The use of XStream's converter

Viewed on the Internet, there are few examples of the use of converter in XStream, here is a simple example of application

The file format is as follows:

<list> <mapper netype= "2g" > <sqlByType></sqlByType> <sqlById></sqlById> <types> <include>BTS</include> </types> </mapper> <mapper netype= "3g" > <types> <include>NODEB</include> </types> </mapper> </list>

The entity class is defined as follows:

@XStreamAlias ("Mapper") public class Netypemapper { @XStreamAsAttribute Public String Netype; @XmlElement Public String Sqlbytype; @XmlElement Public String Sqlbyid; @XStreamAlias ("Types") Public list<string> includetypes = new arraylist<string> (); }

Converter:

Static Class Listconverter extends Abstractcollectionconverter { Public Listconverter (Mapper Mapper) { Super (mapper); } @Override public boolean Canconvert (Class type) { Return Type.equals (Arraylist.class); } @Override public void Marshal (Object source, hierarchicalstreamwriter writer, Marshallingcontext context) { list<string> list = (list<string>) source; Listiterator<string> iter = List.listiterator (); String value = null; while (Iter.hasnext ()) { Value = Iter.next (); Extendedhierarchicalstreamwriterhelper.startnode (writer, "include", List.class); Writer.setvalue (value); Writer.endnode (); } } @Override Public Object Unmarshal (Hierarchicalstreamreader Reader, Unmarshallingcontext context) { String nodename = Reader.getnodename (); System.out.println (nodename); list<string> list = new arraylist<string> (); while (Reader.hasmorechildren ()) { Reader.movedown (); NodeName = Reader.getnodename (); System.out.println (nodename+ "-To" +reader.getvalue ()); List.add (Reader.getvalue ()); Reader.moveup (); } return list; } }

How to use:

XStream xs = new XStream (); Xs.processannotations (Netypemapper.class); Xs.registerlocalconverter (Netypemapper.class, "Includetypes", New Listconverter ( New Defaultmapper (XStream.class.getClassLoader ())); File File = new file (FilePath); FilePath: Path to File try { list<netypemapper> list = (list<netypemapper>) xs . FromXml (New FileInputStream (file));
