Java使用ftl模板文件生成Word

一、写在前面

最近在项目中使用打印功能，发现这个功能我已经写过多次了，下面这个文章的发步日期在2020年，不得不感慨时间之快啊。

下面介绍一下应用场景：这次项目依旧是springboot项目，使用ftl模版生成的word文件。比上一版相比更加灵活而且实用性更高，还可插入base64图片进行展示
关于ftl模板我会简单介绍一下使用的心得，其实也是一些标签而已，熟悉以后操作起来也比较快

二、word转ftl模板，ftl标签简单介绍

1.找到使用的word模板（如图是我自己编写的一个word模板，后续会以此进行操作）

讯享网

2.左上角点击另存为xml文件

3.直接将保存的xml文件改后缀名为 ftl 然后放到项目 resources/static 目录下。进去之后idea会自动格式化，如果没有，建议按ctrl+f搜索对应的汉字进行定位（注：模板必须在static目录下,改个英文名防止乱码）

4.标签及语法

（1）替换标签可以是对象点属性也可以是单个变量

(2) 循环标签，如图会根据list的大小进行循环赋值

（3）判断标签如图，第一个为判断cks遍历下标是否大于5，第二层为判断cks是否拥有下一个数据

5.代码编写

1.导入maven依赖，freemarker和word工具类依赖aspose-words，后者可点击下载，下载jar包后自行打入maven仓库，我是直接导入的依赖坐标

 <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> </dependency> <dependency> <groupId>com.luhuiguo</groupId> <artifactId>aspose-words</artifactId> <version>22.10</version> </dependency> 

2.模板替换工具类

讯享网 import freemarker.template.Configuration; import freemarker.template.Template; import freemarker.template.Version; / * * @param dataMap 存储数据的map集合 * @param savePath 生成word保存路径 */ public static void ftl2Word(Map<String, Object> dataMap, String savePath) { 
    try { 
    Configuration configuration = new Configuration(new Version("2.3.0")); configuration.setDefaultEncoding("utf-8"); //.ftl配置文件所在路径 Template template = configuration.getTemplate("demo.ftl", "utf-8"); /*File file = new File("resources/static"); String absolutePath = file.getAbsolutePath();*/ //上面获取路径有bug,absolutePath 既存demo.ftl的路径，不包含demo.ftl // 如：D:\IdeaProjectsTwo\beauty-master\beauty-main\src\main\resources\static configuration.setDirectoryForTemplateLoading(new File(absolutePath)); //输出文档路径及名称 File outFile = new File(savePath); Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"), 10240); template.process(dataMap, out); out.close(); } catch (Exception e) { 
    e.printStackTrace(); } } 

3.word工具类

/ * @Author: SongTiankai * @Description: word工具类 * @Date: 2022/12/9 19:34 * @Version: 1.0 */ public class WordUtil { 
    / * @Description: 验证aspose.word组件是否授权：无授权的文件有水印标记 */ public static boolean isWordLicense() { 
    boolean result = false; try { 
    String s = "<License><Data><Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products><EditionType>Enterprise</EditionType><SubscriptionExpiry></SubscriptionExpiry><LicenseExpiry></LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>"; ByteArrayInputStream inputStream = new ByteArrayInputStream(s.getBytes()); com.aspose.words.License license = new com.aspose.words.License(); license.setLicense(inputStream); result = true; } catch (Exception e) { 
    e.printStackTrace(); } return result; } public static void word2pdf(String docPath, String savePath) { 
    try { 
    String s = "<License><Data><Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products><EditionType>Enterprise</EditionType><SubscriptionExpiry></SubscriptionExpiry><LicenseExpiry></LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>"; ByteArrayInputStream is = new ByteArrayInputStream(s.getBytes()); License license = new License(); license.setLicense(is); com.aspose.words.Document document = new com.aspose.words.Document(docPath); document.save(new FileOutputStream(new File(savePath)), SaveFormat.PDF); } catch (Exception e) { 
    e.printStackTrace(); } } public static void word2Image(String docPath, String savePath) { 
    try { 
    String s = "<License><Data><Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products><EditionType>Enterprise</EditionType><SubscriptionExpiry></SubscriptionExpiry><LicenseExpiry></LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>"; ByteArrayInputStream is = new ByteArrayInputStream(s.getBytes()); License license = new License(); license.setLicense(is); com.aspose.words.Document document = new com.aspose.words.Document(docPath); document.save(new FileOutputStream(new File(savePath)), SaveFormat.PNG); } catch (Exception e) { 
    e.printStackTrace(); } } } 

6.工具测试

1.测试代码

讯享网@ApiOperation("word测试接口") @PostMapping("/testCreat") public ResultData testCreat() { 
    Map<String, Object> dataMap = new HashMap<>(); dataMap.put("ckd", "生产一车间"); dataMap.put("llrq", DateUtil.format(new Date(), "yyyy-MM-dd HH:mm:ss")); dataMap.put("llbm", "领料部"); dataMap.put("kgy", "王武"); dataMap.put("zg", "占山"); dataMap.put("llr", "里斯"); WordUtil.ftl2Word(dataMap, "D:\\home\\word\\ckd.doc"); WordUtil.word2Image("D:\\home\\word\\ckd.doc", "D:\\home\\word\\ckd.png"); WordUtil.word2pdf("D:\\home\\word\\ckd.doc", "D:\\home\\word\\ckd.pdf"); return new SuccessResultData(); } 

2.pdf

3.word

4.png

7.小结

至此功能实现，今天太晚了，明天研究一下路径获取，更新后给大家贴代码！
如果对你有帮助，希望可以一键三连！
感谢！
