一、通过aspose-words将word，Excel文档转为PDF

1.1 引入相关的jar

word转pdf需要引入 aspose-words-15.8.0-jdk16.jar

下载JAR包

Word

/noteshare?id=1e73ab1c91abad338271d50a881165c2

excel转pdf需要引入aspose-cells-8.5.2.jar

Excel

/noteshare?id=f75d87445106ea6ca6b54cfa58bc4fb2

1.2 将两个jar包，放入项目resources/lib目录下

在项目resouces目录下，新建一个lib的package，然后将下载的jar包放入其中。

1.3 配置pom.xml

<dependency><groupId>com.aspose</groupId><artifactId>words</artifactId><!--version，在本地跑项目时，不加不会报错，但是通过jenkins可持续集成构建时，需加version--><!--version可以随便指定，因为下面指定了该依赖是从项目之中加载，不从maven仓库下载--><!--jenkins可持续集成发布时，会更新依赖，若不指定version会报错--><version>1.0</version><scope>system</scope><systemPath>${basedir}/src/main/resources/lib/aspose-words.jar</systemPath></dependency><dependency><groupId>com.aspose</groupId><artifactId>cells</artifactId><version>1.0</version><scope>system</scope><systemPath>${basedir}/src/main/resources/lib/aspose-cells-8.5.2.jar</systemPath></dependency>

这样操作完成后，经测试运行，在本地调试好使，但是放在linux服务器上时，会出现依赖找不到的错误，故还需要在Maven打包的时候，将项目里的两个依赖也打进包之中。

<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><!-- 将项目本地依赖也打包在项目之中 --><includeSystemScope>true</includeSystemScope></configuration></plugin></plugins></build>

1.4 测试代码

package com.test;import java.io.File;import java.io.FileOutputStream;import java.io.InputStream;import com.aspose.cells.Workbook;import com.aspose.words.Document;import com.aspose.words.License;/*** Word或Excel 转Pdf 帮助类* @author lenovo* 备注:需要引入 aspose-words-15.8.0-jdk16.jar / aspose-cells-8.5.2.jar*/public class PdfUtil {private static boolean getLicense() {boolean result = false;try {InputStream is = PdfUtil.class.getClassLoader().getResourceAsStream("license.xml"); // license.xml应放在..\WebRoot\WEB-INF\classes路径下License aposeLic = new License();aposeLic.setLicense(is);result = true;} catch (Exception e) {e.printStackTrace();}return result;}/*** @param wordPath 需要被转换的word全路径带文件名* @param pdfPath 转换之后pdf的全路径带文件名*/public static void doc2pdf(String wordPath, String pdfPath) {if (!getLicense()) {// 验证License 若不验证则转化出的pdf文档会有水印产生return;}try {long old = System.currentTimeMillis();File file = new File(pdfPath); //新建一个pdf文档FileOutputStream os = new FileOutputStream(file);Document doc = new Document(wordPath); //Address是将要被转化的word文档doc.save(os, com.aspose.words.SaveFormat.PDF);//全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB, XPS, SWF 相互转换long now = System.currentTimeMillis();os.close();System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); //转化用时} catch (Exception e) {e.printStackTrace();}}/*** @param excelPath 需要被转换的excel全路径带文件名* @param pdfPath 转换之后pdf的全路径带文件名*/public static void excel2pdf(String excelPath, String pdfPath) {if (!getLicense()) {// 验证License 若不验证则转化出的pdf文档会有水印产生return;}try {long old = System.currentTimeMillis();Workbook wb = new Workbook(excelPath);// 原始excel路径FileOutputStream fileOS = new FileOutputStream(new File(pdfPath));wb.save(fileOS, com.aspose.cells.SaveFormat.PDF);fileOS.close();long now = System.currentTimeMillis();System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); //转化用时} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {//word 和excel 转为pdfString filePaths="D:/t.docx";String fileName="zsqexcel78";String pdfPath="D:/t.pdf";// doc2pdf(filePaths, pdfPath);//filePaths需要转换的文件位置 pdfPath为存储位置String excel2pdf="D:/t.xlsx";excel2pdf(excel2pdf,pdfPath);} }

二、记录下JAVA LINUX，WORD转PDF，用Documents4j

2.1 添加依赖

<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>

这个有可能会存在guava包冲突的情况，spring cloud 里面也引用了guava，启动项目若报guava有关的错误，解决下依赖冲突即可。

我通过下面exclustions排除依赖时，一直不成功

<exclusions><exclusion>.....guava</exclusion></exclusions>

故，后来直接在里面重新添加了guava依赖，指定版本为20，成功解决问题。

2.2 word转pdf实践代码

import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import com.documents4j.api.DocumentType;import com.documents4j.api.IConverter;import com.documents4j.job.LocalConverter;public class Document4jApp {public static void main(String[] args) {File inputWord = new File("C:/Users/avijit.shaw/Desktop/testing/docx/Account Opening Prototype Details.docx");File outputFile = new File("Test_out.pdf");try {InputStream docxInputStream = new FileInputStream(inputWord);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build(); converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();outputStream.close();System.out.println("success");} catch (Exception e) {e.printStackTrace();}}

三、java 文件转成pdf文件 预览

3.1 前端代码

//预览功能preview: function () {//判断选中状态var ids ="";var num = 0;$(".checkbox").each(function () {if($(this).is(':checked')){ids +=$(this).val() + ",";num++;}});if(num <=0 ){toastr.error('请选择需要预览的文件！');return;}if(num > 1){toastr.error('页面下载只支持单个文件预览！');return;}ids = ids.slice(0,ids.length-1);$.ajax({type: "post",url: backbasePath+'/apia/v1/file/queryById',dataType:"json",data:{token:$("#token").val(),id:ids,},success: function(data) {if('000000'==data.code){// 文件路径var path=data.data.file_path;// 文件名称var fileName=data.data.file_name;// 获取文件后缀名var suffix=fileName.substring(fileName.lastIndexOf(".")+1);//如果对应的是文档if(suffix == 'doc' || suffix == 'docx' || suffix == 'txt'|| suffix == 'pdf'){//打开跳转页面window.open(frontTemplatesPath + 'previewFile.html?suffix='+suffix+'&path='+path+'&fileName='+fileName,"_blank");} else{toastr.error('当前文件类型暂不支持预览！');}} else if (('900000' == data.code) || ('999999'== data.code)) {toastr.error('查询文件信息失败！');} else {toastr.error(data.msg);}},error: function () {toastr.error('查询文件信息失败！');}});},

3.2 html

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>文件预览界面</title></head><body><div class="container"><div><div ><iframe style="width: 100%;height: 1000px;" src="" id="pdf"></iframe></div></div></div></body></html><script src="/coalminehwaui/static/js/jquery-3.1.1.min.js"></script><script src="/coalminehwaui/static/js/project/common.js"></script><script src="/coalminehwaui/static/js/plugins/toastr/toastr.min.js"></script><!-- slimscroll把任何div元素包裹的内容区加上具有好的滚动条--><script src="/coalminehwaui/static/js/plugins/slimscroll/jquery.slimscroll.min.js"></script><script>'use strict';$(function () {LookPlan.getUrlString();LookPlan.init();});var LookPlan = new Object({getUrlString:function(name){var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");var r = window.location.search.substr(1).match(reg);if (r != null) return unescape(r[2]);return '';},init:function() {var suffix =LookPlan.getUrlString('suffix');var path =LookPlan.getUrlString('path');var fileName =LookPlan.getUrlString('fileName');var src=backbasePath + '/apia/v1/file/previewFile?path='+path+'&fileName='+fileName+'&suffix='+suffix;setTimeout(function () {document.getElementById("pdf").src=src;}, 500);}});</script>

3.3 后端代码

<!-- 文件转换成pdf--> <dependency><groupId>com.documents4j</groupId><artifactId>documents4j-local</artifactId><version>1.1.1</version> </dependency> <dependency><groupId>com.documents4j</groupId><artifactId>documents4j-transformer-msoffice-word</artifactId><version>1.1.1</version> </dependency>import com.documents4j.api.DocumentType;import com.documents4j.api.IConverter;import com.documents4j.job.LocalConverter;/*** 文档文件预览*/@RequestMapping(path = "/previewFile")public void preview(HttpServletResponse response, @RequestParam(required = true)String path, @RequestParam(required = true)String fileName, @RequestParam(required = true)String suffix) throws Exception {// 读取pdf文件的路径String pdfPath="";// 将对应的后缀转换成小写String lastSuffix=suffix.toLowerCase();//读取文件内容,获取文件存储的路径String orgPath = filePath + path;// 生成pdf文件的路径String toPath = filePath + "pdf/";// 判断对应的pdf是否存在，不存在则创建File folder = new File(toPath);if (!folder.exists()) {folder.mkdirs();}// doc类型if (lastSuffix.equals("pdf")) {// pdf 文件不需要转换，直接从上传文件路径读取即可pdfPath=orgPath;} else {// 转换之后的pdf文件String newName=fileName.replace(lastSuffix,"pdf");;File newFile = new File( toPath+"/"+newName);// 如果转换之后的文件夹中有转换后的pdf文件，则直接从里面读取即可if (newFile.exists()) {pdfPath =toPath+"/"+newName;}else {pdfPath = wordToPdf(fileName,orgPath, toPath,lastSuffix);}}// 读取文件流上FileInputStream fis = new FileInputStream(pdfPath);//设置返回的类型response.setContentType("application/pdf");//得到输出流，其实就是发送给客户端的数据。OutputStream os = response.getOutputStream();try {int count = 0;//fis.available()返回文件的总字节数byte[] buffer = new byte[fis.available()];//read(byte[] b)方法一次性读取文件全部数据。while ((count = fis.read(buffer)) != -1)os.write(buffer, 0, count);os.flush();} catch (IOException e) {e.printStackTrace();} finally {if (os != null)os.close();if (fis != null)fis.close();}}

/*** 将之前对应的word文件转换成pdf，然后预览pdf文件*/public String wordToPdf(String orgFile,String orgPath, String toPath, String suffix ){// 转换之后的pdf文件String targetFile=orgFile.replace(suffix,"pdf");File inputWord = new File(orgPath);File outputFile = new File(toPath+targetFile);try {InputStream docxInputStream = new FileInputStream(inputWord);OutputStream outputStream = new FileOutputStream(outputFile);IConverter converter = LocalConverter.builder().build();if(suffix.equals("doc")){converter.convert(docxInputStream).as(DocumentType.DOC).to(outputStream).as(DocumentType.PDF).execute();} else if(suffix.equals("docx")){converter.convert(docxInputStream).as(DocumentType.DOCX).to(outputStream).as(DocumentType.PDF).execute();} else if(suffix.equals("txt")){converter.convert(docxInputStream).as(DocumentType.TEXT).to(outputStream).as(DocumentType.PDF).execute();}outputStream.close();} catch (Exception e) {e.printStackTrace();}return toPath+targetFile;}

四、用java实现word文档转pdf

使用工具（Jar包）

aspose-words-15.11.0.jar（用于PDF转换 ）

public static void main(String[] args) {doc2pdf("/Users/lzl/Desktop/a.docx","/Users/lzl/Desktop/test.pdf");}public static void doc2pdf(String inPath, String outPath) {FileOutputStream os =null;try {File file = new File(outPath); // 新建一个空白pdf文档os = new FileOutputStream(file);Document doc = new Document(inPath); // Address是将要被转化的word文档//insertWatermarkText(doc, "四叶草的诗雨");doc.save(os, SaveFormat.PDF);} catch (Exception e) {e.printStackTrace();}finally{if(os!=null){try {os.close();} catch (IOException e) {e.printStackTrace();}}}}

加水印（升级版）

private static void insertWatermarkText(Document doc, String watermarkText) throws Exception{Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);//水印内容watermark.getTextPath().setText(watermarkText);//水印字体watermark.getTextPath().setFontFamily("宋体");//水印宽度watermark.setWidth(500);//水印高度watermark.setHeight(100);//旋转水印watermark.setRotation(-40);//水印颜色watermark.getFill().setColor(Color.lightGray);watermark.setStrokeColor(Color.lightGray);watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);watermark.setWrapType(WrapType.NONE);watermark.setVerticalAlignment(VerticalAlignment.CENTER);watermark.setHorizontalAlignment(HorizontalAlignment.CENTER);Paragraph watermarkPara = new Paragraph(doc);watermarkPara.appendChild(watermark);for (Section sect : doc.getSections()){insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_PRIMARY);insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_FIRST);insertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HEADER_EVEN);}System.out.println("Watermark Set");}private static void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception{HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);if (header == null){header = new HeaderFooter(sect.getDocument(), headerType);sect.getHeadersFooters().add(header);}header.appendChild(watermarkPara.deepClone(true));}
