import cn.hutool.core.lang.Assert;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

2.PDF工具类

import java.util.zip.ZipFile;
import java.util.zip.ZipOutputStream;
/** * @Classname PdfUtil * @Description * @Date 2020/11/20 17:01 * @Created by j */
public class PdfUtil { 
    private static String separator = File.separator;//文件夹路径分格符
    /** * word（docx）转pdf * @param wordPath docx文件路径 * @return 生成的pdf路径 */
    public static String convertDocx2Pdf(String wordPath) { 
        OutputStream os = null;
        InputStream is = null;
        try { 
            is = new FileInputStream(new File(wordPath));
            WordprocessingMLPackage mlPackage = WordprocessingMLPackage.load(is);
            Mapper fontMapper = new IdentityPlusMapper();
            fontMapper.put("隶书", PhysicalFonts.get("LiSu"));

            fontMapper.put("宋体扩展", PhysicalFonts.get("simsun-extB"));
            fontMapper.put("仿宋", PhysicalFonts.get("FangSong"));
            fontMapper.put("仿宋_GB2312", PhysicalFonts.get("FangSong_GB2312"));

            mlPackage.setFontMapper(fontMapper);

            //输出pdf文件路径和名称
            String fileName = "pdfNoMark_" + System.currentTimeMillis() + ".pdf";
// String pdfNoMarkPath = System.getProperty("java.io.tmpdir").replaceAll(separator + "$", "") + separator + fileName;
            /** * windows环境 */
            String pdfNoMarkPath = "D:" + separator + fileName;
            /** * linux环境 */
// String pdfNoMarkPath = "/java/word/" + separator + fileName;

            os = new java.io.FileOutputStream(pdfNoMarkPath);

            //docx4j docx转pdf
            FOSettings foSettings = Docx4J.createFOSettings();
            foSettings.setWmlPackage(mlPackage);
            Docx4J.toFO(foSettings, os, Docx4J.FLAG_EXPORT_PREFER_XSL);

            is.close();//关闭输入流
            os.close();//关闭输出流

            //添加水印
            return pdfNoMarkPath;
        } catch (Exception e) { 
            e.printStackTrace();
            try { 
                if(is != null){ 
                    is.close();
                }
                if(os != null){ 
                    os.close();
                }
            }catch (Exception ex){ 
                ex.printStackTrace();
            }
        }finally { 
            File file = new File(wordPath);
            if(file!=null&&file.isFile()&&file.exists()){ 
                file.delete();
            }
        }
        return "";
    }



}

3.测试

    @PostMapping("/export")
    public EcpResult export(@RequestBody Map<String,Object> params , HttpServletRequest request, HttpServletResponse response){ 
        String name  = System.currentTimeMillis() + ".docx";
        String tem = "D:/";
// String tem = "/java/word/";
        WordUtil.exportWord("word/export.docx",tem,name,params,request,response);
        PdfUtil.convertDocx2Pdf(tem+name);
        return EcpResult.success(tem+name);
    }

注意：

1、Centos和Windows环境

    在Windows环境下可以正常使用，但是在Liunx环境下需要配置中文字体， 将window上的字体打包（ C:\Windows\Fonts），选择中文字体就行，上传到Ubuntu系统（/usr/share/fonts/dejavu ）， 刷新缓存、重启服务就好。 1、Windows: C:\Windows\Fonts

2、Liunx:/usr/share/fonts/dejavu

3、刷新字体缓存：

fc-cache -fv

4、重启服务

2、配置缓存问题

第一次进行转换的时候读取很多配置文件，导致转换时间过长，可能会导致接口超时（测试最长10s左右）后面再次调用响应时间基本上在ms级别，建议在系统启动的时候进行配置缓存，也就是把对应的方法调用一次。
