        public static void main(String[] args){
            Date startDate = new Date();
            String sourceFile = "d:\\code\\alipay.ppt";
            String destFile = "d:\\code\\change2.pdf";
            System.out.println(Office2PDF.office2PDF(sourceFile, destFile));
            Date endDate = new Date();
            System.out.println("the cost time is "+(endDate.getTime()-startDate.getTime()));
        }
    }      

先运行

soffice --headless --accept="socket,host=127.0.0.1,port=8100;urp;"

soffice 在LibreOffice安装目录下

如果出现下面的异常

com.artofsolving.jodconverter.openoffice.connection.OpenOfficeException: conversion failed: could not load input document

尽量使用最新的LibreOffice
