POI處理Word、Excel、PowerPoint

第一：下載POI，在http://jakarta.apache.org/poi/中，下載poi-bin-3.5-beta4-20081128.zip，解壓後把jar包引入專案工程。

第二：處理Word（Word.java）

import org.apache.poi.hwpf.extractor.WordExtractor;

import java.io.File;

import java.io.InputStream;

 

public class Word {

    public static void main(String[] args) throws Exception {

       System.out.println(getContent("c:\\11.doc"));

    }

 

    public static String getContent(String s) throws Exception {

       return getContent(new java.io.FileInputStream(s));

    }

 

    public static String getContent(File f) throws Exception {

       return getContent(new java.io.FileInputStream(f));

    }

 

    public static String getContent(InputStream is) throws Exception {

       String bodyText = null;

       WordExtractor ex = new WordExtractor(is);

       bodyText = ex.getText();

       return bodyText;

    }

}

 
 

第三：處理Excel(Excel.java)

import org.apache.poi.hssf.usermodel.HSSFDateUtil;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;

import org.apache.poi.hssf.usermodel.HSSFSheet;

import org.apache.poi.hssf.usermodel.HSSFRow;

import org.apache.poi.hssf.usermodel.HSSFCell;

import java.io.File;

import java.io.InputStream;

import java.text.SimpleDateFormat;

import java.util.Date;

 

public class Excel {

    public static void main(String[] args) throws Exception {

       System.out.println(getContent("c:\\22.xls"));

    }

 

    public static String getContent(String s) throws Exception {

       return getContent(new java.io.FileInputStream(s));

    }

 

    public static String getContent(File f) throws Exception {

       return getContent(new java.io.FileInputStream(f));

    }

 

    public static String getContent(InputStream is) throws Exception {

       StringBuffer content = new StringBuffer();

       HSSFWorkbook workbook = new HSSFWorkbook(is);

       for (int numSheets = 0; numSheets < workbook.getNumberOfSheets(); numSheets++) {

           HSSFSheet aSheet = workbook.getSheetAt(numSheets);// 獲得一個sheet

           content.append("\n");

           if (null == aSheet) {

              continue;

           }

           for (int rowNum = 0; rowNum <= aSheet.getLastRowNum(); rowNum++) {

              content.append("\n");

              HSSFRow aRow = aSheet.getRow(rowNum);

              if (null == aRow) {

                  continue;

              }

              for (short cellNum = 0; cellNum <= aRow.getLastCellNum(); cellNum++) {

 

                  HSSFCell aCell = aRow.getCell(cellNum);

                  if (null == aCell) {

                     continue;

                  }

                  if (aCell.getCellType() == HSSFCell.CELL_TYPE_STRING) {

                     content.append(aCell.getRichStringCellValue()

                            .getString());

                  } else if (aCell.getCellType() == HSSFCell.CELL_TYPE_NUMERIC) {

                     boolean b = HSSFDateUtil.isCellDateFormatted(aCell);

                     if (b) {

                         Date date = aCell.getDateCellValue();

                         SimpleDateFormat df = new SimpleDateFormat(

                                "yyyy-MM-dd");

                         content.append(df.format(date));

                     }

                  }

              }

           }

       }

       return content.toString();

    }

}

 
 

第四：處理PowerPoint（PowerPoint.java）

import java.io.File;

import java.io.InputStream;

import org.apache.poi.hslf.HSLFSlideShow;

import org.apache.poi.hslf.model.TextRun;

import org.apache.poi.hslf.model.Slide;

import org.apache.poi.hslf.usermodel.SlideShow;

 

public class PowerPoint {

    public static void main(String[] args) throws Exception {

       System.out.println(getContent("c:\\33.ppt"));

    }

 

    public static String getContent(String s) throws Exception {

       return getContent(new java.io.FileInputStream(s));

    }

 

    public static String getContent(File f) throws Exception {

       return getContent(new java.io.FileInputStream(f));

    }

 

    public static String getContent(InputStream is) throws Exception {

       StringBuffer content = new StringBuffer("");

       SlideShow ss = new SlideShow(new HSLFSlideShow(is));

       Slide[] slides = ss.getSlides();

       for (int i = 0; i < slides.length; i++) {

           TextRun[] t = slides[i].getTextRuns();

           for (int j = 0; j < t.length; j++) {

              content.append(t[j].getText());

           }

           content.append(slides[i].getTitle());

       }

       return content.toString();

    }

}
