1.抽取word doc中的图片

package parse;
    
    import java.io.*;
    import java.util.*;
    
    
    import org.apache.poi.hwpf.HWPFDocument;
    import org.apache.poi.hwpf.model.PicturesTable;
    import org.apache.poi.hwpf.usermodel.CharacterRun;
    import org.apache.poi.hwpf.usermodel.Picture;
    import org.apache.poi.hwpf.usermodel.Range;
    
    public class ReadImgDoc { 
    
    public static void main(String[] args) throws Exception {   
      new ReadImgDoc().readPicture("E:\\上海项目测试\\文档\\模板.doc");
    }
    
      private void readPicture(String path)throws Exception{
         FileInputStream in=new FileInputStream(new File(path)); 
         HWPFDocument doc=new HWPFDocument(in); 
         int length=doc.characterLength();
         PicturesTable pTable=doc.getPicturesTable();
        // int TitleLength=doc.getSummaryInformation().getTitle().length();
    
         //  System.out.println(TitleLength);
          // System.out.println(length);
           for (int i=0;i<length;i++){ 
             Range range=new Range(i, i+1,doc);
    
             CharacterRun cr=range.getCharacterRun(0);
             if(pTable.hasPicture(cr)){
                Picture pic=pTable.extractPicture(cr, false);
              String afileName=pic.suggestFullFileName();
              OutputStream out=new FileOutputStream(new File("E:\\上海项目测试\\docImage\\"+UUID.randomUUID()+afileName));
              pic.writeImageContent(out);
    
            }
           }
    
      }
    
    }

2.抽取 word docx文件中的图片

package parse;
    
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.util.List;
    
    import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
    import org.apache.poi.xwpf.usermodel.XWPFDocument;
    import org.apache.poi.xwpf.usermodel.XWPFPictureData;
    
    public class GetPicsDocx {
      public static void main(String[] args) {
        String path ="E:\\上海项目测试\\文档\\35.docx";
        File file = new File(path);
        try {
          FileInputStream fis = new FileInputStream(file);
          XWPFDocument document = new XWPFDocument(fis);
          XWPFWordExtractor xwpfWordExtractor = new XWPFWordExtractor(document);
          String text = xwpfWordExtractor.getText();
          System.out.println(text);
          List<XWPFPictureData> picList = document.getAllPictures();
          for (XWPFPictureData pic : picList) {
            System.out.println(pic.getPictureType() + file.separator + pic.suggestFileExtension()
                +file.separator+pic.getFileName());
            byte[] bytev = pic.getData();
            FileOutputStream fos = new FileOutputStream("E:\\上海项目测试\\docxImage\\"+pic.getFileName()); 
            fos.write(bytev);
          }
          fis.close();
        } catch (IOException e) {
          e.printStackTrace();
        }
      }
    }
