生活随笔收集整理的這篇文章主要介紹了 java生成docx文件、pdf文件、docx转pdf、docx转图片 pdf转图片工具小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

docx4j生成docx文件、pdf文件、docx轉pdf、docx轉圖片 pdf轉圖片工具

最近寫項目時遇到一些操作數據填充word、pdf以及word轉pdf、word轉圖片的需求。網絡搜索資料經整理如下
操作office文檔、pdf一般來說有好幾種實現方式

1、docx4j+apache.pdfbox

1.1 引入maven

<dependency><groupId>org.apache.pdfbox</groupId><artifactId>pdfbox</artifactId><version>2.0.25</version></dependency><dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>org.apache.poi.xwpf.converter.pdf</artifactId><version>1.0.4</version></dependency><dependency><groupId>org.docx4j</groupId><artifactId>docx4j-JAXB-Internal</artifactId><version>8.2.4</version></dependency><dependency><groupId>org.docx4j</groupId><artifactId>docx4j-export-fo</artifactId><version>8.2.4</version></dependency>

-----------坑坑坑坑直接再docx文件中進行修改占位符不一定會連續！！！-----------* ${var}必須是連續的，否則取不到變量。有時候取不到變量的時候可以抓換為xml然后查看你的變量是否是連續的* 可以通過如下方式解決現在docx文件中寫入占位符然后* 把當前docx文件用rar或zip打開，找到其中的 word/document.xml文件，修改占位符連續* <p>* 比如把* <w:r>* <w:t>${na</w:t>* </w:r>* <w:r>* <w:t>me}</w:t>* </w:r>* 修改為* <w:r>* <w:t>${name}</w:t>* </w:r>* 2、全部通過書簽* 3、通過域變量* 通過域變量需要重寫 docx4居中 XmlUtils 工具類中unmarshallFromTemplate方法以適配域變量* 具體目錄在

1.2.1 重寫 XmlUtils以適配域變量

重寫 XmlUtils 工具類中unmarshallFromTemplate方法以適配域變量

1.3 關于模板

1.3.1 新建一個docx文檔如并添加占位符 (不推薦可以全部都是用標簽或域變量)

頭像出需要添加書簽，書簽用以替換圖片

1.3.2 修改占位符使其連續

用zip或rar工具打開docx文檔并找到word/document.xml文件進行編輯

偷偷的告訴你，其實docx文檔也是壓縮包，可以修改其后綴直接變成zip文件

打開document.xml文檔如下發現剛才的占位符是不連續的，我們要修改使其連續

使用編輯器修改后如下，然后把該文件寫會到word問里，或者通過zip工具放進去

現在就可以直接調用工具方法替換數據以及圖片了

1.3.2 使用域變量+書簽（圖片需要使用書簽）

注意使用域變量需要重寫 docx4居中 XmlUtils 工具類中unmarshallFromTemplate方法以適配域變量

2、xdocreport

2.1 引入maven

<dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>fr.opensagres.xdocreport.document.docx</artifactId><version>2.0.2</version></dependency><dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>fr.opensagres.xdocreport.template.freemarker</artifactId><version>2.0.2</version></dependency><dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>fr.opensagres.xdocreport.converter.docx.xwpf</artifactId><version>2.0.2</version></dependency><dependency><groupId>org.apache.pdfbox</groupId><artifactId>pdfbox</artifactId><version>2.0.25</version></dependency><dependency><groupId>fr.opensagres.xdocreport</groupId><artifactId>fr.opensagres.poi.xwpf.converter.pdf</artifactId><version>2.0.2</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency>

2.2 模板

注意如果要動態替換圖片需要先在模板里插入一張圖片，否則無法替換圖片

選中頭像后的圖片

2.3 邏輯代碼

public static void main(String[] args) {Map<String, Object> param = new HashMap<>();param.put("user.username", "小明不怕不怕啦");param.put("user.hobby", "愛玩dota");param.put("name", "sssssssssssssssssssssss");String rootPath = XdocreportUtils.class.getClassLoader().getResource("").getPath();String filePath = String.format("%stemplates/xdocreport/xdocxtemplate.docx", rootPath);Map<String, IImageProvider> imgMap = new HashMap<>();IImageProvider logo = new FileImageProvider(new File("C:\\Users\\Administrator\\Desktop\\2021122211591833953227008.png"), true);logo.setSize(500f, 500f);imgMap.put("logo", logo);IImageProvider pic = new FileImageProvider(new File("C:\\Users\\Administrator\\Desktop\\suoluePic.PNG"), true);pic.setSize(200f, 200f);imgMap.put("pic", pic);exportDocx(param, imgMap, new File(filePath), "C:\\Users\\Administrator\\Desktop\\DocxProjectWithFreemarker_Out.docx");exportPdf(param, imgMap, new File(filePath), "C:\\Users\\Administrator\\Desktop\\DocxProjectWithFreemarker_Out.pdf");}public static void exportDocx(Map<String, Object> param, Map<String, IImageProvider> imgMap, File templateFIle, String outPath) {try {InputStream in = new FileInputStream(templateFIle);//載入模板IXDocReport report = XDocReportRegistry.getRegistry().loadReport(in, TemplateEngineKind.Freemarker);IContext context = report.createContext();//設置要替換的值if (MapUtils.isNotEmpty(param)) {for (Map.Entry<String, Object> entry : param.entrySet()) {context.put(entry.getKey(), entry.getValue());}}FieldsMetadata metadata = report.createFieldsMetadata();report.setFieldsMetadata(metadata);//替換圖片if (MapUtils.isNotEmpty(imgMap)) {for (Map.Entry<String, IImageProvider> entry : imgMap.entrySet()) {context.put(entry.getKey(), entry.getValue());metadata.addFieldAsImage(entry.getKey());}}report.setFieldsMetadata(metadata);OutputStream out = new FileOutputStream(new File(outPath));report.process(context, out);out.close();} catch (IOException e) {log.error("導出docx文件出現異常！", e);} catch (XDocReportException e) {log.error("導出docx文件出現異常！", e);}}public static void exportPdf(Map<String, Object> param, Map<String, IImageProvider> imgMap, File templateFIle, String outPath) {try {InputStream in = new FileInputStream(templateFIle);//載入模板IXDocReport report = XDocReportRegistry.getRegistry().loadReport(in, TemplateEngineKind.Freemarker);IContext context = report.createContext();//設置要替換的值if (MapUtils.isNotEmpty(param)) {for (Map.Entry<String, Object> entry : param.entrySet()) {context.put(entry.getKey(), entry.getValue());}}FieldsMetadata metadata = report.createFieldsMetadata();report.setFieldsMetadata(metadata);//替換圖片if (MapUtils.isNotEmpty(imgMap)) {for (Map.Entry<String, IImageProvider> entry : imgMap.entrySet()) {context.put(entry.getKey(), entry.getValue());metadata.addFieldAsImage(entry.getKey());}}report.setFieldsMetadata(metadata);OutputStream out = new FileOutputStream(new File(outPath));Options options = Options.getTo(ConverterTypeTo.PDF).via(ConverterTypeVia.XWPF);report.convert(context, options, out);out.close();} catch (IOException e) {log.error("導出pdf文件出現異常！", e);} catch (XDocReportException e) {log.error("導出pdf文件出現異常！", e);}}

2.4 效果

3、冰藍科技的Spire

3.1 引入maven配置

<dependency><groupId>e-iceblue</groupId><artifactId>spire.doc.free</artifactId><version>3.9.0</version></dependency><repositories><repository><id>com.e-iceblue</id><url>https://repo.e-iceblue.cn/repository/maven-public/</url></repository></repositories>

3.2 邏輯代碼

import com.spire.doc.Document; import com.spire.doc.FileFormat; import com.spire.doc.documents.BookmarksNavigator; import com.spire.doc.documents.Paragraph; import com.spire.doc.documents.TextBodyPart; import com.spire.doc.fields.DocPicture;import java.io.IOException; import java.util.HashMap; import java.util.Map;public class SpireWordPicTest {public static void main(String[] args) throws IOException {//加載Word文檔Document doc = new Document("C:\\Users\\Administrator\\Desktop\\testDocTemplates.docx");Map<String,String> mappings = new HashMap<>();mappings.put("username","小明");mappings.put("password","123456");/*** https://www.cnblogs.com/Yesi/p/11422349.html* 需要先在模板里設置書簽然后替換**/for(Map.Entry<String,String > entry:mappings.entrySet()){doc.replace(String.format("${%s}",entry.getKey()),entry.getValue(), false, true);}//定位到指定書簽位置設置二維碼BookmarksNavigator bookmarksNavigator = new BookmarksNavigator(doc);bookmarksNavigator.moveToBookmark("headerPng", true, true);Paragraph para= new Paragraph(doc);DocPicture docPicture = para.appendPicture("C:\\Users\\Administrator\\Desktop\\企業微信截圖_20211228152622.png");//設置圖片寬度docPicture.setWidth(110);//設置圖片高度docPicture.setHeight(110);TextBodyPart bodyPart = new TextBodyPart(doc);bodyPart.getBodyItems().add(para);bookmarksNavigator.replaceBookmarkContent(bodyPart);//保存文檔doc.saveToFile("C:\\Users\\Administrator\\Desktop\\ReplaceAllMatchedText.docx", FileFormat.Docx_2013);}

冰藍科技的免費版代碼執行效率很低，不知道正式版怎么樣
https://www.e-iceblue.cn/spiredocforjava/spire-doc-for-java-program-guide-content.html
樣例代碼可參考 https://gitee.com/wahnn/SpringBootAll/tree/master/SpringBoot-xdocreportAndDocx4j
