如果是直接生成word的话，用下面的代码：

// 导出报告 word文档     模板类型 正式节点才能导出报告
	@GetMapping("/exportReportWord")
	@ApiOperationSupport(order = 8)
	@ApiOperation(value = "导出报告 PDF 文档", notes = "")

		List<CmComplaintEntity> joints = cmComplaintService.listByIds(Func.toStrList(ids));

		String uuid = UUID.randomUUID().toString();
		Path zipPath = Paths.get(pathProperties.getReport(), uuid + ".zip");
		File zipFile = zipPath.toFile();
		if (zipFile.exists()) {
			zipFile.delete(); // 如果文件存在则先删除旧的文件
		}

		List<File> pdfFiles = null;

		try {
			if (!zipFile.getParentFile().exists()) {
				Files.createDirectories(zipPath.getParent());
			}

			pdfFiles = joints.stream()
					.map(joint -> {
						String fileName = joint.getWorkOrderNo();
						Path docxPath = Paths.get(pathProperties.getReport(), uuid, fileName + ".docx");
						Path pdfPath = Paths.get(pathProperties.getReport(), uuid, fileName + ".pdf");
						File docxFile = docxPath.toFile();
						File pdfFile = pdfPath.toFile();

						try {
							if (!docxFile.getParentFile().exists()) {
								Files.createDirectories(docxPath.getParent());
							}

							if (!docxFile.exists()) {
								Files.createFile(docxPath);
							}

							// 生成 Word 文档
							XWPFTemplate template = getXwpfTemplate(joint);
							try (FileOutputStream fos = new FileOutputStream(docxFile)) {
								template.write(fos);
							}

							// 转换 Word 到 PDF
							if (docxFile.exists()) {
								convertWordToPdf(docxFile, pdfFile);
							}

						} catch (Exception e) {
							e.printStackTrace();
						}
						return pdfFile;
					})
					.collect(Collectors.toList());

			// 压缩 PDF 文件
			ZipUtil.zipFile(pdfFiles, zipPath.toFile().getAbsolutePath());
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if (pdfFiles != null) {
				for (File f : pdfFiles) {
					if (f.exists()) {
						f.delete();
					}
				}
			}
			Path dirPath = Paths.get(pathProperties.getReport(), uuid);
			if (dirPath.toFile().exists()) {
				dirPath.toFile().delete();
			}
		}

		// 下载文件
		InputStream inStream = null;
		try {
			if (!zipFile.exists()) {
				return;
			}
			inStream = new FileInputStream(zipFile);
			response.reset();
			response.setContentType("application/zip");

			IoUtil.copy(inStream, response.getOutputStream());
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if (inStream != null) {
				try {
					inStream.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
			if (zipFile.exists()) {
				zipFile.delete(); // 压缩包也删除
			}
		}
	}


	/**

下面有一个依赖的工具类 

import net.lingala.zip4j.ZipFile;
import net.lingala.zip4j.exception.ZipException;
import net.lingala.zip4j.model.ZipParameters;
import net.lingala.zip4j.model.enums.CompressionLevel;
import net.lingala.zip4j.model.enums.CompressionMethod;


import java.io.File;
import java.nio.charset.Charset;
import java.util.List;

public class ZipUtil {

	public static void zipFile(File dir, String file) throws ZipException {
		// 生成的压缩文件
		ZipFile zipFile = new ZipFile(file);
		ZipParameters parameters = new ZipParameters();
		// 压缩方式
		parameters.setCompressionMethod(CompressionMethod.DEFLATE);
		// 压缩级别
		parameters.setCompressionLevel(CompressionLevel.FAST);
		 // 要打包的文件夹
		File[] list = dir.listFiles();
		// 遍历文件夹下所有的文件、文件夹
		for (File f: list) {
			if (f.isDirectory()) {
				zipFile.addFile(f.getPath(), parameters);
			} else {
				zipFile.addFile(f, parameters);
			}
		}
	}

	public static void zipFile(List<File> list, String file) throws ZipException {
		// 生成的压缩文件
		ZipFile zipFile = new ZipFile(file);
		ZipParameters parameters = new ZipParameters();
		// 压缩方式
		parameters.setCompressionMethod(CompressionMethod.STORE);

		for (File f: list) {
			if (f.isDirectory()) {
				zipFile.addFile(f.getPath(), parameters);
			} else {
				zipFile.addFile(f, parameters);
			}
		}
	}

	public static void unzip(String srcFile, String destDir) throws Exception {
		/** 判断文件是否存在 */
		File file = new File(srcFile);
		if (file.exists()) {
			ZipFile zipFile = new ZipFile(srcFile);
			// 设置编码格式中文设置为GBK格式
			zipFile.setCharset(Charset.forName("GBK"));
			// 解压压缩包
			zipFile.extractAll(destDir);
		}
	}

}

这个工具类依赖于

本文介绍了一个基于Java的文档处理方案，主要实现Word文档生成和PDF转换功能。系统使用poi-tl和Apache POI库生成Word文档，通过documents4j实现Word转PDF，并采用zip4j进行文件压缩。核心功能包括：1)根据模板动态生成Word文档；2)将Word批量转换为PDF；3)将多个PDF文件打包下载。代码展示了完整的文档处理流程，包括文件创建、格式转换、压缩打包和下载清理等操作，同时提供了异常处理和资源清理机制。该方案适用于需要批量生成和导出报告文档的业务场景。
