Question

我正在使用以下代码从JGIT repo中检索文件：

public class JGitPrintContent3
{
    public static void main(String[] args) throws Exception
    {
        File gitWorkDir = new File("D:/jboss/server/repo/Repository/");
        Git git = Git.open(gitWorkDir);
        Repository repo = git.getRepository();

        ObjectId lastCommitId = repo.resolve("b35fd0300270e6ba4d9238a1ab328b25a627885a");//userFile.sql

        System.out.println("Points to : " + lastCommitId.name());

        RevWalk revWalk = new RevWalk(repo);
        RevCommit commit = revWalk.parseCommit(lastCommitId);
        revWalk.markStart(commit);

        RevTree tree = commit.getTree();
        TreeWalk treeWalk = new TreeWalk(repo);
        treeWalk.addTree(tree);
        treeWalk.setRecursive(true);
        treeWalk.setFilter(PathFilter.create("userFile.sql"));

        ObjectId objectId = treeWalk.getObjectId(0);
        System.out.println(" objectId : " + objectId );
        ObjectLoader loader = repo.open(objectId);

        File targetFile = new File("C:\\temp\\gittest\\target2\\" + "userFile.sql");
        OutputStream out = new FileOutputStream(targetFile);
        loader.copyTo(out);
        out.flush();
        out.close();

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

但不幸的是，它正在检索先前检索的（提交ID）内容的文件内容。

我非常感谢你的帮助。

谢谢。 ~Shyam * /

您已在代码中对提交进行了硬编码，因此您将始终获得该值。

ObjectId lastCommitId = repo.resolve("b35fd0300270e6ba4d9238a1ab328b25a627885a");//userFile.sql

如果您想将其基于当前分支，请使用repo.resolve("HEAD")

另请注意，此处不需要您的RevCommit;如果您想要获取当前树，请改用repo.resolve("HEAD^{tree}")。

无法使用commitID检索正确的文件内容
