PDF处理两例

1，PDF生成图片
java -cp pdfbox-app-1.5.0.jar org.apache.pdfbox.ExtractImages 8086.pdf
2，PDF取得文本
public String getTextFromPDF(String pdfFilePath) {  
        String result = null;  
        FileInputStream is = null;  
        PDDocument document = null;  
        try {  
            is = new FileInputStream(pdfFilePath);  
            PDFParser parser = new PDFParser(is);  
            parser.parse();  
            document = parser.getPDDocument();  
            PDFTextStripper stripper = new PDFTextStripper();  
            result = stripper.getText(document); 
        } catch (FileNotFoundException e) {  
            e.printStackTrace();  
        } catch (IOException e) {  
            e.printStackTrace();  
        } finally {  
            if (is != null) {  
                try {  
                    is.close();  
                } catch (IOException e) {  
                    // TODO Auto-generated catch block  
                    e.printStackTrace();  
                }  
            }  
            if (document != null) {  
                try {  
                    document.close();  
                } catch (IOException e) {  
                    e.printStackTrace();  
                }  
            }  
        }  
        return result;  
    }
