因為需要圖片和中文，所以使用了pd4ml+freemarker來生成pdf
需要maven包
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.30</version>
</dependency>
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>flying-saucer-pdf</artifactId>
<version>9.1.17</version>
</dependency>
<dependency>
<groupId>com.pdf</groupId>
<artifactId>pdf-fonts</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/fonts.jar</systemPath>
</dependency>
<dependency>
<groupId>com.pdf</groupId>
<artifactId>pdf-pd4ml</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/pd4ml-370fx2pro.jar</systemPath>
</dependency>
<dependency>
<groupId>com.pdf</groupId>
<artifactId>pdf-sscss</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/ss_css2.jar</systemPath>
</dependency>
其中 flying-saucer-pdf、pdf-fonts、pdf-pd4ml 我是放在項目根目錄下的
要支持中文，還需要引入simsun.ttf字體文件，我是放在resources目錄下
生成pdf文件
/** * 生成pdf文件 * @author zengwei * @email 15797630391@163.com * @param ftlPath * @param ftlName * @param imageDiskPath * @param data * @param response * @return * @throws Exception */ public static OutputStream generateToServletOutputStream(String ftlPath, String ftlName, String imageDiskPath, Object data, HttpServletResponse response) throws Exception { // 獲取Freemarker配置 Configuration config = new Configuration(Configuration.VERSION_2_3_0); config.setDirectoryForTemplateLoading(new File(ftlPath)); config.setEncoding(Locale.CHINA, "utf-8"); // 得到模板內容 Template tpl = config.getTemplate(ftlName); StringWriter writer = new StringWriter(); tpl.process(data, writer); writer.flush(); String html = writer.toString(); OutputStream out = response.getOutputStream(); // 添加字體，以支持中文 ITextRenderer render = new ITextRenderer(); render.getFontResolver().addFont("font/simsun.ttf", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); render.setDocumentFromString(html); // html中如果有圖片，圖片的路徑則使用這里設置的路徑的相對路徑，這個是作為根路徑 if (imageDiskPath != null && !"".equals(imageDiskPath)) { render.getSharedContext().setBaseURL("file:/" + imageDiskPath); } // 能日賺30的手賺試玩平台，親測有效 // https://www.cnblogs.com/shiqiboy3974/p/13380267.html render.layout(); render.createPDF(out); render.finishPDF(); return out; }
創建controller調用生成pdf文件
/** * 生成pdf文件 * @author zengwei * @email 15797630391@163.com * @param response * @throws Exception */ @GetMapping("/downloadPdfFile") public void downloadPdfFile(HttpServletResponse response) throws Exception { String path = "template/"; //ftl路徑 String templateName = "template";//需要選用的模板名稱 String outFilePath = "template.pdf"; List<Map<String, Object>> labelList = new ArrayList<>(); Map<String, Object> label = new HashMap<>(); label.put("imgUrl", "https://profile.csdnimg.cn/0/6/D/3_zengweib208"); label.put("name", "NO1 CSDN:田間稻草人"); labelList.add(label); Map<String, Object> label2 = new HashMap<>(); label2.put("imgUrl", "https://profile.csdnimg.cn/0/6/D/3_zengweib208"); label2.put("name", "NO2 CSDN:田間稻草人"); labelList.add(label2); // 能日賺30的手賺試玩平台，親測有效 // https://www.cnblogs.com/shiqiboy3974/p/13380267.html Map<String, Object> map = new HashMap<>(); map.put("labelList", labelList); response.reset(); response.setCharacterEncoding("UTF-8"); response.setContentType("application/PDF;charset=utf-8"); response.setHeader("Content-Disposition", "attachment; filename=" + outFilePath); generateToServletOutputStream(path, templateName + ".ftl", path + "/images/", map, response); }
ftl模板放在項目根目錄下
ftl模板內容，body標簽中必須填入style="font-family: SimSun;",否則無法顯示中文
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"/> <title>Document</title> <style> @page { size: 250mm 320mm; } * { margin: 0; padding: 0; } ul { list-style: none; overflow: hidden; padding: 20px 20px 20px 20px; } html, body { width: 100%; height: 100%; } ul li { background: #fff; float: left; margin: 0 20px; padding: 10px; width: 200px; overflow: hidden; } .over_one_line { display: block; overflow: hidden; white-space: nowrap; text-overflow: ellipsis; } </style> </head> <!-- 能日賺30的手賺試玩平台，親測有效 https://www.cnblogs.com/shiqiboy3974/p/13380267.html --> <body style="font-family: SimSun;"> <ul> <#list labelList as label> <li> <img style="width: 200px;" src="${label.imgUrl}"/> <p class="over_one_line" style="padding-left: 10px">${label.name}</p> </li> </#list> </ul> </body> </html>
調用接口后生成pdf文件
