itextpdf实现word模板生成文件

前言

使用word模板生成文件，如下图，将左侧的模板生成为右侧的填充word文档。

操作方式

1. 引入依赖

		 <!-- https://mvnrepository.com/artifact/com.itextpdf/itextpdf --><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.13.3</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-excelant</artifactId><version>4.1.2</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-examples</artifactId><version>4.1.2</version></dependency>

2. 创建模板，创建一份template2.docx文件，内容如下
   
3. 编写代码

package com.csair.jasypt.myjaspyt.util;import org.apache.poi.util.Units;
import org.apache.poi.xwpf.usermodel.*;import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.util.Iterator;
import java.util.List;
import java.util.Map;public class DocxUtil {public static void parseDocTemplate(String sourcePath, String targetPath, Map<String, Object> data, Map<String, Object> picData) {try {FileInputStream is = new FileInputStream(sourcePath);XWPFDocument document = new XWPFDocument(is);if (data.size() > 0) {changeText(document, data);changeTableText(document, data);}if (picData.size() > 0) {changePic(document, picData);changeTablePic(document, picData);}FileOutputStream out = new FileOutputStream(targetPath);document.write(out);} catch (FileNotFoundException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();}}public static void changeText(XWPFDocument document, Map<String, Object> textMap) {// 获取段落集合Iterator<XWPFParagraph> iterator = document.getParagraphsIterator();XWPFParagraph paragraph = null;while (iterator.hasNext()) {paragraph = iterator.next();// 判断此段落是否需要替换if (checkText(paragraph.getText())) {replaceValue(paragraph, textMap);}}}public static boolean checkText(String text) {boolean check = false;if (text.contains("$")) {check = true;}return check;}public static void changePic(XWPFDocument document, Map<String, Object> picData) throws Exception {// 获取段落集合Iterator<XWPFParagraph> iterator = document.getParagraphsIterator();XWPFParagraph paragraph;while (iterator.hasNext()) {paragraph = iterator.next();// 判断此段落是否需要替换String text = paragraph.getText();if (checkText(text)) {replacePicValue(paragraph, picData);}}}public static void changeTableText(XWPFDocument document, Map<String, Object> data) {// 获取文件的表格Iterator<XWPFTable> tableList = document.getTablesIterator();XWPFTable table;List<XWPFTableRow> rows;List<XWPFTableCell> cells;// 循环所有需要进行替换的文本，进行替换while (tableList.hasNext()) {table = tableList.next();if (checkText(table.getText())) {rows = table.getRows();// 遍历表格，并替换模板for (XWPFTableRow row : rows) {cells = row.getTableCells();for (XWPFTableCell cell : cells) {// 判断单元格是否需要替换if (checkText(cell.getText())) {List<XWPFParagraph> paragraphs = cell.getParagraphs();for (XWPFParagraph paragraph : paragraphs) {replaceValue(paragraph, data);}}}}}}}public static void changeTablePic(XWPFDocument document, Map<String, Object> picData) throws Exception {// 获取文件的表格Iterator<XWPFTable> tableList = document.getTablesIterator();XWPFTable table;List<XWPFTableRow> rows;List<XWPFTableCell> cells;// 循环所有需要进行替换的文本，进行替换while (tableList.hasNext()) {table = tableList.next();if (checkText(table.getText())) {rows = table.getRows();// 遍历表格，并替换模板for (XWPFTableRow row : rows) {cells = row.getTableCells();for (XWPFTableCell cell : cells) {// 判断单元格是否需要替换if (checkText(cell.getText())) {List<XWPFParagraph> paragraphs = cell.getParagraphs();for (XWPFParagraph paragraph : paragraphs) {replacePicValue(paragraph, picData);}}}}}}}public static void replaceValue(XWPFParagraph paragraph, Map<String, Object> textMap) {XWPFRun run, nextRun;String runsText;List<XWPFRun> runs = paragraph.getRuns();for (int i = 0; i < runs.size(); i++) {run = runs.get(i);runsText = run.getText(0);if (runsText.contains("${") || (runsText.contains("$") && runs.get(i + 1).getText(0).substring(0, 1).equals("{"))) {while (!runsText.contains("}")) {nextRun = runs.get(i + 1);runsText = runsText + nextRun.getText(0);//删除该节点下的数据paragraph.removeRun(i + 1);}Iterator<Map.Entry<String, Object>> iterator = textMap.entrySet().iterator();while (iterator.hasNext()) {Map.Entry<String, Object> entry = iterator.next();String key = entry.getKey();Object obj = entry.getValue();if (runsText.contains(key) && null != obj) {runsText = runsText.replace(key, obj + "");}}run.setText(runsText, 0);}}}public static void replacePicValue(XWPFParagraph paragraph, Map<String, Object> picData) throws Exception {List<XWPFRun> runs = paragraph.getRuns();for (XWPFRun run : runs) {String str = run.toString();Iterator<Map.Entry<String, Object>> it = picData.entrySet().iterator();while (it.hasNext()) {Map.Entry<String, Object> entry = it.next();String key = entry.getKey();Object obj = entry.getValue();int idx = str.indexOf(key);if (idx > -1) {run.setText("", 0);FileInputStream is = new FileInputStream((String) obj);// 图片宽度、高度int width = Units.toEMU(100), height = Units.toEMU(100);// 添加图片信息，段落高度需要在模板中自行调整run.addPicture(is, XWPFDocument.PICTURE_TYPE_PNG, (String) obj, width, height);}}}}
}

4. 编写测试用例,并执行测试用例

 @Testvoid testWord() throws Exception {Map<String, Object> data = new HashMap<>();Map<String, Object> picData = new HashMap<>();data.put("${year}", "2023");data.put("${month}", "06");data.put("${date}", "20");data.put("${birthday}", "2000年6月11日");data.put("${name}", "王小鱼");data.put("${sex}", "女");data.put("${address}", "北京市朝阳区光明街道幸福小区301号");data.put("${phoneno}", "1380000000");picData.put("${pic}", "D:\\test\\dog.jpg");DocxUtil.parseDocTemplate("D:\\test\\template2.docx","D:\\test\\template2_out.docx",data,picData);System.out.println("----------------end---------------");}

生成得到被填充出来的文件。
