前言

使用word模板生成文件，如下图，将左侧的模板生成为右侧的填充word文档。
在这里插入图片描述

操作方式

引入依赖

		 <!-- https://mvnrepository.com/artifact/com.itextpdf/itextpdf --><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.13.3</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-excelant</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-examples</artifactId><version>4.1.2</version></dependency>

创建模板，创建一份template2.docx文件，内容如下
编写代码

编写测试用例,并执行测试用例

 @Testvoid testWord() throws Exception {Map<String, Object> data = new HashMap<>();Map<String, Object> picData = new HashMap<>();data.put("${year}", "2023");data.put("${month}", "06");data.put("${date}", "20");data.put("${birthday}", "2000年6月11日");data.put("${name}", "王小鱼");data.put("${sex}", "女");data.put("${address}", "北京市朝阳区光明街道幸福小区301号");data.put("${phoneno}", "1380000000");picData.put("${pic}", "D:\\test\\dog.jpg");DocxUtil.parseDocTemplate("D:\\test\\template2.docx","D:\\test\\template2_out.docx",data,picData);System.out.println("----------------end---------------");}
