util工具类

import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
import java.io.*;
public class PdfUtil {
　　/**
 　　* word转pdf
     * @param wordFilePath word文件路径
     * @param pdfFilePath  pdf文件路径
     * @return 成功或失败
     */
    public static boolean docxToPdf(String wordFilePath, String pdfFilePath) {
        boolean result = false;
 
        File inputFile = new File(wordFilePath);
        File outputFile = new File(pdfFilePath);
        try {
            InputStream inputStream = new FileInputStream(inputFile);
            OutputStream outputStream = new FileOutputStream(outputFile);
            IConverter converter = LocalConverter.builder().build();
            converter.convert(inputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();
 
            outputStream.close();
            result = true;
        } catch (Exception e) {
             
            e.printStackTrace();
        }
 
        return result;
    }
}

控制器层做测试，支持doc docx

//   http://localhost:8080/convert/word2pdf
    @RequestMapping("/word2pdf")
    public void word2pdf(HttpServletResponse response) {
//        String wordPath = "F:\\gxg\\ftpDownload\\test.docx";
//        String pdfPath = "F:\\gxg\\ftpDownload\\test.pdf";

        String wordPath = "F:\\gxg\\ftpDownload\\需求分析报告.xiexiaochuan.doc";
        String pdfPath = "F:\\gxg\\ftpDownload\\需求分析报告.pdf";

        Convert2Pdf.doc2Pdf(wordPath,pdfPath);
        System.out.println("转换成功");
        File file = new File(pdfPath);
        ResponseUtil.onlineReader(file,response);

        System.out.println("执行完毕");
    }

在线预览，附件下载 工具包

在这里插入代码片package com.example.house.SYSDBA.util;

import javax.servlet.http.HttpServletResponse;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.net.URLEncoder;

public class ResponseUtil {
    public static void responseBrowser(File file, HttpServletResponse response){
        //下面的是进行响应客户端的测试代码
        try {
            FileInputStream fileInputStream = new FileInputStream(file);
            //设置Http响应头告诉浏览器下载这个附件,下载的文件名也是在这里设置的

            System.out.println("file.getName()   >>>"+file.getName());

            response.setHeader("Content-Disposition", "attachment;fileName=" + URLEncoder.encode(file.getName(), "UTF-8"));
           // response.setHeader("Content-Disposition", "inline;fileName=" + URLEncoder.encode(file.getName(), "UTF-8"));
            System.out.println("file.getPath() >>>>>>"+file.getPath());

            OutputStream outputStream = null;

                outputStream = response.getOutputStream();

            byte[] bytes = new byte[2048];
            int len = 0;
            while ((len = fileInputStream.read(bytes))>0){
                outputStream.write(bytes,0,len);
            }
                fileInputStream.close();
                outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("文件响应出错，读写出错");
        }

    }


    public static void onlineReader(File file,HttpServletResponse response){
        if (file.exists()){
            byte[] data = null;
            try {
                response.setHeader("Content-Disposition", "inline;fileName=" + URLEncoder.encode(file.getName(), "UTF-8"));
                FileInputStream input = new FileInputStream(file);
                data = new byte[input.available()];
                input.read(data);

                response.getOutputStream().write(data);
                input.close();
            } catch (Exception e) {
                System.out.println(e);
            }

        }else{
            System.out.println("文件不存在");
        }
    }
}
