公共 FileUtils 看起来很酷，我不敢相信它们不能附加到文件中.

The commons FileUtils look pretty cool, and I can't believe that they cannot be made to append to a file.

File file = new File(path);
FileUtils.writeLines(file, printStats(new DateTime(), headerRequired));

上面只是每次都替换文件的内容，我只想像这段代码一样继续标记这些东西以结束.

The above just replaces the contents of the file each time, and I would just like to keep tagging this stuff to end just as this code does.

fw = new FileWriter(file, true);
try{
    for(String line : printStats(new DateTime(), headerRequired)){
        fw.write(line + "
");
    }
}
finally{ 
    fw.close();
}

我已经搜索了 javadoc，但什么也没找到！我错过了什么?

I've searched the javadoc but found nothing! What am I missing?

推荐答案

你可以使用IOUtils.writeLines()，它接收一个 Writer 对象，你可以像你的第二个例子一样初始化.

You can use IOUtils.writeLines(), it receives a Writer object which you can initialize like in your second example.
