itext java.lang.NoClassDefFoundError: DefaultAccessibilityProperties

Question

我不明白为什么我在这个非常基本的 iText 测试中遇到异常：

package com.itextpdf.testpdf4;
import com.itextpdf.io.font.FontConstants;
import com.itextpdf.kernel.font.PdfFont;
import com.itextpdf.kernel.font.PdfFontFactory;
import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.layout.Document;
import com.itextpdf.layout.element.List;
import com.itextpdf.layout.element.ListItem;
import com.itextpdf.layout.element.Paragraph;

import com.itextpdf.text.DocumentException;
import com.itextpdf.licensekey.LicenseKey;
import com.itextpdf.test.annotations.WrapToTest;

import java.io.File;
import java.io.IOException;

@WrapToTest
public class HelloWorld {


    public static final String DEST = "result/hello.pdf";

    public static void main(String[] args)
        throws DocumentException, IOException {

        LicenseKey.loadLicenseFile("C:\\dev\\testPDF4\\src\\main\\java\\com\\itextpdf\\testpdf4\\itextkey1544447451310_0.xml");

        File file = new File(DEST);
        file.getParentFile().mkdirs();
        new HelloWorld().createPdf(DEST);

    }




    public void createPdf(String dest) throws DocumentException, IOException {
        PdfWriter writer = new PdfWriter(dest);

        //Initialize PDF document
        PdfDocument pdf = new PdfDocument(writer);

        // Initialize document
        Document document = new Document(pdf);

 // Create a PdfFont
        PdfFont font = PdfFontFactory.createFont(FontConstants.TIMES_ROMAN);
        // Add a Paragraph
        document.add(new Paragraph("iText is:").setFont(font));
        // Create a List
        List list = new List()
            .setSymbolIndent(12)
            .setListSymbol("\u2022")
            .setFont(font);
        // Add ListItem objects
        list.add(new ListItem("Never gonna give you up"))
            .add(new ListItem("Never gonna let you down"))
            .add(new ListItem("Never gonna run around and desert you"))
            .add(new ListItem("Never gonna make you cry"))
            .add(new ListItem("Never gonna say goodbye"))
            .add(new ListItem("Never gonna tell a lie and hurt you"));
        // Add the list
        document.add(list);

        //Close document
        document.close();
    }
}

线程“主”java.lang.NoClassDefFoundError 中的异常： com/itextpdf/kernel/pdf/tagutils/DefaultAccessibilityProperties 在 com.itextpdf.testpdf4.HelloWorld.createPdf(HelloWorld.java:56)

(第 56 行是：document.add(new Paragraph("iText is:").setFont(font));)

这段代码来自这里：https://developers.itextpdf.com/fr/content/itext-7-jump-start-tutorial/examples/chapter-1 -> C01E02_RickAstley.java

在 POM.XML 中：

  <modelVersion>4.0.0</modelVersion>
    <groupId>com.itextpdf</groupId>
    <artifactId>testPDF4</artifactId>
    <version>1.0</version>

（包是：包com.itextpdf.testpdf4;）

有人看出什么不对了吗？我没有

谢谢

Answer 1

您正在混合不同的核心 itext 工件版本，7.0.4 和 7.1.4。

    ...
    <dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>io</artifactId>
        <version>7.0.4</version>
    </dependency>
    <dependency>
        <groupId>com.itextpdf</groupId>
        <artifactId>layout</artifactId>
        <version>7.1.4</version>
        <type>jar</type>
    </dependency>
    ...

不要混合这些。使用所有核心 itext 工件的相同版本。

顺便说一下，你把你的测试项目放到了itext组里：

<groupId>com.itextpdf</groupId>
<artifactId>testPDF4</artifactId>

您不应该这样做，尤其是在生产使用项目中。
