java操作pdf文件

要读取pdf文件,必须有pdfbox1.7.1.jar和fontbox1.7.1.jar,可以到官网下,也可以到我的资源里下,下面代码

import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;

public class Mytest {
	public static String getText(String file) {
		String s = "";
		String pdffile = file;
		PDDocument pdfdoc = null;
		try {
			pdfdoc = PDDocument.load(pdffile);
			PDFTextStripper stripper = new PDFTextStripper();
			s = stripper.getText(pdfdoc);
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try {
				if (pdfdoc != null) {
					pdfdoc.close();
				}
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		return s;
	}

	public static void toTextFile(String doc, String filename) throws Exception {
		String pdffile = doc;
		PDDocument pdfdoc = null;
		PrintWriter pw = null;
		try {
			pdfdoc = PDDocument.load(pdffile);
			PDFTextStripper stripper = new PDFTextStripper();
			pw = new PrintWriter(new FileWriter(filename));
			stripper.writeText(pdfdoc, pw);

		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			try {
				if(pw!=null){
					pw.close();
				}
				if (pdfdoc != null) {
					pdfdoc.close();
				}
			} catch (IOException e) {
				e.printStackTrace();
			}
		}

	}

	public static void main(String[] args) {
		try {
			String sc = getText("在这里输入要转换的pdf文件路径");
			System.out.print(sc);
			toTextFile("在这里输入要转换的pdf文件路径",
					"要保存的txt文件路径");
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

}
