Java中实现写Word文档

本文主要是介绍Java中实现写Word文档，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

背景：通过java代码，往docx文档中写入标题和段落。

依赖的maven包：

<dependency>        <groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>5.2.2</version>
</dependency>
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>5.2.2</version>
</dependency>
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml-schemas</artifactId><version>4.1.2</version>
</dependency>

创建标题，网上很多文章说使用如下代码可以实现：

            // 创建一个标题XWPFParagraph titleParagraph = document.createParagraph();titleParagraph.setStyle("heading 1");XWPFRun titleRun = titleParagraph.createRun();titleRun.setText("标题测试");titleRun.setBold(true);titleRun.setFontSize(20);

但是打开word后发现标题并没有生效。

这是因为需要自己编写标题的样式信息，参考如下代码中的addCustomHeadingStyle方法。

完整的代码参考如下：

import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.math.BigInteger;
import java.util.Arrays;
import java.util.List;/*** word文档工具类*/
public class DocxUtil {/*** 增加自定义标题样式* @param docxDocument 目标文档* @param strStyleId 样式名称* @param headingLevel 样式级别*/private static void addCustomHeadingStyle(XWPFDocument docxDocument, String strStyleId, int headingLevel) {CTStyle ctStyle = CTStyle.Factory.newInstance();ctStyle.setStyleId(strStyleId);CTString styleName = CTString.Factory.newInstance();styleName.setVal(strStyleId);ctStyle.setName(styleName);CTDecimalNumber indentNumber = CTDecimalNumber.Factory.newInstance();indentNumber.setVal(BigInteger.valueOf(headingLevel));// lower number > style is more prominent in the formats barctStyle.setUiPriority(indentNumber);CTOnOff onoffnull = CTOnOff.Factory.newInstance();ctStyle.setUnhideWhenUsed(onoffnull);// style shows up in the formats barctStyle.setQFormat(onoffnull);// style defines a heading of the given levelCTPPrGeneral ppr = CTPPrGeneral.Factory.newInstance();ppr.setOutlineLvl(indentNumber);ctStyle.setPPr(ppr);XWPFStyle style = new XWPFStyle(ctStyle);// is a null op if already definedXWPFStyles styles = docxDocument.createStyles();style.setType(STStyleType.PARAGRAPH);styles.addStyle(style);}/*** 生成一个标题 + 一个段落格式的docx文档* @param title 标题* @param content 正文* @param filePath docx地址*/public static void generateDocxFile(String title, String content, String filePath){try {// 创建一个新的空白docx文档XWPFDocument document = new XWPFDocument();addCustomHeadingStyle(document, "heading 1", 1);// 创建一个标题XWPFParagraph titleParagraph = document.createParagraph();titleParagraph.setStyle("heading 1");XWPFRun titleRun = titleParagraph.createRun();titleRun.setText(title);titleRun.setBold(true);titleRun.setFontSize(20);// 获取段落的CTPPr对象CTPPr pPr = titleParagraph.getCTP().getPPr();// 如果pPr为null，说明还没有属性，需要创建if (pPr == null) {pPr = titleParagraph.getCTP().addNewPPr();}// 设置文本居中对齐CTJc jc = pPr.isSetJc() ? pPr.getJc() : pPr.addNewJc();jc.setVal(STJc.CENTER); // 居中对齐// 创建一个段落XWPFParagraph paragraph = document.createParagraph();XWPFRun run = paragraph.createRun();run.setText(content);// 写入数据到文档FileOutputStream out = new FileOutputStream(new File(filePath));document.write(out);out.close();}catch (Exception e){e.printStackTrace();}}/*** 生成N个标题 + N个段落格式的docx文档* @param titleList* @param contentList* @param filePath* @throws Exception*/public static void generateDocxFile(List<String> titleList, List<String> contentList, String filePath){if(titleList.size() != contentList.size()){System.out.println("title和content数量不匹配！");}// 创建一个新的空白docx文档XWPFDocument document = new XWPFDocument();addCustomHeadingStyle(document, "heading 1", 1);for(int i = 0; i < titleList.size(); i++){/* -------------创建一个标题 ---------------*/XWPFParagraph titleParagraph = document.createParagraph();titleParagraph.setStyle("heading 1");XWPFRun titleRun = titleParagraph.createRun();titleRun.setText(titleList.get(i));titleRun.setBold(true);titleRun.setFontSize(20);// 获取段落的CTPPr对象CTPPr pPr = titleParagraph.getCTP().getPPr();// 如果pPr为null，说明还没有属性，需要创建if (pPr == null) {pPr = titleParagraph.getCTP().addNewPPr();}// 设置文本居中对齐CTJc jc = pPr.isSetJc() ? pPr.getJc() : pPr.addNewJc();jc.setVal(STJc.CENTER); // 居中对齐/* -------------创建一个段落 ---------------*/XWPFParagraph paragraph = document.createParagraph();XWPFRun run = paragraph.createRun();run.setText(contentList.get(i));}// 写入数据到文档FileOutputStream out = null;try {out = new FileOutputStream(new File(filePath));document.write(out);out.close();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}public static void main(String[] args) {List<String> titleList = Arrays.asList("洗车标题2", "保养标题2");List<String> contentList = Arrays.asList("洗车的操作事项：\n1)好好洗；2)洗干净", "保养的操作事项：\n1)好好保养；2)保养干净");DocxUtil.generateDocxFile(titleList, contentList, "D:\\temp\\example3.docx");}
}

效果如下，标题的属性确实是"标题1"。
