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。

- 创建模板，创建一份template2.docx文件，内容如下
- 编写代码

}

// 图片宽度、高度
int width = Units.toEMU(100), height = Units.toEMU(100);
// 添加图片信息，段落高度需要在模板中自行调整
run.addPicture(is, XWPFDocument.PICTURE_TYPE_PNG, (String) obj, width, height);
}
}
}
}
}
- 编写测试用例,并执行测试用例
@Test
void 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---------------");
}
生成得到被填充出来的文件。
