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();
     }
   }
 }
