Java实现Word转PDF方案选择

很多应用场景中都会涉及到Word转PDF，但Word转PDF的方案在网上一搜一大把，让人眼花缭乱，笔者踩过无数的坑后，最终总结出以下三种方案

OpenOffice实现Word转ODF
docx2pdf实现Word转ODF
itext+POI实现Word转ODF

方案

这种方案在Windows中可行，且非常简便，但它完全依赖于OpenOffice，想在Linux中实现，显然不是一个好的方案，笔者尝试过Linux中装OpenOffice，但令人发指的是居然还需要装GUI！

Java代码

import java.io.IOException;
import java.net.ConnectException;

import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection;

public class OfficetoPdfUtil {
	public static void createPDF(String sourceFile, String destFile) {
		// String OpenOffice_HOME = "D:/Program Files/OpenOffice.org 3";//
		// 这里是OpenOffice的安装目录,C:\Program Files (x86)\OpenOffice 4
		String OpenOffice_HOME = "D:\\openoffice\\newgay\\";
		Process pro = null;
		try {
			String command = OpenOffice_HOME
					+ "program\\soffice.exe -headless -accept=\"socket,host=127.0.0.1,port=8300;urp;StarOffice.ServiceManager\" -nofirststartwizard";
			pro = Runtime.getRuntime().exec(command);
			File inputFile = new File(sourceFile);
			// 如果目标路径不存在, 则新建该路径
			File outputFile = new File(destFile);
			if (!outputFile.getParentFile().exists()) {
				outputFile.getParentFile().mkdirs();
			}

			// connect to an OpenOffice.org instance running on port 8100
			OpenOfficeConnection connection = new SocketOpenOfficeConnection(
					"127.0.0.1", 8300);
			connection.connect();

			// convert
			DocumentConverter converter = new OpenOfficeDocumentConverter(
					connection);
			converter.convert(inputFile, outputFile);

			// close the connection
			connection.disconnect();
			pro.destroy();
		} catch (ConnectException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	public static void main(String[] args) {
		createPDF("C:\\Users\\Administrator\\Desktop\\test.doc", "C:\\Users\\Administrator\\Desktop\\test.pdf");
	}
}

这种方案在Windows和Linux中都可用，但有一点需要注意，它只支持07以上的Word转换，很不幸，笔者的Word模版是03的，只能用第三种方案了。事实上，这种方案中也依赖了Itext的包

这种方案也就是先解析Word，然后将内容转换到PDF中，是三种方案中最繁琐的选择，但如果你的Word模板不是07以上的，而线上环境是Linux，这是最后的选择了
