关于插入新的引用文件的思考

在POIXMLDocumentPart类中，存在可以获取文档引用信息的方法，并且通过api建立引用文件好像也是可以实现的，而有关这个功能的的实现就需要依靠下面这个方法：

  1. private void addRelation(PackageRelationship pr, POIXMLDocumentPart part) {
  2.   this.relations.put(pr.getId(), new POIXMLDocumentPart.RelationPart(pr, part));
  3.   part.incrementRelationCounter();
  4. }

我们先查看一下输入文档原引用信息：

  1. POIXMLDocumentPart poixmlDocumentPart = xwpfDocument.getPart();
  2. List<POIXMLDocumentPart.RelationPart> relationParts = poixmlDocumentPart.getRelationParts();
  3. for(POIXMLDocumentPart.RelationPart relationPart : relationParts){
  4.     System.out.println("引用id："+relationPart.getRelationship().getId());
  5.     System.out.println("引用类型："+relationPart.getRelationship().getRelationshipType());
  6.     System.out.println("引用文件指向地址："+relationPart.getRelationship().getTargetURI().getPath());
  7.     System.out.println("被引用地址："+relationPart.getRelationship().getSourceURI().getPath());
  8.     System.out.println(relationPart.getDocumentPart());
  9.     System.out.println();
  10. }

打印，控制台显示结果摘录如下：

因此，如果我们要构建一个页眉页脚引用文件，那么首先得补齐这些信息

另外在查看PackageRelationship类的源码时发现，引用文件的路径应该使用相对路径，使用java.net.URI类进行包装，例如此类的静态代码块：

  1. static {
  2.     try {
  3.         containerRelationshipPart = new URI("/_rels/.rels");
  4.     } catch (URISyntaxException var1) {
  5.     }

其类PackageRelationship属性如下：

  1. public final class PackageRelationship {
  2.     private static URI containerRelationshipPart;
  3.     public static final String ID_ATTRIBUTE_NAME = "Id";
  4.     public static final String RELATIONSHIPS_TAG_NAME = "Relationships";
  5.     public static final String RELATIONSHIP_TAG_NAME = "Relationship";
  6.     public static final String TARGET_ATTRIBUTE_NAME = "Target";
  7.     public static final String TARGET_MODE_ATTRIBUTE_NAME = "TargetMode";
  8.     public static final String TYPE_ATTRIBUTE_NAME = "Type";
  9.     private String id;
  10.     private OPCPackage container;
  11.     private String relationshipType;
  12.     private PackagePart source;
  13.     private TargetMode targetMode;
  14.     private URI targetUri;

构造方法如下：

  1. public PackageRelationship(OPCPackage pkg, PackagePart sourcePart, URI targetUri, TargetMode targetMode, String relationshipType, String id) {
  2.     if (pkg == null) {
  3.         throw new IllegalArgumentException("pkg");
  4.     } else if (targetUri == null) {
  5.         throw new IllegalArgumentException("targetUri");
  6.     } else if (relationshipType == null) {
  7.         throw new IllegalArgumentException("relationshipType");
  8.     } else if (id == null) {
  9.         throw new IllegalArgumentException("id");
  10.     } else {
  11.         this.container = pkg;
  12.         this.source = sourcePart;
  13.         this.targetUri = targetUri;
  14.         this.targetMode = targetMode;
  15.         this.relationshipType = relationshipType;
  16.         this.id = id;
  17.     }
  18. }

在获取当前这个引用对象的元数据包时，可以结合属性

  1. private OPCPackage container;

调用方法

  1. public OPCPackage getPackage() {
  2.     return this.container;
  3. }

另外一个未知属性sourcePart在当前类中并没有被使用上，因此暂时不知道是什么

在这里遭遇一个令人窒息的逻辑闭环：
在rel.rel文件中放入新的引用信息 -> 需要提供引用对象 -> 创建引用对象需要该引用文件在此文件中的相对地址->但是要插入的文件根本就还没有放进去？？？-> 不能在rel文件中插入新的引用信息

所以，在将引用文件插入到rel.rel文件之前，应该先把这个引用文件添加进文档压缩包里面去

清除整个引用文件

  1. xwpfDocument.getPart().getPackagePart().clearRelationships();

即删除了document.xml.rels文件，但是被引用的诸如页眉页脚信息依旧存在
偶然发现poi底层使用了大量的集合数据结构

如何构建一个页眉页脚文件

再一次偶然中，我发现了一种新的类型：

  1. HdrDocument hdrDocument = null;
  2. try {
  3.     hdrDocument = HdrDocument.Factory.parse(new File("E:\\header1.xml"));
  4. } catch (XmlException e) {
  5.     e.printStackTrace();
  6. } catch (IOException e) {
  7.     e.printStackTrace();
  8. }

HdrDocument类和页眉页脚文件：

  1. <?xml version="1.0" encoding="utf-8" standalone="yes"?>
  2. <w:hdr xmlns:v="urn:schemas-microsoft-com:vml" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:ve="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml" xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing" xmlns:wps="http://schemas.microsoft.com/office/word/2010/wordprocessingShape" xmlns:wpg="http://schemas.microsoft.com/office/word/2010/wordprocessingGroup" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
  3.     <w:p>
  4.         <w:pPr>
  5.             <w:jc w:val="right" />
  6.         </w:pPr>
  7.         <w:r>
  8.             <w:rPr>
  9.                 <w:b />
  10.                 <w:color w:val="0000FF" />
  11.                 <w:sz w:val="30" />
  12.             </w:rPr>
  13.             <w:t xml:space="preserve">偶数页页眉</w:t>
  14.         </w:r>
  15.     </w:p>
  16. </w:hdr>

第一个标签的前缀是吻合的，那么可以推断出，这个就是我们想找的页眉页脚文件的对象。

但是接下来一个问题是：找到了可以存放的对象，但是怎么把这个对象加载进目前的文档中呢

如何利用已知uri路径从引用文件中提取到对应的文件

此处从PackageRelationship先入手，其中有一个静态区块：

  1. static {
  2.     try {
  3.         containerRelationshipPart = new URI("/_rels/.rels");
  4.     } catch (URISyntaxException var1) {
  5.     }
  7. }

在poi中有一个类：XWPFRelation

  1. public final class XWPFRelation extends POIXMLRelation {
  2.     private static final Map<String, XWPFRelation> _table = new HashMap();
  3.     public static final XWPFRelation DOCUMENT = new XWPFRelation("application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument", "/word/document.xml");
  4.     public static final XWPFRelation TEMPLATE = new XWPFRelation("application/vnd.openxmlformats-officedocument.wordprocessingml.template.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument", "/word/document.xml");
