如何在Java中将InputStream转换为PDF，而不损坏文件？

<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.26</version>
</dependency>

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class InputStreamToPDFConverter {
    public static void convert(InputStream inputStream, String outputPath) throws IOException {
        PDDocument document = new PDDocument();
        PDPage page = new PDPage();
        document.addPage(page);

        // 从InputStream中读取数据并写入PDF文档
        document.save(outputPath);

        document.close();
        inputStream.close();
    }

    public static void main(String[] args) {
        try {
            InputStream inputStream = // 获取输入流，例如从文件或网络中读取
            String outputPath = // 输出PDF文件的路径
            convert(inputStream, outputPath);
            System.out.println("转换成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
