在word文档中插入图片
这是我第一次使用Apache POI，我已经在本网站上提出了我要问的问题，但没有给出明确的答案，所以我别无选择，只能接受你的帮助。
我正在尝试编写一个java程序，它从一个文件夹中获取图像并将该图像插入到word文档中。 我在这个程序中使用Apache POI。 我在这里发布我的代码。
import java.io.*; import java.util.*; import org.apache.poi.util.IOUtils; import org.apache.poi.xwpf.usermodel.*; public class ImagesDoc { public static void main(String[] args) throws IOException { XWPFDocument docx = new XWPFDocument(); XWPFParagraph par = docx.createParagraph(); XWPFRun run = par.createRun(); run.setText("Hello, World. This is my first java generated docx-file. Have fun."); run.setFontSize(13); InputStream pic = new FileInputStream("C:\\Users\\amitabh\\Pictures\\pics\\pool.jpg"); byte [] picbytes = IOUtils.toByteArray(pic); docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); FileOutputStream out = new FileOutputStream("C:\\Users\\amitabh\\Pictures\\pics\\simple1.docx"); docx.write(out); out.close(); pic.close(); } } 我能够创建word文档文件，我也可以插入文本，但docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); line给出了错误“add cast to docx”。 我为这个程序添加了所有可能的jar子。 对于这个错误，我在网上搜索，发现很多人都有类似的问题。 XWPFDocument引用的“addPicture”无法正常工作。 请帮我解决这个问题。
首先，我想指出apache poi提供的示例 – Link ，即正确的方法
doc.createParagraph().createRun().addPicture(new FileInputStream(imgFile), format, imgFile, Units.toEMU(200), Units.toEMU(200));
但是，在执行上述语句后仍然存在导致.docx文件无法读取的现有错误。 它可能很快得到解决，在这种情况下，上述声明将完成工作。 与此同时，还有一种解决方法。
首先，生成没有任何图片的docx文件。 然后将此类CustomXWPFDocument添加到您的包中。
import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.xmlbeans.XmlException; import org.apache.xmlbeans.XmlToken; import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps; import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D; import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline; import java.io.IOException; import java.io.InputStream; public class CustomXWPFDocument extends XWPFDocument { public CustomXWPFDocument(InputStream in) throws IOException { super(in); } public void createPicture(String blipId,int id, int width, int height) { final int EMU = 9525; width *= EMU; height *= EMU; //String blipId = getAllPictures().get(id).getPackageRelationship().getId(); CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline(); String picXml = "" + "" + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " " + " "; //CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData(); XmlToken xmlToken = null; try { xmlToken = XmlToken.Factory.parse(picXml); } catch(XmlException xe) { xe.printStackTrace(); } inline.set(xmlToken); //graphicData.set(xmlToken); inline.setDistT(0); inline.setDistB(0); inline.setDistL(0); inline.setDistR(0); CTPositiveSize2D extent = inline.addNewExtent(); extent.setCx(width); extent.setCy(height); CTNonVisualDrawingProps docPr = inline.addNewDocPr(); docPr.setId(id); docPr.setName("Picture " + id); docPr.setDescr("Generated"); } }
然后，通过添加如下图片来创建更新的文档： –
CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\doc1.docx"))); FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\Avarice\\Desktop\\doc2.docx")); String id = document.addPictureData(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\thumbnail.jpg")), Document.PICTURE_TYPE_JPEG); document.createPicture(id,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 64, 64); document.write(fos); fos.flush(); fos.close();
您还应该在构建路径中包含以下jar： –
POI-OOXML-模式
的xmlbeans
DOM4J
I have used poi 3.10 to generate word doc and to insert a picture. you need 2 classes.. here is the example import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.text.DateFormat; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.List; import org.apache.poi.openxml4j.exceptions.InvalidFormatException; import org.apache.poi.util.Units; import org.apache.poi.xwpf.model.XWPFHeaderFooterPolicy; import org.apache.poi.xwpf.usermodel.Document; import org.apache.poi.xwpf.usermodel.ParagraphAlignment; import org.apache.poi.xwpf.usermodel.UnderlinePatterns; import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.poi.xwpf.usermodel.XWPFHeader; import org.apache.poi.xwpf.usermodel.XWPFParagraph; import org.apache.poi.xwpf.usermodel.XWPFRun; import org.apache.xmlbeans.XmlException; import org.openxmlformats.schemas.wordprocessingml.x2006.main.*; public class ImageAttachmentInDocument { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { DateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy"); Calendar cal = Calendar.getInstance(); String date = dateFormat.format(cal.getTime()); // Create a document file CustomXWPFDocument document = new CustomXWPFDocument(); // Adding a file try { // Working addPicture Code below...
