aspose.word 20 java 替换占位符为文字或图片

以前写过用asposeword 替换文字和图片，但是后来遇到问题，有些word替换替换图片后会导致打开时弹出错误：此文件中检测到错误，单word可以通过进行一下修复来打开文件。

考虑可能是版本有bug，于是从官网下了最新的20.7版本。

下载：aspose word for java 20.7

新版替换字符为图片的方法有些不一样

使用方法：

package xf.test;import com.aspose.words.*;import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;public class TestAspose {public static void main(String[] args) {try {//doc 和docx 都是可以的Map<String,String>pmap = new HashMap<String,String>();pmap.put("[编写签名区域]","$pic:D:/javatest/sign2.png");pmap.put("$编号$","BH12345");//replace("D:/javatest/test删除图片.doc","D:/javatest/aspose测试删除图片.doc",pmap);
//            replace("D:/javatest/田清单A8.docx","D:/javatest/aspose测试删除图片.docx",pmap);replace("D:/javatest/aspose测试删除图片.docx","D:/javatest/aspose测试删除图片2.docx",pmap);}catch (Exception e){e.printStackTrace();}}public static boolean replace(String path, String outPath, Map<String,String> paramMap){if(path == null || path.isEmpty()) return false;if(outPath == null || outPath.isEmpty()) return false;if(paramMap == null || paramMap.isEmpty()) return false;try {Document doc = new Document(path);Iterator<String> paramKey = paramMap.keySet().iterator();while(paramKey.hasNext()){String key = paramKey.next();String v = paramMap.get(key);if(v.startsWith("$pic:")){v = v.substring(5);//如果key已经被替换成图片了，那就要将图片替换成新的图片，相当于重新插入图片NodeCollection shapeCollection = doc.getChildNodes(NodeType.SHAPE, true);Iterator<Shape>  shapeIterate =  shapeCollection.iterator();java.util.List<Shape> shaplist = new ArrayList<Shape>();while(shapeIterate.hasNext()){Shape shape = shapeIterate.next();if(key.equals(shape.getName())){shaplist.add(shape);}}DocumentBuilder builder = new DocumentBuilder(doc);for(int i=0;i<shaplist.size();i++){Shape shape = shaplist.get(i);//将光标移动到指定节点builder.moveTo(shape);Shape img = builder.insertImage(v);img.setName(key);System.out.println("replace" +key);shape.remove();}//替换文字为图片doc.getRange().replace(key, "", new FindReplaceOptions(new ReplaceAndInsertImage(v,key)));}else{doc.getRange().replace(key,v);}}doc.save(outPath);}catch (Exception e){e.printStackTrace();return false;}return true;}
}class ReplaceAndInsertImage implements IReplacingCallback {private String url;private String name;public ReplaceAndInsertImage(String url,String name){this.url = url;this.name = name;}@Overridepublic int replacing(ReplacingArgs e) throws Exception {//获取当前节点Node currentNode = e.getMatchNode();//节点拆分处理当前匹配字段splitRun(currentNode,e.getMatchOffset());//获取当前文档Document document =  (Document) currentNode.getDocument();DocumentBuilder builder = new DocumentBuilder(document);//将光标移动到指定节点builder.moveTo(currentNode);//插入图片Shape img = builder.insertImage(url);img.setName(name);return ReplaceAction.SKIP;}private void splitRun(Node currentNode ,int position){String text =  currentNode.getText();Node newNode = currentNode.deepClone(true);if(text.length() >= position+this.name.length()){((Run)currentNode).setText (text.substring(position+this.name.length()));}else{int morlength = position+this.name.length() - text.length();((Run)currentNode).setText ("");Node tmpnode = currentNode;for(int i=0;i<this.name.length();i++){System.out.println(i);tmpnode = tmpnode.getNextSibling();String tmptext= tmpnode.getText();System.out.println(tmptext);System.out.println(morlength);System.out.println("--------"+(tmptext.length() >= morlength));if(tmptext.length() >= morlength){((Run)tmpnode).setText(tmptext.substring(morlength));break;}else{morlength = morlength - tmptext.length();((Run)tmpnode).setText("");}}}if(position>0){((Run)newNode).setText(text.substring(0, position));currentNode.getParentNode().insertBefore(newNode, currentNode);}}
}

20200813更新：原方法处理doc时存在bug，替换占位符为图片后，图片不是在占位符所在的位置，而是在占位符所在的node的起始位置，增加splitRun方法分割node节点。
