前言
本文次要有以下几个知识点：
占位符填充头像导出表格填充word转pdf
先来看下最初的效果图：
注释
模板配置
先来看下咱们的模板：
首先咱们须要先在word模板外面设置占位符，这里有一个十分重要的点就是咱们是依据${占位符}来替换的，其实word文档实质上就是一个xml文件，因而咱们须要保障占位符不被切割，具体做法如下：
1.首先用解压工具关上模板
2.关上document.xml文件
3.能够看出文件并未格式化，咱们先格式化代码
4.能够看到咱们的占位符被切割了，咱们须要干掉两头多余的。
5.点击开始后间接笼罩源文件就能够了，当初能够开始写代码了。
留神要保障咱们的每个占位符不被切割，否则是无奈进行替换的

<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.1.2</version></dependency><dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-scratchpad</artifactId> <version>4.1.2</version></dependency><dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.2</version></dependency>首先看下咱们两个表格的实体类(不肯定要给表格建对象，依据集体需要增加即可)
// 家庭成员@Builder(toBuilder = true)@Data@AllArgsConstructor@NoArgsConstructorpublic class EpRewandpun { private String urewdate; private String urewunit; private String urewdesc;}// 奖惩状况@Builder(toBuilder = true)@Data@AllArgsConstructor@NoArgsConstructorpublic class EpPmenber { private String uconnection; private String uname; private String ubirthday; private String uworkunit; private String uploity; private String ustatus;}接着看下咱们的测试方法：
@SpringBootTestclass Tests { @Test void contextLoads() throws IOException { String template = "C:UserslikunDesktop员工根本情况表.docx"; Map<String, Object> paramMap = new HashMap<>(); paramMap.put("${uname}", "乌龟"); paramMap.put("${usex}", "男"); paramMap.put("${ubirthdate}", "1998年10月22日"); paramMap.put("${unation}", "汉族"); paramMap.put("${unative}", "广东深圳"); paramMap.put("${uplace}", "广东汕头"); paramMap.put("${upolity}", "团员"); paramMap.put("${uworkdate}", "2020年3月16日"); paramMap.put("${uhealth}", "良好"); paramMap.put("${umajorpost}", "软件开发"); paramMap.put("${umajor}", "Java开发"); // 照片门路以及大小 Map<String, Object> phomap = new HashMap<>(8); phomap.put("width", 100); phomap.put("height", 130); phomap.put("type", "png"); phomap.put("content", "E:\\Photo\\头像.jpg"); paramMap.put("${upho}", phomap); //查问员工家庭信息 List<EpPmenber> menberlist = new ArrayList<>(); for (int i = 1; i < 3; i++) { EpPmenber pmenber = new EpPmenber(); pmenber.setUname("小王"); pmenber.setUconnection("父亲"); pmenber.setUbirthday("1962年10月2日"); pmenber.setUploity("大众"); pmenber.setUworkunit("广东xxx公司"); pmenber.setUstatus("无"); menberlist.add(pmenber); } paramMap.put("menberlist", menberlist); //查问员工处分状况 List<EpRewandpun> andpunlist = new ArrayList<>(); for (int i = 1; i < 3; i++) { EpRewandpun rewandpun = new EpRewandpun(); rewandpun.setUrewdate("2020年5月1日"); rewandpun.setUrewunit("深圳xxx有限公司"); rewandpun.setUrewdesc("无"); andpunlist.add(rewandpun); } paramMap.put("andpunlist", andpunlist); // 模板填充 XWPFDocument doc = WordUtil.generateWord(paramMap, template); FileOutputStream fopts = new FileOutputStream("C:Users\\likun\\Desktop\\模板填充.docx"); doc.write(fopts); fopts.close(); }}代码比较简单不再细说，先来看下咱们的 generateWord 外围办法：
public class WordUtil { /** * 依据指定的参数值、模板，生成 word 文档 * 留神：其它模板须要依据状况进行调整 * * @param param 变量汇合 * @param template 模板门路 */ public static XWPFDocument generateWord(Map<String, Object> param, String template) { XWPFDocument doc = null; try { OPCPackage pack = POIXMLDocument.openPackage(template); doc = new XWPFDocument(pack); if (param != null && param.size() > 0) { // 解决段落 List<XWPFParagraph> paragraphList = doc.getParagraphs(); processParagraphs(paragraphList, param, doc); // 解决表格 Iterator<XWPFTable> it = doc.getTablesIterator(); //表格索引 int i = 0; List<EpPmenber> menberlist = (List<EpPmenber>) param.get("menberlist"); List<EpRewandpun> andpunlist = (List<EpRewandpun>) param.get("andpunlist"); while (it.hasNext()) { XWPFTable table = it.next(); int size = table.getRows().size() - 1; XWPFTableRow row2 = table.getRow(size); if (i == 1) {//家庭成员 if (menberlist.size() > 0) { for (int j = 0; j < menberlist.size() - 1; j++) { copy(table, row2, size + j); } } } else if (i == 2) {//奖惩状况 if (andpunlist.size() > 0) { for (int j = 0; j < andpunlist.size() - 1; j++) { copy(table, row2, size + j); } } } _row++; } i++; } } } catch (Exception e) { e.printStackTrace(); } return doc; } }看下咱们的 copy 办法，用来拷贝行属性进行对表格进行复制
/** * 拷贝赋值行 * */public static void copy(XWPFTable table, XWPFTableRow sourceRow, int rowIndex) { // 在表格指定地位新增一行 XWPFTableRow targetRow = table.insertNewTableRow(rowIndex); // 复制行属性 targetRow.getCtRow().setTrPr(sourceRow.getCtRow().getTrPr()); List<XWPFTableCell> cellList = sourceRow.getTableCells(); if (null == cellList) { return; } // 复制列及其属性和内容 XWPFTableCell targetCell = null; for (XWPFTableCell sourceCell : cellList) { targetCell = targetRow.addNewTableCell(); // 列属性 targetCell.getCTTc().setTcPr(sourceCell.getCTTc().getTcPr()); // 段落属性 if (sourceCell.getParagraphs() != null && sourceCell.getParagraphs().size() > 0) { targetCell.getParagraphs().get(0).getCTP().setPPr(sourceCell.getParagraphs().get(0).getCTP().getPPr()); if (sourceCell.getParagraphs().get(0).getRuns() != null && sourceCell.getParagraphs().get(0).getRuns().size() > 0) { XWPFRun cellR = targetCell.getParagraphs().get(0).createRun(); cellR.setText(sourceCell.getText()); cellR.setBold(sourceCell.getParagraphs().get(0).getRuns().get(0).isBold()); } else { targetCell.setText(sourceCell.getText()); } } else { targetCell.setText(sourceCell.getText()); } }}接下来是咱们的 processParagraphs 办法，用来进行占位符的替换以及头像的插入。
/** * 解决段落 */@SuppressWarnings({"unused", "rawtypes"})public static void processParagraphs(List<XWPFParagraph> paragraphList, Map<String, Object> param, XWPFDocument doc) throws InvalidFormatException, IOException { if (paragraphList != null && paragraphList.size() > 0) { for (XWPFParagraph paragraph : paragraphList) { List<XWPFRun> runs = paragraph.getRuns(); for (XWPFRun run : runs) { String text = run.getText(0); if (text != null) { boolean isSetText = false; for (Entry<String, Object> entry : param.entrySet()) { String key = entry.getKey(); if (text.contains(key)) { isSetText = true; Object value; if (entry.getValue() != null) { value = entry.getValue(); } else { value = ""; } // 文本替换 if (value instanceof String) { // 解决答案中的回车换行 if (((String) value).contains("n")) { String[] lines = ((String) value).split("n"); if (lines.length > 0) { text = text.replace(key, lines[0]); for (int j = 1; j < lines.length; j++) { run.addCarriageReturn(); run.setText(lines[j]); } } } else { text = text.replace(key, value.toString()); } } else if (value instanceof Map) { // 图片替换 text = text.replace(key, ""); Map pic = (Map) value; int width = Integer.parseInt(pic.get("width").toString()); int height = Integer.parseInt(pic.get("height").toString()); int picType = getPictureType(pic.get("type").toString()); String byteArray = (String) pic.get("content"); CTInline inline = run.getCTR().addNewDrawing().addNewInline(); //插入图片 insertPicture(doc, byteArray, inline, width, height, paragraph); } } } if (isSetText) { run.setText(text, 0); } } } } }}接下来是 insertPicture 办法，用来插入图片，以及 getPictureType 办法获取图片类型。
/** * 插入图片 * */ private static void insertPicture(XWPFDocument document, String filePath, CTInline inline, int width, int height, XWPFParagraph paragraph) throws Exception { // 读取图片门路 InputStream inputStream = new FileInputStream(new File(filePath));; document.addPictureData(inputStream, XWPFDocument.PICTURE_TYPE_PNG); int id = document.getAllPictures().size() - 1; final int emu = 9525; width *= emu; height *= emu; String blipId = paragraph.getDocument().getRelationId(document.getAllPictures().get(id)); String picXml = getPicXml(blipId, width, height); XmlToken xmlToken = null; try { xmlToken = XmlToken.Factory.parse(picXml); } catch (XmlException xe) { xe.printStackTrace(); } inline.set(xmlToken); inline.setDistT(0); inline.setDistB(0); inline.setDistL(0); inline.setDistR(0); CTPositiveSize2D extent = inline.addNewExtent(); extent.setCx(width); extent.setCy(height); CTNonVisualDrawingProps docPr = inline.addNewDocPr(); docPr.setId(id); docPr.setName("IMG_" + id); docPr.setDescr("IMG_" + id); } /** * 依据图片类型，获得对应的图片类型代码 * * @param picType * @return int */ private static int getPictureType(String picType) { int res = XWPFDocument.PICTURE_TYPE_PICT; if (picType != null) { if ("png".equalsIgnoreCase(picType)) { res = XWPFDocument.PICTURE_TYPE_PNG; } else if ("dib".equalsIgnoreCase(picType)) { res = XWPFDocument.PICTURE_TYPE_DIB; } else if ("emf".equalsIgnoreCase(picType)) { res = XWPFDocument.PICTURE_TYPE_EMF; } else if ("jpg".equalsIgnoreCase(picType) || "jpeg".equalsIgnoreCase(picType)) { res = XWPFDocument.PICTURE_TYPE_JPEG; } else if ("wmf".equalsIgnoreCase(picType)) { res = XWPFDocument.PICTURE_TYPE_WMF; } } return res;}最初填充就是这个样子：
word转pdf
最初在补充一个知识点，有时候会须要咱们把 word 文档转成 pdf，其实网上是有一个免费插件 `aspose-words，具体如何破解请上网搜查，首先导入包：
<!-- Word文档转换 --><dependency> <groupId>com.aspose.words</groupId> <artifactId>aspose-words-jdk16</artifactId> <version>16.4.0</version></dependency>接下来看下代码：
public class AsposeWordUtil { private static final String WIN = "win"; /** * word转pdf 需引入 aspose-words-16.4.0-jdk16.jar包 免费插件windows linux下均可用 * * @param inPath * 源文件门路 * @param outPath * 输入文件门路 */ public static void convertPdfToDocx(String inPath, String outPath) { try { FontSettings fontSettings = new FontSettings(); File file = new File(outPath); FileOutputStream os = new FileOutputStream(file); Document doc = new Document(inPath); // 另外服务器须要上传中文字体到/usr/share/fonts目录（复制windowsC:WindowsFonts目录下的字体文件即可） String cos = System.getProperty("os.name"); if (cos.toLowerCase().startsWith(WIN)) { // windows环境 fontSettings.setFontsFolder("C:/Windows/Fonts", false); } else { // Linux环境 fontSettings.setFontsFolder("/usr/share/fonts", false); } doc.setFontSettings(fontSettings); // 全面反对DOC, DOCX, OOXML, RTF HTML,OpenDocument, PDF,EPUB, XPS, SWF 互相转换 doc.save(os, SaveFormat.PDF); os.close(); } catch (Exception e) { e.printStackTrace(); } }}留神：Linux服务器上须要上传中文字体，用法也很简略，只有传入word文档门路和要生成的pdf门路就能够了。
String wordPath = "C:Users\\likun\\Desktop\\人员根本状况.docx";String pdfPath = "C:Users\\likun\\Desktop\\人员根本状况.pdf";AsposeWordUtil.convertPdfToDocx(wordPath, pdfPath);效果图：
总结
代码写到这里也就完结了，大伙可依据业务需要自行进行调整，如果有什么不对的中央请多多指教。
