itext java.lang.NoClassDefFoundError: DefaultAccessibilityProperties

Question

我不明白为什么在iText的这个非常基本的测试中会出现异常：

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"main“中的异常: com/itextpdf/kernel/pdf/tagutils/DefaultAccessibilityProperties at com.itextpdf.testpdf4.HelloWorld.createPdf(HelloWorld.java:56)

(第56行是:document.add(新的段落(“iText is：”).setFont(字体))；

有人看到什么不对劲了吗？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>
    ...

别把这些混在一起。使用所有核心itext工件的相同版本。

顺便说一句，您将您的测试项目放入itext组：

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

您不应该这样做，特别是在生产使用项目中。
