在JGit中记录变更历史记录

Question

我正在尝试使用JGit显示文件变更历史记录。我设法获取提交消息的历史记录。但不能得到与每个提交的更改（如git log -p），基本上我需要检查什么变化......（如+， - 日志命令）

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); 
    } 
}

解决在使用DiffFormatter http://codesnippetx.blogspot.com/

Answer 2

如果没有简单的方法来通过纯java LogCommand显示修补程序，您可以使用org.eclipse.jgit.pgm.Log类，它将调用包装为git。

作为包装，它确实有-p选项。
