How do I encode UTF-8 using the XStream framework?
提问by Jeromy Evans
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?
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？
Thanks!
谢谢！

Create a Writer with UTF-8 encoding. Pass the Writer as an argument to XStream's toXML method.
使用 UTF-8 编码创建一个 Writer。将 Writer 作为参数传递给 XStream 的 toXML 方法。
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");
You may also use that Writer to include the XML Declaration.
您还可以使用该 Writer 来包含 XML 声明。
writer.write("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>");
xStream.toXML(object, writer);

Another solution would be to initiate the XStream-object with correct encoding, through a driver. Using the DomDriver this would look like:
另一种解决方案是通过驱动程序以正确的编码启动 XStream 对象。使用 DomDriver 这看起来像：
XStream xstream = new XStream(new DomDriver("UTF-8"));
The (default) PrettyPrintWriter will be wrapped by an outputstream with correct encoding. You could not add the UTF-8 header this way however...
（默认）PrettyPrintWriter 将由具有正确编码的输出流包装。但是，您无法以这种方式添加 UTF-8 标头...

With a current version of XStream, @Jeromy's example would look like this:
使用当前版本的 XStream，@Jeromy 的示例如下所示：
ByteArrayOutputStream stream = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(stream, "UTF-8");
HierarchicalStreamWriter xmlWriter = new PrettyPrintWriter(writer);
xstream.marshal(object, xmlWriter);
return new String(stream.toByteArray(), "UTF-8");
