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。
https://blog.csdn.net/weixin_43238452/article/details/109636200?spm=1001.2014.3001.5501
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)
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
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
/**

*/
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>20991231</SubscriptionExpiry><LicenseExpiry>20991231</LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>";
ByteArrayInputStream inputStream = new ByteArrayInputStream(s.getBytes());

license.setLicense(inputStream);

} catch (Exception e) {
e.printStackTrace();
}
return result;
}
public static void word2pdf(String docPath, String savePath) {
try {

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 {

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
@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();
}
