XStream Convert map and List

Nonsense, is not want to define too many Java beans, sometimes the need is simpler, think directly with Java Collection class to replace too many Java bean definitions, see the following code example

Package org.garbagecan.xstreamstudy.converter;
Import java.util.ArrayList;
Import Java.util.HashMap;
Import java.util.List;

Import Java.util.Map;
Import Com.thoughtworks.xstream.XStream;

Import Com.thoughtworks.xstream.io.xml.DomDriver; public class Testmaplistconverter {@SuppressWarnings ({"Rawtypes", "Unchecked"}) public static void main (string[] args
		{XStream XStream = new XStream (new Domdriver ());
		
		Map map = new HashMap ();
		List List1 = new ArrayList ();
		List1.add (New T ("A1", "B1", "C1"));
		List1.add (New T ("A2", "B2", "C2"));
		List list2 = new ArrayList ();
		List2.add (New T ("A3", "B3", "C3"));
		List2.add (New T ("A4", "B4", "C4"));
		Map.put ("T1", List1);
		
		Map.put ("T2", list2);
		Xstream.alias ("Classes", Map.class);
		Xstream.alias ("Class", Map.Entry.class);
		
		Xstream.alias ("name", String.class);
		Xstream.alias ("Fields", list.class);
		Xstream.alias ("field", T.class);
		Xstream.aliasattribute (T.class, "a", "a"); Xstream.aliasattribute (T.class, "B", "B");
		Xstream.aliasattribute (T.class, "C", "C");

		SYSTEM.OUT.PRINTLN (Xstream.toxml (map));
	SYSTEM.OUT.PRINTLN (map) xstream.fromxml (xstream.toxml (map));
		Class T {public T (string A, string B, string c) {this.a = A;
		this.b = b;
	THIS.C = C;
	} private String A;
	Private String B;
	Private String C;
	Public String Geta () {return A;
	} public void SetA (String a) {this.a = A;
	Public String Getb () {return b;
	public void Setb (String b) {this.b = b;
	Public String getc () {return C;
	public void SetC (String c) {this.c = C; @Override public String toString () {return org.apache.commons.lang.builder.ToStringBuilder.reflectionToString
	);
 }
}

Run the example above to get the XML inside as follows:

<classes>
  <class>
    <name>t2</name>
    <fields>
      <field a= "A3" b= "B3" C= "C3"/>
      <field a= "A4" b= "B4" c= "C4"/>
    </fields>
  </class>
  <class>
    <name>t1</name>
    <fields>
      <field a= "A1" b= "B1" c= "C1"/> <field a=
      "A2" b= "B2" "c=" C2 "/>
    </fields>
  </class>
</classes>

The contents of the resulting Java object are as follows:

{T2=[ORG.GARBAGECAN.XSTREAMSTUDY.CONVERTER.T@B166B5[A=A3,B=B3,C=C3], org.garbagecan.xstreamstudy.converter.t@ 1837697[A=A4,B=B4,C=C4]], T1=[ORG.GARBAGECAN.XSTREAMSTUDY.CONVERTER.T@1DECDEC[A=A1,B=B1,C=C1], ORG.GARBAGECAN.XSTREAMSTUDY.CONVERTER.T@A1807C[A=A2,B=B2,C=C2]]}
