先要对pdf文件进行解析，然后显示出来

下面是解析pdf的代码：

package com.lingjoin.extractors;

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.IOException;

import java.io.StringReader;

import java.util.Date;

import org.apache.pdfbox.pdmodel.PDDocument;

import org.apache.pdfbox.pdmodel.PDDocumentInformation;

import org.apache.pdfbox.util.PDFTextStripper;

import com.lingjoin.paser.LingJoinFile;

/**

* PDF解析器

*

* @author Ansj

*

*/

public class PDFExtractor extends AbstractExtractor {

private String getContent(LingJoinFile f) {

// TODO Auto-generated method stub

PDDocument doc = null ;

try {

doc = PDDocument.load(f);

PDFTextStripper stripper = new PDFTextStripper();

/**

* 设置文件的信息

*/

this.setLingJoinFileInfo(f, doc

.getDocumentInformation());

return stripper.getText(doc);

} catch (FileNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} finally {

if (doc != null) {

try {

doc.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

return "";

}

private BufferedReader getContentReader(LingJoinFile f) {

return new BufferedReader(new StringReader(this.getContent(f)));

}

/**

*/

private void setLingJoinFileInfo(LingJoinFile f, PDDocumentInformation info) {

if (info.getAuthor() != null) {

f.setlAuthor(info.getAuthor());

}

}

public void paserFileToReader(LingJoinFile f) throws Exception {

f.setlContentReader(this.getContentReader(f)) ;

}

public void paserFileToString(LingJoinFile f) throws Exception {

// TODO Auto-generated method stub

f.setlContent(this.getContent(f)) ;

}

public PDFExtractor(Integer typeFlag) {

// TODO Auto-generated constructor stub

this.typeFlag = typeFlag ;

}

private Integer typeFlag = null ;

public Integer getTypeFlag() {

// TODO Auto-generated method stub

return typeFlag;

}

}

上面是用pdfbox实现的，只是部分不全的代码，同时还有用动态库so文件，读取图片。
