java追加到文件 [英] java append to file

问题描述

我用谷歌搜索了一段时间，但似乎无法找到它，它应该很容易。我想将CR附加到我用Transformer创建的XML文件的末尾。有没有办法做到这一点>

I googled for this for a while but can't seem to find it and it should be easy. I want to append a CR to then end of an XML file that I am creating with a Transformer. Is there a way to do this>

我尝试了以下但是这导致了一个空白文件？

I tried the following but this resulted in a blank file?

Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "file:///ReportWiz.dtd");
xformer.transform(source, result);
OutputStream writer = new FileOutputStream(file);
Byte b = '\n';
writer.write(b);
writer.close();

推荐答案

简单......只是添加追加选项：

Simple... just add the append option:

    new FileOutputStream(f, true /* append */);
