将word（docx）文档与Docx4J合并：如何复制图像？

Question

下面是一个简单的例子：

first.docx=简单文本
second.docx=简单文本+图像

    File first = new File("first.docx");
    File second = new File("second.docx");

    WordprocessingMLPackage f = WordprocessingMLPackage.load(first);
    WordprocessingMLPackage s = WordprocessingMLPackage.load(second);

    List body = s.getMainDocumentPart().getJAXBNodesViaXPath("//w:body", false);
    for(Object b : body){
        List filhos = ((org.docx4j.wml.Body)b).getContent();
        for(Object k : filhos)
            f.getMainDocumentPart().addObject(k);
    }

    List blips = s.getMainDocumentPart().getJAXBNodesViaXPath("//a:blip", false);
    for(Object el : blips){
        try {
            CTBlip blip = (CTBlip) el;

            RelationshipsPart parts = s.getMainDocumentPart().getRelationshipsPart();
            Relationship rel = parts.getRelationshipByID(blip.getEmbed());

            RelationshipsPart docRels = f.getMainDocumentPart().getRelationshipsPart();

            rel.setId(null);
            docRels.addRelationship(rel);
            blip.setEmbed(rel.getId());

            f.getMainDocumentPart().addTargetPart(s.getParts().getParts().get(new PartName("/word/"+rel.getTarget())));

        } catch (Exception ex){}
    }

    File saved = new File("saved.docx");
    f.save(saved);

    Desktop.getDesktop().open(saved);

问题是我什么时候存钱。出现以下错误：

Answer 1

在将s中的blips添加到f之前，先操作它们。换句话说，交换for循环的顺序。

然后在你的回旋操作中，你需要做的是：

• 获取感兴趣的部分
• rel rel=f.getmainDocumentPart().addTargetPart
• 从rel.getid更新blip中的relId
