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>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
@NoArgsConstructor
public class EpRewandpun {
private String urewdate;
private String urewunit;
private String urewdesc;
}
// 奖惩状况
@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;
}接着看下咱们的测试方法：
@SpringBootTest
class 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。
