如何使用XStream框架编码UTF-8?
问题描述：
根据XStream的常见问题解答，其默认解析器不保留UTF-8文档编码，并且必须提供自己的编码器.如何做到这一点?
Per XStream's FAQ its default parser does not preserve UTF-8 document encoding, and one must provide their own encoder. How does one do this?
谢谢！
答
使用UTF-8编码创建Writer.将Writer作为参数传递给XStream的toXML方法.
Create a Writer with UTF-8 encoding. Pass the Writer as an argument to XStream's toXML method.
XStream xstream = new xStream();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Writer writer = new OutputStreamWriter(outputStream, "UTF-8");
xStream.toXML(object, writer);
String xml = outputStream.toString("UTF-8");
您还可以使用该Writer来包含XML声明.
You may also use that Writer to include the XML Declaration.
writer.write("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>");
xStream.toXML(object, writer);
