java - 将 .docx 转换为 .pdf

问题描述

我正在尝试使用 Apache POI 将 docx 转换为 pdf。我看到了很多关于这个问题的问题，但即使是最好的答案也不起作用。我已经尝试将版本更改为最旧的版本 - 没有结果。我使用 Kotlin 和 Gradle。主类代码如下：

import org.apache.poi.xwpf.converter.pdf.PdfConverter
import org.apache.poi.xwpf.converter.pdf.PdfOptions
import org.apache.poi.xwpf.usermodel.XWPFDocument
import java.io.*


class o {
    fun ConvertToPDF(docPath: String?, pdfPath: String?) {
            val doc = FileInputStream(File(docPath!!))
            val document = XWPFDocument(doc)
            val options = PdfOptions.create()
            val out = FileOutputStream(File(pdfPath!!))
            PdfConverter.getInstance().convert(document, out, options)
    }

    companion object {
        @JvmStatic
        fun main(args: Array<String>) {
            val cwoWord = o()
            println("Start")
            cwoWord.ConvertToPDF("C:\\simple.docx",
                "123.pdf")
        }
    }
}

带有依赖项的 build.gradle

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"

    implementation "org.apache.poi:poi-ooxml-schemas:4.1.0"
    implementation "fr.opensagres.xdocreport:org.apache.poi.xwpf.converter.core:1.0.6"
    implementation "fr.opensagres.xdocreport:org.apache.poi.xwpf.converter.pdf:1.0.6"
    implementation "fr.opensagres.xdocreport:fr.opensagres.xdocreport.itext.extension:2.0.0"
    implementation "com.lowagie:itext:2.1.7"
    implementation "org.apache.poi:ooxml-schemas:1.4"
    implementation "org.apache.xmlbeans:xmlbeans:3.1.0"
    implementation "org.dom4j:dom4j:2.1.1"
    implementation "org.apache.poi:poi-ooxml:4.1.0"
    implementation "org.apache.poi:poi:4.1.0"   

    testCompile group: 'junit', name: 'junit', version: '4.12'
}

错误：
