这是我第一次在Apache POI上工作,而我将要问的问题已经在这个网站上被问到,但是没有给出明确的答案,所以我别无选择,只能用你的帮助.
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.我正在使用Apache POI进行此程序.在这里我发贴我的代码
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(); } }
我可以创建word文档文件,我也可以插入文本docx.addPicture(picbytes,Document.PICTURE_TYPE_JPEG);线路给我的错误是“添加到docx”.我已经添加了这个程序的所有可能的罐子.对于这个错误,我搜索了整个网络,发现很多人都有类似的问题. XWPFDocument引用的“addPicture”不起作用.请帮我解决这个问题.
解决方法
首先,我想指出apache poi-
Link提供的例子,即正确的做法
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,仍然存在一个现有的错误,导致.docx文件不可读.这可能会很快解决,在这种情况下,上述声明将会进行.与此同时,还有一个解决方案.
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 = "" + "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" + " <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" + " <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" + " <pic:nvPicPr>" + " <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" + " <pic:cNvPicPr/>" + " </pic:nvPicPr>" + " <pic:blipFill>" + " <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" + " <a:stretch>" + " <a:fillRect/>" + " </a:stretch>" + " </pic:blipFill>" + " <pic:spPr>" + " <a:xfrm>" + " <a:off x=\"0\" y=\"0\"/>" + " <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" + " </a:xfrm>" + " <a:prstGeom prst=\"rect\">" + " <a:avLst/>" + " </a:prstGeom>" + " </pic:spPr>" + " </pic:pic>" + " </a:graphicData>" + "</a:graphic>"; //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"); } }
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具有以下jar:
POI-OOXML-模式
