Apache的POI項目可以用來處理MS Office文檔，codeplex上還有一個它的.net版本。POI項目可創建和維護操作各種基于OOXML和OLE2文件格式的Java API。大多數MS Office都是OLE2格式的。POI通HSMF子項目來支持Outlook，通過HDGF子項目來支持Visio，通過HPBF子項目來支持Publisher。

使用POI抽取Word簡單示例：

要引入poi-3.7.jat和poi-scratchpad-3.7.ajr這兩個包。

package msoffice;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import org.apache.poi.hwpf.HWPFDocument;

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

import org.apache.poi.hwpf.usermodel.CharacterRun;

import org.apache.poi.hwpf.usermodel.Paragraph;

import org.apache.poi.hwpf.usermodel.Range;

import org.apache.poi.hwpf.usermodel.Section;

public class Word {

// 直接抽取全部內容

public static String readDoc1(InputStream is) throws IOException {

WordExtractor extractor = new WordExtractor(is);

return extractor.getText();

}

//分章節Section、段落Paragraph、字符串CharacterRun抽取

public static void readDoc2(InputStream is) throws IOException {

HWPFDocument doc=new HWPFDocument(is);

Range r=doc.getRange();

for(int x=0;x

Section s=r.getSection(x);

for(int y=0;y

Paragraph p=s.getParagraph(y);

for(int z=0;z

CharacterRun run=p.getCharacterRun(z);

String text=run.text();

System.out.print(text);

}

}

}

}

public static void main(String[] args) {

File file = new File("/home/orisun/1.doc");

try {

FileInputStream fin = new FileInputStream(file);

String cont = readDoc1(fin);

System.out.println(cont);

fin.close();

fin = new FileInputStream(file);

readDoc2(fin);

fin.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

POI抽取PPT示例：

package msoffice;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import org.apache.poi.hslf.HSLFSlideShow;

import org.apache.poi.hslf.extractor.PowerPointExtractor;

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

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

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

public class PPT {

//直接抽取幻燈片的全部內容

public static String readDoc1(InputStream is) throws IOException{

PowerPointExtractor extractor=new PowerPointExtractor(is);

return extractor.getText();

}

//一張幻燈片一張幻燈片地讀取

public static void readDoc2(InputStream is) throws IOException{

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

Slide[] slides=ss.getSlides();

for(int i=0;i

//讀取一張幻燈片的標題

String title=slides[i].getTitle();

System.out.println("標題:"+title);

//讀取一張幻燈片的內容(包括標題)

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

for(int j=0;j

System.out.println(runs[j].getText());

}

}

}

public static void main(String[] args){

File file = new File("/home/orisun/2.ppt");

try{

FileInputStream fin=new FileInputStream(file);

String cont=readDoc1(fin);

System.out.println(cont);

fin.close();

fin=new FileInputStream(file);

readDoc2(fin);

fin.close();

}catch(IOException e){

e.printStackTrace();

}

}

}

Excel文件由多個Workbook組成，一個Workbook由多個Sheet組成。

POI抽取Excel簡單示例：

package msoffice;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import java.util.Iterator;

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

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

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

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

import org.apache.poi.hssf.extractor.ExcelExtractor;

import org.apache.poi.poifs.filesystem.POIFSFileSystem;

import org.apache.poi.ss.usermodel.Row;

public class Excel {

//直接讀取Excel的全部內容

public static String readDoc1(InputStream is)throws IOException{

HSSFWorkbook wb=new HSSFWorkbook(new POIFSFileSystem(is));

ExcelExtractor extractor=new ExcelExtractor(wb);

extractor.setFormulasNotResults(false);

extractor.setIncludeSheetNames(true);

return extractor.getText();

}

//讀取時細化到Sheet、行甚至單元格

public static double getAvg(InputStream is)throws IOException{

HSSFWorkbook wb=new HSSFWorkbook(new POIFSFileSystem(is));

//獲取第一張sheet

HSSFSheet sheet=wb.getSheetAt(0);

double molecule=0.0;

double denominator=0.0;

//按行遍歷sheet

Iterator riter=sheet.rowIterator();

while(riter.hasNext()){

HSSFRow row=(HSSFRow)riter.next();

HSSFCell cell1=row.getCell(4);

HSSFCell cell2=row.getCell(4);

if(cell1.getCellType()!=HSSFCell.CELL_TYPE_NUMERIC){

System.err.println("數字類型錯誤！");

System.exit(-2);

}

if(cell2.getCellType()!=HSSFCell.CELL_TYPE_NUMERIC){

System.err.println("數字類型錯誤！");

System.exit(-2);

}

denominator+=Double.parseDouble(cell2.toString().trim());

molecule+=Double.parseDouble(cell2.toString().trim())*Float.parseFloat(cell1.toString().trim());

}

return molecule/denominator;

}

public static void main(String[] args){

File file = new File("/home/orisun/3.xls");

try{

FileInputStream fin=new FileInputStream(file);

String cont=readDoc1(fin);

System.out.println(cont);

fin.close();

fin=new FileInputStream(file);

System.out.println("加權平均分"+getAvg(fin));

fin.close();

}catch(IOException e){

e.printStackTrace();

}

}

}
