JAVA读取WORD,EXCEL,POWERPOINT,PDF文件的方法

来自 panyi5202@javaresearch.org

OFFICE文档使用POI控件，PDF可以使用PDFBOX0.7.3控件，完全支持中文，用XPDF也行，不过感觉PDFBOX比较好，而且作者也在更新。

WORD:

import org.apache.lucene.document.Document;

import org.apache.lucene.document.Field;

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

import java.io.File;

import java.io.InputStream;

import java.io.FileInputStream;

import com.search.code.Index;

public Document getDocument(Index index, String url, String title, InputStream is) throws DocCenterException {

String bodyText = null;

try {

WordExtractor ex = new WordExtractor(is);//is是WORD文件的InputStream

bodyText = ex.getText();

if(!bodyText.equals("")){

index.AddIndex(url, title, bodyText);

}

}catch (DocCenterException e) {

throw new DocCenterException("无法从该Mocriosoft Word文档中提取内容", e);

}catch(Exception e){

e.printStackTrace();

}

}

return null;

}

Excel:

import org.apache.lucene.document.Document;

import org.apache.lucene.document.Field;

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

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.io.FileInputStream;

import com.search.code.Index;

public Document getDocument(Index index, String url, String title, InputStream is) throws DocCenterException {

StringBuffer content = new StringBuffer();

try{

HSSFWorkbook workbook = new HSSFWorkbook(is);//创建对Excel工作簿文件的引用

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

if (null != workbook.getSheetAt(numSheets)) {

HSSFSheet aSheet = workbook.getSheetAt(numSheets);//获得一个sheet

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

if (null != aSheet.getRow(rowNumOfSheet)) {

HSSFRow aRow = aSheet.getRow(rowNumOfSheet); //获得一个行

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

if (null != aRow.getCell(cellNumOfRow)) {

HSSFCell aCell = aRow.getCell(cellNumOfRow);//获得列值

content.append(aCell.getStringCellValue());

}

}

}

}

}

}

if(!content.equals("")){

index.AddIndex(url, title, content.toString());

}

}catch (DocCenterException e) {

throw new DocCenterException("无法从该Mocriosoft Word文档中提取内容", e);

}catch(Exception e) {

System.out.println("已运行xlRead() : " + e );

}

return null;

}

PowerPoint:

import java.io.InputStream;

import org.apache.lucene.document.Document;

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 Document getDocument(Index index, String url, String title, InputStream is)

throws DocCenterException {

StringBuffer content = new StringBuffer("");

try{

SlideShow ss = new SlideShow(new HSLFSlideShow(is));//is 为文件的InputStream，建立SlideShow

Slide[] slides = ss.getSlides();//获得每一张幻灯片

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

TextRun[] t = slides[i].getTextRuns();//为了取得幻灯片的文字内容，建立TextRun

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

content.append(t[j].getText());//这里会将文字内容加到content中去

}

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

}

index.AddIndex(url, title, content.toString());

}catch(Exception ex){

System.out.println(ex.toString());

}

return null;

}

PDF:
