html如何word转pdf文件,html文件转换成pdf和word
1、html文件转成pdf
采用jar包有itext-asian.jar、itextpdf-5.5.5.jar、itext-pdfa-5.5.5.jar、itext-xtra-5.5.5.jar，为了保持html页面的全部格式，需要进行相关设置，代码如下：
private boolean convert2Pdf(InputStream htmlInputStream, String pdfFile, String padding) throwsFileNotFoundException, DocumentException {
String[] paddings= padding.split(",");float a1 = (float) (Float.valueOf(paddings[0]) * 0.77); //为了设置pdf的上下左右页边距float a2 = (float) (Float.valueOf(paddings[1]) * 0.77);float a3 = (float) (Float.valueOf(paddings[2]) * 0.77);float a4 = (float) (Float.valueOf(paddings[3]) * 0.77);
com.itextpdf.text.Document document= newcom.itextpdf.text.Document(
PageSize.A4, a1, a2, a3, a4);
PdfWriter pdfwriter= PdfWriter.getInstance(document, newFileOutputStream(pdfFile));
document.open();
CSSResolver cssResolver= newStyleAttrCSSResolver();//HTML
XMLWorkerFontProvider fontProvider = newXMLWorkerFontProvider(XMLWorkerFontProvider.DONTLOOKFORFONTS);
fontProvider.register("resources/garial.ttf", "Linrial"); //前面的ttf字体需要系统支持，后一个参数是html文件中的字体格式
fontProvider.register("resources/fzst_gb18030_20101201.ttf", "FZSongTi_GB18030");
fontProvider.register("resources/fzfangsong.ttf", "FZFangSong");
fontProvider.register("resources/fzheiti.ttf", "FZHeiTi");
fontProvider.register("resources/fzkaiti.ttf", "FZKaiTi");
fontProvider.register("resources/gtimes.ttf", "LinTimes");
CssAppliers cssAppliers= newCssAppliersImpl(fontProvider);
HtmlPipelineContext htmlContext= newHtmlPipelineContext(cssAppliers);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());final String IMG_PATH = pdfFile.substring(0, pdfFile.indexOf("/temp")) + "temp/"; //指定html文件的图片路径
htmlContext.setImageProvider(newAbstractImageProvider() {publicString getImageRootPath() {returnIMG_PATH;
}
});//Pipelines
PdfWriterPipeline pdf = newPdfWriterPipeline(document, pdfwriter);
HtmlPipeline html= newHtmlPipeline(htmlContext, pdf);
CssResolverPipeline css= newCssResolverPipeline(cssResolver, html);//XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser p= newXMLParser(worker);try{
p.parse(htmlInputStream, Charset.forName("UTF-8"));
}catch(IOException e) {
e.printStackTrace();return false;
}finally{
document.close();
}return true;
}
使用方式
convert2Pdf(new ByteArrayInputStream(html.getBytes()), "/root/123.pdf", padding)，其中html为html文件，需要转换为inputstream
2、html转为word
采用openoffice或者中标office，需要最新版本，jar包为jodconverter-2.2.2.jar、jodconverter-cli-2.2.2.jar需要把openoffice和web服务安装在同一个机器上
private booleanstartOfficeService() {final String paramStr = "\‘socket,host=localhost,port=8100;urp;\‘";
String pro= "/opt/neoshineoffice/program/soffice.bin -headless -accept="
+paramStr;
System.out.println("---中标Office后台服务启动中...>>>");try{
Runtime.getRuntime().exec(new String[] { "/bin/sh", "-c", pro }); //创建一个office服务进程；
} catch(Exception e) {
System.out.println("中标Office后台服务启动失败<<
e.printStackTrace();return false;
}
System.out.println("中标Office后台服务启动成功<<
}
privatecom.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection connectOfficeService() {
System.out.println("开始准备连接OFFICE服务...>>>");
com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection connection= newcom.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection("localhost", 8100);
Boolean flag= false;int count = 0; //初始连接OFFICE失败后再次连接的次数；
while (!flag) {try{
count++;
Thread.sleep((count+ 1) * 1000);
connection.connect();
flag= true;
System.out.println(connection);
}catch(Exception e) {
System.out.println("OFFICE服务连接失败<<
System.out.println("第" + count + "次重启OFFICE服务连接");if (count > 5) { //连接OFFICE失败5次后，停止连接；
e.printStackTrace();
System.out.println("-----无法启动OFFICE服务连接，请检查OFFICE安装情况！----错误信息："+e.getMessage());return null;
}
}
}
System.out.println("OFFICE服务连接成功<<
}
if(startOfficeService()) {
OpenOfficeConnection conn=connectOfficeService();if (conn != null) {
DocumentConverter convert= newOpenOfficeDocumentConverter(conn);
convert.convert(new File(rootPath + "/temp/resulted.html"), new File(rootPath + "/temp/" + reportName + ".doc"));
conn.disconnect();
}
}
