SpringBoot使用EasyPoi根据模板导出word or pdf

1、导出效果

1.1 wrod

1.2 pdf

2、依赖

        <!--word--><dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-base</artifactId><version>4.3.0</version></dependency><dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-web</artifactId><version>4.3.0</version></dependency><dependency><groupId>cn.afterturn</groupId><artifactId>easypoi-annotation</artifactId><version>4.3.0</version></dependency><!--pdf--><dependency><groupId>com.documents4j</groupId><artifactId>documents4j-local</artifactId><version>1.0.3</version></dependency><dependency><groupId>com.documents4j</groupId><artifactId>documents4j-transformer-msoffice-word</artifactId><version>1.0.3</version></dependency>

2、工具类

package com.skybird.iot.addons.productionManagement.qualityTesting.backend.util;import cn.afterturn.easypoi.word.WordExportUtil;
import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
import java.io.*;
import java.util.Map;
import javax.servlet.http.HttpServletResponse;
import org.apache.poi.xwpf.usermodel.XWPFDocument;public class EasyPoiUtil {/*** 根据模板导出word** @param map 数据* @param url 模板地址* @param tempFile 临时模板文件*/public static void exportWord(Map<String, Object> map, String url, File tempFile) {try {XWPFDocument doc = WordExportUtil.exportWord07(url, map);FileOutputStream fos = new FileOutputStream(tempFile);doc.write(fos);fos.close();} catch (Exception e) {e.printStackTrace();}}/*** word转pdf导出** @param response* @param tempFile word文档文件*/public static void wordToPdfExport(HttpServletResponse response, File tempFile) {response.setContentType("application/pdf");response.setHeader("Content-Disposition", "attachment; filename=name.pdf");try (InputStream docxInputStream = new FileInputStream(tempFile);OutputStream pdfOutputStream = response.getOutputStream()) {IConverter converter = LocalConverter.builder().build();converter.convert(docxInputStream).as(DocumentType.DOCX).to(pdfOutputStream).as(DocumentType.PDF).execute();// 通常不需要在这里调用 flush()，因为 execute()方法可能已经完成了它，但如果遇到特定问题，可以尝试调用它// pdfOutputStream.flush();} catch (Exception e) {// 设置适当的 HTTP 状态码和错误消息response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);// 可以在这里记录错误或向客户端发送错误消息（但注意，响应流可能已关闭）e.printStackTrace();} finally {// 清理临时文件if (!tempFile.delete()) {tempFile.deleteOnExit();}}}
}

3、模板

4、模板指令

5、接口

  @RequestMapping("exportWord")public void exportWord(HttpServletResponse response) throws IOException {response.setContentType("application/msword");response.setHeader("Content-disposition", "attachment;filename=name.docx");OutputStream outputStream = response.getOutputStream();Map<String, Object> map = new HashMap<>();putBaseInfo(map);putList(map);String url =Objects.requireNonNull(getClass().getClassLoader().getResource("templates/export.docx")).getPath();File tempFile = File.createTempFile("tempDoc", ".docx");EasyPoiUtil.exportWord(map, url, tempFile);InputStream in = new FileInputStream(tempFile);// 创建存放文件内容的数组byte[] buff = new byte[1024];// 所读取的内容使用n来接收int n;// 当没有读取完时,继续读取,循环while ((n = in.read(buff)) != -1) {// 将字节数组的数据全部写入到输出流中outputStream.write(buff, 0, n);}// 强制将缓存区的数据进行输出outputStream.flush();// 关流outputStream.close();in.close();tempFile.deleteOnExit();}@RequestMapping("exportPdf")public void exportPdf(HttpServletResponse response) throws IOException {Map<String, Object> map = new HashMap<>();putBaseInfo(map);putList(map);String url =Objects.requireNonNull(getClass().getClassLoader().getResource("templates/export.docx")).getPath();File tempFile = File.createTempFile("tempDoc", ".docx");EasyPoiUtil.exportWord(map, url, tempFile);EasyPoiUtil.wordToPdfExport(response, tempFile);}private void putBaseInfo(Map<String, Object> map) {map.put("technology", "EasyPoi");map.put("person", "JueYue");map.put("time", "2024-09-27");}private void putList(Map<String, Object> map) {List<Map<String, String>> list = new ArrayList<>();for (int i = 0; i < 10; i++) {Map<String, String> map1 = new HashMap<>();map1.put("name", "星晨");map1.put("age", "20");list.add(map1);}map.put("list", list);}
