How do I encode UTF-8 using the XStream framework?

问题:

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?

Thanks!

回答1:

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"); 

You may also use that Writer to include the XML Declaration.

writer.write(""); 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:

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...

With a current version of XStream, @Jeromy's example would look like this:

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");
