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。

依赖的包

org.apache.poi poi 3.15org.apache.poi poi-ooxml 3.15

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"); }
