txt,rtf,rtfd->pdf，mac下面有个非常好用的工具，TextEditor，简洁实用!

pdf->txt，如下(依赖两个jar 包：pdfbox-1.6.0.jar、fontbox-1.6.0.jar)：

package org.bruce.toolkit.experiments;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.OutputStreamWriter;

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

/**

public class Pdf2Text {

	/**

//		System.out.println(parsePDF("/Users/user/Desktop/QT教程.pdf"));
		System.out.println(parsePDF("/Users/user/Novels/pdf/《盗墓笔记》第一季：.第二部.怒海潜沙.pdf"));
	}

	/**
