Question

我正在尝试使用Java从HTML创建PDF文件。我添加了两个jar文件。

itextpdf-5.1.0
xmlworker-5.5.6

我的代码：

import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;
    String emailBody = "<html><body> This is my Project </body></html>";

    OutputStream file = new FileOutputStream(new File("E:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(emailBody.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();

我从这一行得到了一个错误：

XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);

它抛出了我这个例外。我正在寻找解决方案。

感谢。

Answer 1

很可能它们彼此不相容。请尝试使用以下最新版本xmlworker-5.5.13.jar，itextpdf-5.5.13.jar

Answer 2

你真的与这两个库有冲突。您必须将Loggeer的传递依赖性排除在其中一个之外。

您使用什么构建工具？与maven，gradle等

相同

请参阅https://maven.apache.org/guides/introduction/introduction-to-optional-and-excludes-dependencies.html或https://docs.gradle.org/current/userguide/managing_transitive_dependencies.html
