这几天想通过一个现有word文件作为模板，然后根据标签写入对应数据，折腾了好几天了。

text解决了，表格解决了，结果才发现图片用XWPFDocument压根无法实现addPicture，POI自身有bug，图片是加入到word文件里面了，可是显示不了。。。

于是乎，又折腾了2天，终于整蛊了怎么让图片在里面显示出来，其他的还在进一步解决中。

贴个小代码给大家用，凑合着用，还有很多需要修改的：

		// CTGraphicalObjectData graphicData =

		XmlToken xmlToken = null;
		try {

		inline.set(xmlToken);
		// graphicData.set(xmlToken);

		inline.setDistT(0);

		CTNonVisualDrawingProps docPr = inline.addNewDocPr();
		docPr.setId(id);

	}
}

 调用方法大概是这样的：

   OPCPackage pack = POIXMLDocument.openPackage(fileName);
   CustomXWPFDocument doc = new CustomXWPFDocument(pack);
   int ind = doc.addPicture(new FileInputStream("d:\\甩葱玩具.jpg"), XWPFDocument.PICTURE_TYPE_JPEG);
   doc.createPicture(ind, 259, 58);
