使用apose实现doc转pdf或者pdf转doc，同时支持目录检测

package com.word;

public class Word2PdfUtil {

    static final int wdDoNotSaveChanges = 0;// 不保存待定的更改。
    static final int wdFormatPDF = 17;// word转PDF 格式

    public static void main(String[] args) throws IOException {
        String source1 = "C:\aa.docx";
        String target1 = "C:\bb.pdf";
        Word2PdfUtil.word2pdf(source1, target1);
    }

    
    public static boolean word2pdf(String source, String target) {

            File tofile = new File(target);
            if (tofile.exists()) {

            }
            Dispatch.call(doc, "SaveAs", target, wdFormatPDF);
