf.ITextFontResolver; import org.xhtmlrenderer.pdf.ITextRenderer;import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.OutputStream;/*** Created by Carey on 15-2-2.*/ public class htmlToPdf {public boolean convertHtmlToPdf(String inputFile, String outputFile){try {OutputStream os = new FileOutputStream(outputFile);ITextRenderer renderer = new ITextRenderer();String url = new File(inputFile).toURI().toURL().toString();renderer.setDocument(url);// 解決中文支持問題ITextFontResolver fontResolver = renderer.getFontResolver();/*fontResolver.addFont("C:\\Windows\\Fonts\\simsunb.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); *///宋體文件的相對路徑fontResolver.addFont("C:\\Windows\\Fonts\\simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); renderer.getSharedContext().setBaseURL("file:/D:/");renderer.layout();renderer.createPDF(os);os.flush();os.close();} catch (Exception e) {// TODO Auto-generated catch block e.printStackTrace();}return true;}public static void main(String [] args){htmlToPdf html2Pdf =new htmlToPdf();try {html2Pdf.convertHtmlToPdf("D:\\1.html","D:\\index.pdf");} catch (Exception e) {e.printStackTrace();}} }
