SpringBoot poi-tl通过模板占位符生成word文件

news 2024/10/24 15:21:19

简介：

开发中我们需要通过在word中使用占位符来动态渲染一些数据，本文讲解poi-tl实现动态生成word文档，包括表格循环，对象嵌套。

poi-tl官网文档 Poi-tl Documentation

1. word格式

这是我的test.word

这是导出后的out.docx文件

2. 依赖

首先pom.xml导入依赖

		<dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>5.2.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>5.2.2</version></dependency><dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.12.0</version></dependency>

3. 实现代码

import com.deepoove.poi.XWPFTemplate;
import com.deepoove.poi.config.Configure;
import com.deepoove.poi.plugin.table.LoopRowTableRenderPolicy;
import java.io.*;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;public class EditWordUtil {public static void main(String[] args) {String filePath = "D:/test.docx";try (FileInputStream resourceAsStream = new FileInputStream(new File(filePath));) {// 组装测试数据Map<String, Object> map = new HashMap<>();map.put("title", "日记");map.put("text", "好日子");map.put("score", 55);map.put("reward", "妈妈奖励我10块钱");map.put("imgUrl", "https://img2.baidu.com/it/u=485011689,3022056151&fm=253&fmt=auto&app=120&f=PNG?w=176&h=176");ArrayList<Map<String, Object>> list = new ArrayList<>();for (int i = 0; i < 4; i++) {HashMap<String, Object> maps = new HashMap<>();maps.put("name", "name" + i);maps.put("age", "age" + i);maps.put("address", "address" + i);list.add(maps);}map.put("lists", list);// 嵌套map数据HashMap<Object, Object> table = new HashMap<>();table.put("listTitle", "这是表格标题!");map.put("table", table);// 调用生成 Word 文件方法，将结果保存到本地EditWordUtil.createWordOfList("D:/out.docx", resourceAsStream, map);} catch (IOException e) {e.printStackTrace();}}// 将生成的 Word 保存到本地文件系统public static boolean createWordOfList(String outputPath, InputStream templatePath, Map<String, Object> dates) throws IOException {try (FileOutputStream out = new FileOutputStream(outputPath);BufferedOutputStream bos = new BufferedOutputStream(out)) {// 使用Configure.ConfigureBuilder而不是BuilderConfigureBuilder builder = Configure.builder();LoopRowTableRenderPolicy loopRowTableRenderPolicy = new LoopRowTableRenderPolicy();// 动态绑定for (Map.Entry<String, Object> entry : dates.entrySet()) {if (entry.getValue() instanceof ArrayList) {builder.bind(entry.getKey(), loopRowTableRenderPolicy);}}Configure configure = builder.build();// 读取模板并渲染数据XWPFTemplate template = XWPFTemplate.compile(templatePath, configure).render(dates);try {template.write(bos);template.close();} catch (Exception e) {e.printStackTrace();return false;}out.flush();bos.flush();}return true;}
