使用ApacheTika检测文件扩展名会损坏文件

import org.apache.tika.Tika;
import java.io.File;
import java.io.IOException;

public class FileExtensionDetector {
    public static void main(String[] args) {
        File file = new File("path/to/your/file");
        Tika tika = new Tika();
        
        try {
            String fileExtension = tika.detect(file);
            System.out.println("File extension: " + fileExtension);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
