遇到的问题，当doc转换为html时不会将图像的线条给转换过来。只有在table表格中才可以转换为span标签。如果要作下滑线，可以放一个table的单元格只设定下边框就可以完美转换为html了。
将html转换为pdf

import java.io.FileOutputStream;
import java.io.OutputStream;
/**

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);
// 解决中文支持问题
ITextFontResolver fontResolver = renderer.getFontResolver();
/*fontResolver.addFont("C:\\Windows\\Fonts\\simsunb.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
*///宋体文件的相对路径
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

return true;

public static void main(String [] args){

try {
html2Pdf.convertHtmlToPdf("D:\\1.html","D:\\index.pdf");
