如何使用Java pdfutil比较PDF文件

import org.zefer.pdftools.PdfComparator;

public class PdfComparisonExample {
    public static void main(String[] args) {
        String file1Path = "path/to/file1.pdf";
        String file2Path = "path/to/file2.pdf";

        PdfComparator comparator = new PdfComparator();
        comparator.setIgnoreWhitespace(true);
        comparator.setIgnoreFont(true);

        boolean isEquals = comparator.compare(file1Path, file2Path);

        if (isEquals) {
            System.out.println("PDF 文件相同");
        } else {
            System.out.println("PDF 文件不同");
            System.out.println("差异的页数：" + comparator.getDiffPageCount());
            System.out.println("差异的内容：" + comparator.getDiffContent());
        }
    }
}
