最好的学习方法就是输出所学的知识使用poi实现简单的Word模板填充
参考：https://blog.csdn.net/LiuQjie/article/details/127918528
加入3个依赖包

创建一个.docx格式Word模板，填充的位置用${名称}代替
在测试目录下测试
@Test
public void run7(){

Map<String, Object> data = new HashMap<>();
//替换图片
Map<String, Object> picData = new HashMap<>();
data.put("${name}", "张三");
data.put("${sex}", "男");
data.put("${test}", "表格外的文本");
//指定图片地址
picData.put("${pic}", "C:\\Users\\admin\\Desktop\\路飞.jpg");
operateWord(data, picData);
}
//执行替换的方法
public static void operateWord(Map<String, Object> data, Map<String, Object> picData){
try {
//指定Word模板文件
FileInputStream is = new FileInputStream("C:\\Users\\admin\\Desktop\\template.docx");
XWPFDocument document = new XWPFDocument(is);
if (data.size() > 0) {
// 替换掉表格之外的文本(仅限文本)
ReplaceWord.changeText(document, data);
// 替换表格内的文本对象
ReplaceWord.changeTableText(document, data);
}
if (picData.size() > 0) {
// 替换内容图片
ReplaceWord.changePic(document, picData);
// 替换表格内的图片对象
ReplaceWord.changeTablePic(document, picData);
}
//导出替换后的文件
FileOutputStream out = new FileOutputStream("C:\\Users\\admin\\Desktop\\demo" + ".docx");
document.write(out);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}测试结果
