1.首先导入依赖
<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.11</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</artifactId><version>9.0.7</version></dependency>
2.代码部分
package com.pdf.util;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.OutputStream;import org.jsoup.Jsoup;import org.xhtmlrenderer.pdf.ITextFontResolver;import org.xhtmlrenderer.pdf.ITextRenderer;import com.lowagie.text.pdf.BaseFont;/*** 转换html为pdf* @author Uncle Liu**/public class Html2pdf {/*** 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*/// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/TR/xhtml1/DTD/xhtml1-transitional.dtd ">public static void html2pdf(String htmlFile, String pdfFile) throws Exception {// step 1String url = new File(htmlFile).toURI().toURL().toString();System.out.println(url);// step 2OutputStream os = new FileOutputStream(pdfFile);ITextRenderer renderer = new ITextRenderer();renderer.setDocument(url);// step 3 解决中文支持ITextFontResolver fontResolver = renderer.getFontResolver();if("linux".equals(getCurrentOperatingSystem())){//Linux下的和Windows的不一样，要自己下载，不要拷贝Windows的到LinuxfontResolver.addFont("/usr/share/fonts/chiness/simsun.ttc", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);}else{fontResolver.addFont("C:\\Windows\\WinSxS\\amd64_microsoft-windows-font-truetype-simsun_31bf3856ad364e35_10.0.17134.1_none_e089ab61d8d9374e\\simsun.ttc", 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 htmlFile = "D:\\WorkSpace\\IdeaProjects\\pdf\\src\\main\\resources\\templates\\u.html";String pdfFile = "c:/test.pdf";try {Html2pdf.html2pdf(htmlFile, pdfFile);} catch (FileNotFoundException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}}}
3.html页面
注意：html格式非常严格，图片地址这里用的是绝对路径（file:///D:/WorkSpace/IdeaProjects/pdf/src/main/resources/static/images/1.jpg）
如果是相对路径要在后台设置
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"/><title>Title</title><style>/*没有background-color生成的pdf一部分会是空白*/body{ text-align:center;border: 0px;margin: 0px;background-color:#FFFFFF;}.div{ margin:0 auto; width:1188px; height:auto;}body {/*中文支持*/font-family:SimSun;}</style></head><body><div class="div"><div><h2>123我</h2><img src="file:///D:/WorkSpace/IdeaProjects/pdf/src/main/resources/static/images/1.jpg" style="width: 20px;height: 20px"/><table border="1" cellspacing="0"><tr><td>eE额33</td><td>eE额33</td></tr><tr><td>eE额33</td><td>eE额33</td></tr><tr><td>eE额33</td><td>eE额33</td></tr><tr><td>eE额33</td><td>eE额33</td></tr></table></div></div></body></html>
4.生成pdf
超出页面长度时会自动分页
