ITextRenderer生成PDF，如何强制分页

ITextRenderer render = new ITextRenderer(); ITextFontResolver font = rendergetFontResolver(); try { fontaddFont(thisgetClass()getResource(PDF_FONT)toString() substring(5), BaseFontIDENTITY_H, BaseFontNOT_EMBEDDED); } catch (DocumentException e) { eprintStackTrace(); } catch (IOException e) { eprintStackTrace(); } StringBuffer xhtml = new StringBuffer(XHTML_HEAD); xhtmlappend(html); xhtmlappend(XHTML_FOOT); rendersetDocumentFromString(xhtmltoString()); renderlayout(); ByteArrayOutputStream os = new ByteArrayOutputStream(); rendercreatePDF(os); osclose(); 其中xhtml是一个包含了多个表单的HTML代码，现在要实现导出的PDF文件中一个表单占一页

我有完整代码

下面是方法，直接调用

public static void sign(String beforePdfpath,String afterPdfpath,String pngpath) throws Exception {

// KeyStore ks = KeyStoregetInstance("pkcs12");

// ksload(new FileInputStream("demop12"),"123456"toCharArray()); //123456为私钥密码

// String alias = (String) ksaliases()nextElement();

// PrivateKey key = (PrivateKey) ksgetKey(alias, "123456"toCharArray());

// Certificate[] chain = ksgetCertificateChain(alias);

Logd("pdfd", "do-1");

PdfReader reader = new PdfReader(beforePdfpath); //源文件

Logd("pdfd", "do-1-01");

FileOutputStream fout = new FileOutputStream(afterPdfpath);

Logd("pdfd", "do-1-1");

PdfStamper stp = PdfStampercreateSignature(reader, fout, '\0');

PdfSignatureAppearance sap = stpgetSignatureAppearance();

// sapsetCrypto(key, chain, null, PdfSignatureAppearanceVERISIGN_SIGNED);

Logd("pdfd", "do-2");

sapsetReason("");

sapsetLocation("");

sapsetContact(">

插入文本时样式可以用Font来定义：

Document doc = new Document();

docopen();

Paragraph text = new Paragraph("your text", new Font(FontgetFamily("TIMES_ROMAN"), 18, FontBOLD));

textsetAlignment(ElementALIGN_CENTER);

docadd(text);

以前插入过PDF文档，是用PdfReader读取然后用PdfWriter插入。插入应该是一样的原理：

PdfWritergetImportedPage(new PdfReader(bufferdInputStream), pageNumber);

/ 新建一个字体,iText的方法

STSongStd-Light 是字体，在iTextAsianjar 中以property为后缀

UniGB-UCS2-H 是编码，在iTextAsianjar 中以cmap为后缀

H 代表文字版式是横版，相应的 V 代表竖版
