当我节省处理一些文本使用POI的XPath后的docx文件，我则ByteArrayOutputStream传递到一个新的ByteArrayInputStream的和饲料它与docx4j无法读取POI保存的文件，谁有错？
wordMLPackage = WordprocessingMLPackage.load(
bis
);
到dox4j随着4分之3的我的模板，这将引发一个例外：
org.docx4j.openpackaging.exceptions.InvalidFormatException: Unexpected package (docx4j supports docx/docxm and pptx only
at org.docx4j.openpackaging.contenttype.ContentTypeManager.createPackage(ContentTypeManager.java:834)
的代码看起来是这样的：
/* Return a package of the appropriate type. Used when loading an existing
* Package, with an already populated [Content_Types].xml. When
* creating a new Package, start with the new WordprocessingMLPackage constructor. */
public OpcPackage createPackage() throws InvalidFormatException {
/*
* How do we know what type of Package this is?
*
* In principle, either:
*
* 1. We were told its file extension or mime type in the
* constructor/method parameters, or
*
* 2. Because [Content_Types].xml contains an override for PartName
* /document.xml of content type
* application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml
*
* The latter approach is more reliable, so ..
*
*/
OpcPackage p;
if (getPartNameOverridenByContentType(ContentTypes.WORDPROCESSINGML_DOCUMENT) != null
|| getPartNameOverridenByContentType(ContentTypes.WORDPROCESSINGML_DOCUMENT_MACROENABLED) != null
|| getPartNameOverridenByContentType(ContentTypes.WORDPROCESSINGML_TEMPLATE) != null
|| getPartNameOverridenByContentType(ContentTypes.WORDPROCESSINGML_TEMPLATE_MACROENABLED) != null) {
log.info("Detected WordProcessingML package ");
p = new WordprocessingMLPackage(this);
return p;
} else if (getPartNameOverridenByContentType(ContentTypes.PRESENTATIONML_MAIN) != null
|| getPartNameOverridenByContentType(ContentTypes.PRESENTATIONML_TEMPLATE) != null
|| getPartNameOverridenByContentType(ContentTypes.PRESENTATIONML_SLIDESHOW) != null) {
log.info("Detected PresentationMLPackage package ");
p = new PresentationMLPackage(this);
return p;
} else if (getPartNameOverridenByContentType(ContentTypes.SPREADSHEETML_WORKBOOK) != null
|| getPartNameOverridenByContentType(ContentTypes.SPREADSHEETML_WORKBOOK_MACROENABLED) != null
|| getPartNameOverridenByContentType(ContentTypes.SPREADSHEETML_TEMPLATE) != null
|| getPartNameOverridenByContentType(ContentTypes.SPREADSHEETML_TEMPLATE_MACROENABLED) != null) {
// "xlam", "xlsb" ?
log.info("Detected SpreadhseetMLPackage package ");
p = new SpreadsheetMLPackage(this);
return p;
} else if (getPartNameOverridenByContentType(ContentTypes.DRAWINGML_DIAGRAM_LAYOUT) != null) {
log.info("Detected Glox file ");
p = new GloxPackage(this);

}
这似乎是无法匹配一些特定的内容类型覆盖。在我的出发DOCX模板有一个[CONTENT_TYPES] .xml文件其中有：
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
<Override PartName="/_rels/.rels" ContentType="application/vnd.openxmlformats-package.relationships+xml" />
<Override PartName="/word/fontTable.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.fontTable+xml" />
<Override PartName="/word/_rels/document.xml.rels" ContentType="application/vnd.openxmlformats-package.relationships+xml" />
<Override PartName="/word/media/image1.wmf" ContentType="image/x-wmf" />
<Override PartName="/word/comments.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.comments+xml" />
<Override PartName="/word/numbering.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.numbering+xml" />
<Override PartName="/word/footer1.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.footer+xml" />
<Override PartName="/word/document.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml" />
<Override PartName="/word/styles.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.styles+xml" />
<Override PartName="/docProps/app.xml" ContentType="application/vnd.openxmlformats-officedocument.extended-properties+xml" />
<Override PartName="/docProps/core.xml" ContentType="application/vnd.openxmlformats-package.core-properties+xml" />
</Types>
与POI处理后的[CONTENT_TYPES] .XML看起来是这样的：
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
<Default Extension="xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml"/>
<Override PartName="/_rels/.rels" ContentType="application/vnd.openxmlformats-package.relationships+xml"/>
<Override PartName="/docProps/app.xml" ContentType="application/vnd.openxmlformats-officedocument.extended-properties+xml"/>
<Override PartName="/docProps/core.xml" ContentType="application/vnd.openxmlformats-package.core-properties+xml"/>
<Override PartName="/word/_rels/document.xml.rels" ContentType="application/vnd.openxmlformats-package.relationships+xml"/>
<Override PartName="/word/comments.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.comments+xml"/>
<Override PartName="/word/fontTable.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.fontTable+xml"/>
<Override PartName="/word/footer1.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.footer+xml"/>
<Override PartName="/word/media/image1.wmf" ContentType="image/x-wmf"/>
<Override PartName="/word/numbering.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.numbering+xml"/>
<Override PartName="/word/styles.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.styles+xml"/>
</Types>
注意，占优PartName =“/ word/document.xml”缺失！
这是无字可接受的文件内容类型的文件/ document.xml中重写？它在LibreOffice中打开，没有投诉。是docx4j依靠其可能不存在的内容类型，或POI不正确书写的内容类型我的一些文件（3出4）覆盖的标签。
我认为这是一个错误docx4j - POI被设置与docx4j看起来是忽略了正确类型的默认。 – Gagravarr 2013-02-21 16:51:22
我同意，我已经在github项目上打开了第46期的一些代码想法来解决它。我仍然想知道规范说的Override标签。 – chugadie 2013-02-21 18:13:57
