Question

我是 Java 的新手，我正在研究从 html 生成 pdf。因此，我使用的是 iText7，我可以通过 PdfWriter 和 Document 生成一个普通的 pdf 文件，但我不能使用 html2pdf.

这是我的 Pom.xml

这是我的代码 java:

import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.Paths;

import com.itextpdf.html2pdf.HtmlConverter;

public class HtmlToPdf {

/** The HTML-string that we are going to convert to PDF. */
public static final String HTML = "<h1>Test</h1><p>Hello World</p>";
/** The target folder for the result. */
public static final String TARGET = "target/";
/** The path to the resulting PDF file. */
public static final String DEST = String.format("%stest-01.pdf", TARGET);

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

            HtmlConverter.convertToPdf(HTML, new FileOutputStream(DEST));

            System.out.println("Done");
        }
    }

错误在线：

HtmlConverter.convertToPdf(HTML, new FileOutputStream(DEST));
