java - 带有特殊字符的 Xstream

Question

我正在使用 XStream，但我在使用特殊字符 á、é、í、ó、ú 和 ñ 时遇到问题。

我尝试过这个:

  String charset = "UTF-8";
  xstream = new XStream(new DomDriver(charset));

(不起作用)

我发现XStream does no character encoding by itself, it relies on the configuration of the underlying XML writer. By default it uses its own PrettyPrintWriter which writes into the default encoding of the current locale. To write UTF-8 you have to provide a Writer with the appropriate encoding yourself.

我的问题是我不知道如何提供 Writer...

// get the model from the map passed created by the controller
Object model = map.get("model");

Object viewData = transformViewData(model);

//TEST
Writer w = new OutputStreamWriter(viewData, "UTF-8");
//FINTEST

// if the model is null, we have an exception
String xml = null;
if (viewData != null){
    xml = xstream.toXML(viewData, w);  //Err:Cannot find symbol...
}else{
    // so render entire map
    xml = xstream.toXML(map, w); //Err:Cannot find symbol...
}

response.getOutputStream().write(xml.getBytes());

这是 right there in the javadoc .

Writer w = new OutputStreamWriter(new FileOutputStream("test.xml"), "UTF-8");
XStream.toXML(object, w);
