Java使用easypoi填充数据到word

需要引入的Maven依赖

<dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-base</artifactId><version>4.4.0</version>
</dependency>
<dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-web</artifactId><version>4.4.0</version>
</dependency>
<dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-annotation</artifactId><version>4.4.0</version>
</dependency>
<dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.1</version>
</dependency>
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.1</version>
</dependency>

工具类(可直接使用或适当修改)

import jakarta.servlet.http.HttpServletResponse;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.*;
import java.net.URL;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;
import java.util.Map;public class FileUtil {public static void exportWordByModel(HttpServletResponse response, Map<String, Object> map, String modelFileName, String outFileName) {try {// 1.获取模板文件路径 - 重点//XWPFDocument word = WordExportUtil.exportWord07(modelFileName, map);有时候这种方式可以找到有时候找不到（不太清楚）String templatePath = filePath(modelFileName).getAbsolutePath();// 打印出模板文件的完整路径 - 校验路径是否存在File templateFile = new File(templatePath);if (templateFile.exists()) {System.out.println("模板文件存在: " + templateFile.getAbsolutePath());} else {System.out.println("模板文件不存在: " + templateFile.getAbsolutePath());}// 2.映射模板，替换数据XWPFDocument word = WordExportUtil.exportWord07(templatePath, map);// 3.设置返回参数的字符集response.reset();response.setHeader("Access-Control-Allow-Origin", "*");response.setContentType("application/msexcel");response.setContentType("text/html; charset=UTF-8");// 4.设置响应类型为Word文档response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document");// 5.中文文件名处理，否则报错String encodedFileName = URLEncoder.encode(outFileName, "UTF-8");response.setHeader("Content-Disposition", "attachment;filename=" + encodedFileName + ".docx");// 6.将Word文档发送到浏览器word.write(response.getOutputStream());} catch (Exception e) {e.printStackTrace();}}/*** 根据文件名获取文件对象* @param modelFileName* @return*/public static File filePath(String modelFileName) {// 获取类加载器ClassLoader classLoader = FileUtil.class.getClassLoader();// 尝试从类路径中加载资源URL resource = classLoader.getResource(modelFileName);return new File(resource.getFile());}
}

导出和填充接口实现
