1、maven文件下载
<dependency> <groupId>com.itextpdf</groupId> <artifactId>itextpdf</artifactId> <version>5.5.9</version></dependency> <dependency> <groupId>com.itextpdf.tool</groupId> <artifactId>xmlworker</artifactId> <version>5.5.9</version></dependency> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-asian</artifactId> <version>5.2.0</version></dependency> <dependency><groupId>org.xhtmlrenderer</groupId><artifactId>flying-saucer-pdf-itext5</artifactId><version>9.0.3</version></dependency>
2、重写Breaker.java文件，用于中文换行
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;/** Breaker.java* Copyright (c) , Torbj�rn Gannholm, * Copyright (c) Wisconsin Court System** This program is free software; you can redistribute it and/or* modify it under the terms of the GNU Lesser General Public License* as published by the Free Software Foundation; either version 2.1* of the License, or (at your option) any later version.** This program is distributed in the hope that it will be useful,* but WITHOUT ANY WARRANTY; without even the implied warranty of* MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

3、html转换pdf代码
/*** 文件格式转换工具类** @author lz** -07-01 上午10:52:22*/public class FileTypeConvertUtil {/*** 将HTML转成PD格式的文件。html文件的格式比较严格* @param htmlFile* @param pdfFile* @throws Exception*/public static void html2pdf(String content, String pdfFile) throws Exception {OutputStream os = new FileOutputStream(pdfFile);ITextRenderer renderer = new ITextRenderer();StringBuffer html = new StringBuffer(); content = content.replace("宋体", "SimSun");content = content.replace("黑体", "SimHei");content = content.replace("微软雅黑", "Microsoft YaHei");content = content.replace("微软正黑体", "Microsoft JhengHei");content = content.replace("新宋体", "NSimSun");content = content.replace("仿宋", "FangSong");content = content.replace("楷体", "KaiTi");content = content.replace("仿宋_GB2312", "FangSong_GB2312");content = content.replace("楷体_GB2312", "KaiTi_GB2312");content = content.replace("font-family:"", "font-family:SimSun;");content = content.replace("font-family:""", "font-family:SimSun;");// DOCTYPE 必需写否则类似于 这样的字符解析会出现错误 html.append("<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"); html.append("<html xmlns=\"/1999/xhtml\">").append("<head>") .append("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" />").append("<meta name=\"viewport\" content=\"initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width\"/>").append("<link rel=\"stylesheet\" href=\"/web/css/frame.css\"/>").append("<style type=\"text/css\" mce_bogus=\"1\">"+ "body {font-family: 宋体;} "+ "table { border-collapse: collapse; table-layout: fixed;word-break:break-strict;font-size: 10px; width: 100%;text-align: center;widths:\"50;10;40\"}"+ "td {word-break:break-all;word-wrap : break-word; } "+ "@page { size:210mm 297mm;margin: 0.25in; -fs-flow-bottom: \"footer\"; -fs-flow-left: \"left\"; -fs-flow-right: \"right\"; padding: 1em; } "+ "#footer { font-size: 90%; font-style: italic; position: absolute; top: 0; left: 0; -fs-move-to-flow: \"footer\"; } "+ "#pagenumber:before { content: counter(page); } #pagecount:before {content: counter(pages); }</style>").append("</head>") .append("<body style = \"font-family: SimSun;\">"+ "<div style=\"width: 700px;\"><div id=\"footer\" style=\"\"> Page <span id=\"pagenumber\"/> of <span id=\"pagecount\"/> </div>").append("<div class='inner' style='width:698px;overflow-x:auto;font-size:14px;color:#333;font-family:微软雅黑;line-height:2;'>");html.append("<div>"+content+"</div></div></div>"); html.append("</body></html>");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\" \"/TR/xhtml1/DTD/xhtml1-transitional.dtd\">"); html.append("<html xmlns=\"/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。
