使用JODConverter轉換文檔爲PDF

1.JODConverter介紹：

        JODConverter automates conversions between office document formats using OpenOffice.org or LibreOffice.

        Supported formats include OpenDocument, PDF, RTF, HTML, Word, Excel, PowerPoint, and Flash.

        It can be used as a Java library, a command line tool, or a web application. 

JODConverter可以將一般格式的文檔轉換爲PDF格式。

2.示例

這裏用的是3.0的版本

OfficeManager officeManager = new DefaultOfficeManagerConfiguration().buildOfficeManager();
officeManager.start();

OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
converter.convert(new File("test.odt"), new File("test.pdf");

officeManager.stop();

如果你直接運行這些代碼的話，是不會成功的，報一個錯誤

Exception in thread "main" java.lang.IllegalStateException: officeHome not set and could not be auto-detected
    at org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration.buildOfficeManager(DefaultOfficeManagerConfiguration.java:163)
    at org.ygy.util.PDFUtil.toPDF(PDFUtil.java:11)
    at org.ygy.util.PDFUtil.main(PDFUtil.java:21)

要使用JODconverter需要安裝OpenOffice或者LibreOffice，我安裝了OpenOffice。

然後設置一下officeHome：

public static void toPDF() {
        OfficeManager officeManager = new DefaultOfficeManagerConfiguration()
                         .setOfficeHome("D:\\program files\\openoffice.org 3")
                         .buildOfficeManager();
        officeManager.start();

        OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
        converter.convert(new File("E:\\demo.doc"), new File("E:\\demo_1.pdf"));

        officeManager.stop();
    }

這下就可以了，之前用2.2的版本，需要手動的開一個服務：

public static void startServer() {
        String cmd = "cmd /k soffice -headless -accept=\"socket,host=127.0.0.1,port=8100;urp;\" -nofirststartwizard";
        try {
            Runtime.getRuntime().exec(cmd , null , new File("D:\\program files\\openoffice.org 3\\program"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

3.TXT轉換爲PDF

在將.txt文件轉換爲PDF的時候發現，如果TXT文件的編碼是ANSI的話，中文會產生亂碼，解決辦法是先將.txt保存爲.odt文件,再將.odt文件轉換爲PDF就可以了。

如果TXT文件的編碼是UTF-8的話，中文也可以正常轉換。

package org.ygy.util;

import java.io.File;

import org.artofsolving.jodconverter.OfficeDocumentConverter;
import org.artofsolving.jodconverter.office.DefaultOfficeManagerConfiguration;
import org.artofsolving.jodconverter.office.OfficeManager;

public class PDFUtil {
    public static void toPDF(String sourcePath , String targetpath) {
        if(sourcePath.endsWith(".txt")) {
            //先保存爲.odt
            StringBuffer odtPath = new StringBuffer(sourcePath.substring(0 , sourcePath.lastIndexOf(".")));
            odtPath.append(".odt");

            FileUtil.write(sourcePath , odtPath.toString());
            sourcePath = odtPath.toString();
        }
        OfficeManager officeManager = new DefaultOfficeManagerConfiguration()
                                        .setOfficeHome("D:\\program files\\openoffice.org 3")
                                        .buildOfficeManager();
        officeManager.start();

        OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
        converter.convert(new File(sourcePath), new File(targetpath));

        officeManager.stop();
    }

    public static void main(String[] args) {
        PDFUtil.toPDF("E:\\type.txt" , "E:\\type_2.pdf");
    }
}
