模板制作

制作word模版，${xxxx}是要替换的内容。注意${xxxx}是一个整体，中间不能断开，因为利用POI的API程序操作时，判断是否有这个${xxxx}才进行替换。

操作docx文件

POI在读写word docx文件时是通过xwpf模块来进行的，其核心是XWPFDocument。一个XWPFDocument代表一个docx文档，其可以用来读docx文档，也可以用来写docx文档。XWPFDocument中主要包含下面这几种对象：

• XWPFParagraph：代表一个段落。
• XWPFRun：代表具有相同属性的一段文本。
• XWPFTable：代表一个表格。
• XWPFTableRow：表格的一行。
• XWPFTableCell：表格对应的一个单元格

具体代码：

/**  * 根据指定的参数值、模板，生成 word 文档  * @param param 需要替换的变量，key值与模板里${xxxx}的xxx一样  * @param template 模板,docx文档  */  public CustomXWPFDocument generateWord(Map param, String template) { CustomXWPFDocument doc = null;  try {  OPCPackage pack = POIXMLDocument.openPackage(template);  doc = new CustomXWPFDocument(pack);  if (param != null && param.size() > 0) { //处理段落  List paragraphList = doc.getParagraphs();  processParagraphs(paragraphList, param, doc);   //处理表格  Iterator it = doc.getTablesIterator();  while (it.hasNext()) {  XWPFTable table = it.next();  List rows = table.getRows(); for (XWPFTableRow row : rows) { List cells = row.getTableCells(); for (XWPFTableCell cell : cells) {  List paragraphListTable = cell.getParagraphs();  processParagraphs(paragraphListTable, param, doc);  }  }  }  }  } catch (Exception e) {  e.printStackTrace();  }  return doc;  }

/**  * 处理段落  * @param paragraphList  */  public void processParagraphs(List paragraphList,Map param,CustomXWPFDocument doc){ if(paragraphList != null && paragraphList.size() > 0){  for(XWPFParagraph paragraph : paragraphList){ List runs = paragraph.getRuns();  for (XWPFRun run : runs) {  String text = run.getText(0);  if(text != null){  boolean isSetText = false;  for (Entry entry : param.entrySet()) {  String key = "${"+ entry.getKey() +"}"; if(text.indexOf(key) != -1){ isSetText = true;  Object value = entry.getValue();  if (value instanceof String) {//文本替换  text = text.replace(key, value.toString());  //System.out.println(text); } else if (value instanceof Double) { 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());  byte[] byteArray = (byte[]) pic.get("content");  ByteArrayInputStream byteInputStream = new ByteArrayInputStream(byteArray);  try {  String ind = doc.addPictureData(byteInputStream, picType); int id = doc.getNextPicNameNumber(picType); createPicture(id, ind, width , height, run); //System.out.println("图片替换"); } catch (Exception e) {  e.printStackTrace();  }  }  }  }  if(isSetText){  run.setText(text,0);  }  }  }  }  }  }

/**  * 根据图片类型，取得对应的图片类型代码  * @param picType  * @return int  */  private int getPictureType(String picType){ int res = CustomXWPFDocument.PICTURE_TYPE_PICT;  if(picType != null){  if(picType.equalsIgnoreCase("png")){  res = CustomXWPFDocument.PICTURE_TYPE_PNG; }else if(picType.equalsIgnoreCase("dib")){  res = CustomXWPFDocument.PICTURE_TYPE_DIB;  }else if(picType.equalsIgnoreCase("emf")){  res = CustomXWPFDocument.PICTURE_TYPE_EMF;  }else if(picType.equalsIgnoreCase("jpg") || picType.equalsIgnoreCase("jpeg")){  res = CustomXWPFDocument.PICTURE_TYPE_JPEG;  }else if(picType.equalsIgnoreCase("wmf")){  res = CustomXWPFDocument.PICTURE_TYPE_WMF;  }  }  return res; } /**  * @param id  * @param width 宽  * @param height 高  * @param run 段落 */  public void createPicture(int id, String blipId, int width, int height,XWPFRun run) { final int EMU = 9525;  width *= EMU;  height *= EMU;   CTInline inline = run.getCTR().addNewDrawing().addNewInline();  String picXml = ""  + ""  + " "  + " "  + " " + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " "  + " " + "";   inline.addNewGraphic().addNewGraphicData();  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("图片" + id);  docPr.setDescr("测试");  }

输出docx文档

把返回的XWPFDocument写入到对应的流中。

FileOutputStream fopts = new FileOutputStream("E://andy.docx");doc.write(fopts);

转pdf文档

把XWPFDocument转成PDF：

FileOutputStream fopts = new FileOutputStream(new FIle("E://andy.pdf"));PdfOptions options = PdfOptions.create();options.fontProvider(new IFontProvider() { @Override public Font getFont(String s, String s1, float v, int i, Color color) { try { BaseFont bfChinese = BaseFont.createFont(rootPath + "wordtemplate/simsun.ttf
