在 linux 中使用 java 将 RTF 格式转换为 PDF 格式

Question

我创建了一个 Java 代码来将 RTF 格式文档转换为 PDF 格式。程序在 windows 中正常运行。但它在 linux 中给出了错误。有人可以告诉我这段代码的问题吗？

Java代码：

import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
import java.io.*;

public class Main {
    public static void main(String[] args) {
        File inputWord = new File("sample.rtf");
        File outputFile = new File("sample.pdf");
        try  {
            InputStream docxInputStream = new FileInputStream(inputWord);
            OutputStream outputStream = new FileOutputStream(outputFile);
            IConverter converter = LocalConverter.builder().build();
            converter.convert(docxInputStream).as(DocumentType.RTF).to(outputStream).as(DocumentType.PDF).execute();
            outputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

我使用 documents4j 版本 1.1.3 来实现此代码。

linux 环境中出现以下错误：

Answer 1

您正在使用 com.documents4j.LocalConverter 对象执行转换。根据 documentation:

A LocalConverter can only be run if:

The JVM is run on a MS Windows platform that ships with the Microsoft Scripting Host for VBS (this is true for all contemporary versions of MS Windows.

MS Word is installed in version 2007 or higher. PDF conversion is only supported when the PDF plugin is installed. The plugin is included into MS Word from Word 2010 and higher.

etcetera

显然，Linux 机器无法满足这些先决条件。

您的选择似乎是：

使用 RemoteConverter 获取远程 Windows 机器进行转换。
寻找可在 Linux 上运行的替代 RTF 到 PDF 转换器。
