我正在尝试使用 JGit 显示文件更改历史记录。我设法获得了提交消息的历史记录。但是无法获得与每个提交相关的更改（例如 git log -p），基本上我需要检查更改是什么...（例如 + ， - 在 log 命令中）
public void test() {
try {
File gitWorkDir = new File("/home/test/GITTEST/");
Git git = null;
git = Git.open(gitWorkDir);
Repository repo = git.getRepository();
LogCommand log = git.log();
log.setMaxCount(2);
Iterable<RevCommit> logMsgs = log.call();
for (RevCommit commit : logMsgs) {
System.out.println("----------------------------------------");
System.out.println(commit);
System.out.println(commit.getAuthorIdent().getName());
System.out.println(commit.getAuthorIdent().getWhen());
System.out.println(" ---- " + commit.getFullMessage());
System.out.println("----------------------------------------");
RevTree tree = commit.getTree();
TreeWalk treeWalk = new TreeWalk(repo);
treeWalk.addTree(tree);
treeWalk.setRecursive(true);
treeWalk.setFilter(TreeFilter.ANY_DIFF);
//treeWalk.setFilter(PathFilter.create("."));
if (!treeWalk.next())
{
System.out.println("Nothing found!");
return;
}
ObjectId objectId = treeWalk.getObjectId(0);
ObjectLoader loader = repo.open(objectId);
ByteArrayOutputStream out = new ByteArrayOutputStream();
loader.copyTo(out);
System.out.println("----" + out.toString());
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>----------------------------------------");
}
} catch (Exception e) {
System.out.println("no head exception : " + e);
}
}
