前言
本文主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
先来看下最后的效果图：
正文
模板配置
先来看下我们的模板：
首先我们需要先在word模板里面设置占位符，这里有一个非常重要的点就是我们是根据${占位符}来替换的，其实word文档本质上就是一个xml文件，因此我们需要保证占位符不被切割，具体做法如下：
1.首先用解压工具打开模板
2.打开document.xml文件
3.可以看出文件并未格式化，我们先格式化代码
4.可以看到我们的占位符被切割了，我们需要干掉中间多余的。
5.点击开始后直接覆盖源文件就可以了，现在可以开始写代码了。
注意要保证我们的每个占位符不被切割，否则是无法进行替换的

</dependency>首先看下我们两个表格的实体类(不一定要给表格建对象，根据个人需求添加即可)
// 家庭成员
@Builder(toBuilder = true)
@Data
@AllArgsConstructor
@NoArgsConstructor
public class EpRewandpun {
private String urewdate;
private String urewunit;
private String urewdesc;
}
// 奖惩情况
@Builder(toBuilder = true)
@Data
@AllArgsConstructor
@NoArgsConstructor
public class EpPmenber {
private String uconnection;
private String uname;
private String ubirthday;
private String uworkunit;
private String uploity;
private String ustatus;
}接着看下我们的测试方法：
@SpringBootTest
class Tests {
@Test
void contextLoads() throws IOException {
String template = "C:UserslikunDesktop员工基本情况表.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("${umajor}", "Java开发");
// 照片路径以及大小
Map<String, Object> phomap = new HashMap<>(8);
phomap.put("width", 100);
phomap.put("height", 130);
phomap.put("type", "png");
phomap.put("content", "E:\\Photo\\头像.jpg");
paramMap.put("${upho}", phomap);
//查询员工家庭信息
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("群众");
pmenber.setUworkunit("广东xxx公司");
pmenber.setUstatus("无");
menberlist.add(pmenber);
}
paramMap.put("menberlist", menberlist);
//查询员工奖励情况
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，先来看下我们的 generateWord 核心方法：
public class WordUtil {
/**
* 根据指定的参数值、模板，生成 word 文档
* 注意：其它模板需要根据情况进行调整
*
* @param param 变量集合
* @param template 模板路径
*/
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) {
// 处理段落
List<XWPFParagraph> paragraphList = doc.getParagraphs();
processParagraphs(paragraphList, param, doc);
// 处理表格
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) {//奖惩情况
if (andpunlist.size() > 0) {
for (int j = 0; j < andpunlist.size() - 1; j++) {
copy(table, row2, size + j);
}
}
}
List<XWPFTableRow> rows = table.getRows();
int _row = 0;
for (XWPFTableRow row : rows) {
List<XWPFTableCell> cells = row.getTableCells();
for (XWPFTableCell cell : cells) {
List<XWPFParagraph> paragraphListTable = cell.getParagraphs();
processParagraphs(paragraphListTable, param, doc);
}
// 家庭成员
if (i == 1 && _row >= size) {
if (menberlist.size() == 0) {
_row++;
continue;
}
row.getCell(0).setText(menberlist.get(_row - size).getUconnection());
row.getCell(1).setText(menberlist.get(_row - size).getUname());
row.getCell(2).setText(menberlist.get(_row - size).getUbirthday());
row.getCell(3).setText(menberlist.get(_row - size).getUploity());
row.getCell(4).setText(menberlist.get(_row - size).getUworkunit());
row.getCell(5).setText(menberlist.get(_row - size).getUstatus());
} else if (i == 2 && _row >= size) {//奖励情况
if (andpunlist.size() == 0) {
_row++;
continue;
}
row.getCell(0).setText(andpunlist.get(_row - size).getUrewdate());
row.getCell(1).setText(andpunlist.get(_row - size).getUrewunit());
row.getCell(2).setText(andpunlist.get(_row - size).getUrewdesc());
}
_row++;
}
i++;
}
}
} catch (Exception e) {
e.printStackTrace();
}
return doc;
}看下我们的 copy 方法，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) {
// 在表格指定位置新增一行
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());
}
}
}接下来是我们的 processParagraphs 方法，用来进行占位符的替换以及头像的插入。
/**
* 处理段落
*/
@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) {
// 处理答案中的回车换行
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 方法，用来插入图片，以及 getPictureType 方法获取图片类型。
/**
* 插入图片
*
*/
private static void insertPicture(XWPFDocument document, String filePath, CTInline inline, int width, int height, XWPFParagraph paragraph) throws Exception {
// 读取图片路径
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);
}
/**
* 根据图片类型，取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;
}
private static String getPicXml(String blipId, int width, int height) {
String picXml = "" + "<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">" + " <a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture">" + " <pic:pic xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture">" + " <pic:nvPicPr>" + " <pic:cNvPr id="" + 0 + "" name="Generated"/>" + " <pic:cNvPicPr/>" + " </pic:nvPicPr>" + " <pic:blipFill>" + " <a:blip r:embed="" + blipId + "" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships"/>" + " <a:stretch>" + " <a:fillRect/>" + " </a:stretch>" + " </pic:blipFill>" + " <pic:spPr>" + " <a:xfrm>"
+ " <a:off x="0" y="0"/>" + " <a:ext cx="" + width + "" cy="" + height + ""/>" + " </a:xfrm>" + " <a:prstGeom prst="rect">" + " <a:avLst/>" + " </a:prstGeom>" + " </pic:spPr>" + " </pic:pic>" + " </a:graphicData>" + "</a:graphic>";
return picXml;
}最后填充就是这个样子：
word转pdf
最后在补充一个知识点，有时候会需要我们把 word 文档转成 pdf，其实用的是收费插件 aspose-words，在文末有github地址，我已经把插件放到doc目录下，有需要可自行下载。
<!-- 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 收费插件windows linux下均可用
*
* @param inPath
* 源文件路径
* @param outPath
* 输出文件路径
*/
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);
// 另外服务器需要上传中文字体到/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);
// 全面支持DOC, DOCX, OOXML, RTF HTML,OpenDocument, PDF,EPUB, XPS, SWF 相互转换
doc.save(os, SaveFormat.PDF);
os.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}注意：Linux服务器上需要上传中文字体，用法也很简单，只要传入word文档路径和要生成的pdf路径就可以了。
String wordPath = "C:Users\\likun\\Desktop\\人员基本情况.docx";
String pdfPath = "C:Users\\likun\\Desktop\\人员基本情况.pdf";
AsposeWordUtil.convertPdfToDocx(wordPath, pdfPath);效果图：
总结
