新建org.xhtmlrenderer.layout文件夹，新建一个java文件，将以下内容粘贴进去
package org.xhtmlrenderer.layout;

renderer.setDocumentFromString(html.toString());
ITextFontResolver fontResolver = renderer.getFontResolver(); if("linux".equals(getCurrentOperatingSystem())){ fontResolver.addFont("/usr/share/fonts/chiness/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.EMBEDDED); }else{ fontResolver.addFont("C:/Windows/Fonts/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/simfang.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/simhei.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/msyh.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/msyhbd.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/simkai.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/STKAITI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/STLITI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/仿宋_GB2312.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); fontResolver.addFont("C:/Windows/Fonts/楷体_GB2312.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); }
renderer.layout(); renderer.createPDF(os); os.close();
System.out.println("create pdf done!!");
}
public static String getCurrentOperatingSystem(){ String os = System.getProperty("os.name").toLowerCase(); System.out.println("---------当前操作系统是-----------" + os); return os; }
public static void main(String[] args) { String content = "html内容"; String pdfFile = "d:/testoone.pdf"; try { FileTypeConvertUtil.html2pdf(content, pdfFile); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } }
备注：html里面需要添加上一下代码
html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"); html.append("<html xmlns=\"http://www.w3.org/1999/xhtml\">").append("<head>") .append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />")
table的样式需要添加table-layout: fixed;word-break:break-strict;是为了中文代码换行。
