poi|POI对word模板内容替换及图片插入 poi|word|java

POI对word模板内容替换及图片插入项目中需要将一些数据及图片填入word模板。看了一些前辈的博客，借鉴了一些东西，在此总结一下。如有不对的地方请指正，侵权请联系删除。本人使用的poi版本为3.9。
一、pom.xml

org.apache.poi poi 3.9 org.apache.poi poi-scratchpad 3.9 org.apache.poi poi-ooxml 3.9

二、WordUtil工具类

import org.apache.poi.openxml4j.exceptions.InvalidFormatException; import org.apache.poi.xwpf.usermodel.*; import org.apache.xmlbeans.XmlException; import org.apache.xmlbeans.XmlToken; import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps; import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D; import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.util.Iterator; import java.util.List; import java.util.Map; import java.util.Map.Entry; public class WordUtil { /** *适用于word 2007 * @param param需要替换的参数 * @param template 模板 */ public static XWPFDocument generateWord(Map, Object> param, String template) { XWPFDocument doc = null; try { OPCPackage pack = POIXMLDocument.openPackage(template); //通过路径获取word模板 doc = new CustomXWPFDocument(pack); //通过InputStream 获取模板，此方法适用于jar包部署 //doc = new CustomXWPFDocument(template); 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 * @throws FileNotFoundException * @throws InvalidFormatException */ public static void processParagraphs(List paragraphList, Map, Object> param, XWPFDocument doc) throws InvalidFormatException, FileNotFoundException { 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, Object> entry : param.entrySet()) { String key = "${" + entry.getKey() + "}"; if (text.indexOf(key) != -1) { isSetText = true; Object value = https://www.it610.com/article/entry.getValue(); if (value instanceof String) {//文本替换 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()); //获取图片流，因本人项目中适用流 //InputStream is = (InputStream) pic.get("content"); String byteArray = (String) pic.get("content"); CTInline inline = run.getCTR().addNewDrawing().addNewInline(); insertPicture(doc, byteArray, inline, width, height,picType); } } } if (isSetText) { run.setText(text, 0); } } } } } }/** * 获取图片对应类型代码 * @param picType * @return int */ private static 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; }/** * insert Picture * @param document * @param filePath * @param inline * @param width * @param height * @throws InvalidFormatException * @throws FileNotFoundException */ private static void insertPicture(XWPFDocument document, String filePath, CTInline inline, int width, int height,int imgType) throws InvalidFormatException, FileNotFoundException { //通过流获取图片，因本人项目中，是通过流获取 //document.addPictureData(imgFile,imgType); document.addPictureData(new FileInputStream(filePath),imgType); int id = document.getAllPictures().size() - 1; final int EMU = 9525; width *= EMU; height *= EMU; String blipId = document.getAllPictures().get(id).getPackageRelationship().getId(); 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); }/** * get the xml of the picture * * @param blipId * @param width * @param height * @return */ private static String getPicXml(String blipId, int width, int height) { String picXml = "" + "" + "" + "" + "" + " + 0 + "\" name=\"Generated\"/>" + "" + "" + "" + "+ blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" + "" + "" + "" + "" + "" + "" + "" + "+ width + "\" cy=\"" + height + "\"/>" + "" + "" + "" + "" + "" + "" + "" + ""; return picXml; } }

三、CustomXWPFDocument类

import org.apache.poi.openxml4j.opc.OPCPackage; import org.apache.poi.xwpf.usermodel.XWPFDocument; import java.io.IOException; import java.io.InputStream; public class CustomXWPFDocument extends XWPFDocument {public CustomXWPFDocument(InputStream in) throws IOException { super(in); }public CustomXWPFDocument() { super(); }public CustomXWPFDocument(OPCPackage pkg) throws IOException { super(pkg); } }

五、测试类

public static void main(String[] args) throws Exception { Map,Object> param = new HashMap, Object>(); map.put("proName","合规性分析测试"); map.put("proType","总体规划"); map.put("nonConstrArea","25438834.17"); map.put("constrArea","0.00"); Map,Object> header = new HashMap, Object>(); header.put("width", 556); header.put("height", 230); header.put("type", "png"); header.put("content", "F:\\picture\\test.png"); //图片路径 param.put("{picture}",header); XWPFDocument doc = WordUtil.generateWord(param, "F:\\wordTemplate.docx"); FileOutputStream fopts = new FileOutputStream("F:\\test.docx"); doc.write(fopts); fopts.close(); }
