先講講思路：
第一步：使用 poi 將word轉換成 html，這裏代碼一搜一堆沒什麼好說的，千篇一律。
（值得注意的地方是IText 根據html生成pdf文件的時候，會驗證html文件是否標準，例如通過poi轉換的出來的html文件的一些標籤會缺少標籤閉合 ” / “ :
舉個栗子：
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<img src="test/0.jpg" style="width:5.765972in;height:8.647917in;vertical-align:text-bottom;">
這是我直接用pio生成的html中的一部分, META、img 標籤明顯就沒有對應閉合標籤。如果用這種html進行轉換是沒有辦法通過itext 的校驗的。會出現以下異常
錯誤： “The element type "meta" must be terminated by the matching end-tag "</meta>".”
org.xhtmlrenderer.util.XRRuntimeException: Can't load the XML resource (using TRaX transformer). org.xml.sax.SAXParseException: The element type "meta" must be terminated by the matching end-tag "</meta>". 。
從錯誤分析也知道是我們的html不規範拉，我們採用第三方 jar 包Jsoup， 直接調用 parse方法 我們的html就標準啦！
因爲遇到這個問題讓我頭疼了半天，沒想到就這麼輕鬆的解決了，發個博文支援一下遇到該問題的小夥伴們 ！
下面是pio轉換html 的代碼：
package com.smart.sys.core.service.io.poi;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.converter.PicturesManager;
import org.apache.poi.hwpf.converter.WordToHtmlConverter;
import org.apache.poi.hwpf.usermodel.Picture;
import org.apache.poi.hwpf.usermodel.PictureType;
import org.jsoup.Jsoup;
import org.w3c.dom.Document;

} catch (Exception e) {
e.printStackTrace();
}
}
//輸出html文件
public static void writeFile(String content, String path) {

//word 轉 html
public static void convert2Html(String fileName, String outPutFile)
throws TransformerException, IOException,
ParserConfigurationException {

if(pics!=null){
for(int i=0;i<pics.size();i++){

System.out.println();
try {
pic.writeImageContent(new FileOutputStream("D:/test/"
+ pic.suggestFullFileName()));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
Document htmlDocument = wordToHtmlConverter.getDocument();
ByteArrayOutputStream out = new ByteArrayOutputStream();
DOMSource domSource = new DOMSource(htmlDocument);
StreamResult streamResult = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
serializer.setOutputProperty(OutputKeys.METHOD, "HTML");
serializer.transform(domSource, streamResult);
out.close();
writeFile(new String(out.toByteArray()), outPutFile);
}
}
好了第二步生成pdf ，我直接上代碼了 ！
package com.smart.sys.core.service.io.itext;
import com.lowagie.text.pdf.BaseFont;
import org.xhtmlrenderer.pdf.ITextFontResolver;
import org.xhtmlrenderer.pdf.ITextRenderer;
import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
/**
* Created by Carey on 15-2-2.
*/
public class Html2Pdf {
public boolean convertHtmlToPdf(String inputFile, String outputFile)
throws Exception {
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);
//解決圖片的相對路徑問題
renderer.getSharedContext().setBaseURL("file:/D:/test");
renderer.layout();
renderer.createPDF(os);
os.flush();
os.close();
return true;
}
public static void main(String [] args){
Html2Pdf html2Pdf =new Html2Pdf();
try {
html2Pdf.convertHtmlToPdf("D:\\1.html","D:\\index.pdf");
} catch (Exception e) {
e.printStackTrace();
}
}
}
pdf 的轉換的詳細細節也是參考了一位大神的代碼，人家寫的非常詳細，我這裏也不再贅述 、這裏附上鍊接 ：

所需jar包
iText-2.0.8.jar
core-renderer.jar
iTextAsian.jar
iTextAsianCmaps.jar
jsoup-1.8.1.jar
