如何使用JGit获取存储库中文件的时间戳？

import org.eclipse.jgit.api.Git;
import org.eclipse.jgit.lib.Repository;
import org.eclipse.jgit.revwalk.RevCommit;
import org.eclipse.jgit.revwalk.RevObject;
import org.eclipse.jgit.revwalk.RevWalk;
import org.eclipse.jgit.treewalk.TreeWalk;

import java.io.IOException;

public class JGitExample {
    public static void main(String[] args) throws IOException {
        // 打开一个本地的Git存储库
        Repository repository = Git.open(new File("/path/to/repository/.git")).getRepository();

        // 创建RevWalk对象
        try (RevWalk revWalk = new RevWalk(repository)) {
            // 获取最新的提交
            RevCommit commit = revWalk.parseCommit(repository.resolve("HEAD"));

            // 创建TreeWalk对象
            try (TreeWalk treeWalk = new TreeWalk(repository)) {
                // 将提交的文件树添加到TreeWalk中
                treeWalk.addTree(commit.getTree());

                // 遍历文件树
                while (treeWalk.next()) {
                    // 获取文件的路径
                    String path = treeWalk.getPathString();

                    // 获取文件的对象ID
                    ObjectId objectId = treeWalk.getObjectId(0);

                    // 解析文件的RevObject对象
                    RevObject object = revWalk.parseAny(objectId);

                    // 获取文件的时间戳
                    int timestamp = object.getCommitTime();

                    // 输出文件的路径和时间戳
                    System.out.println("File: " + path);
                    System.out.println("Timestamp: " + timestamp);
                }
            }
        }
    }
}
