Obj2Xml.java(Obj를 받아서 Xml(String)으로 변환)

package com.exam.util.xstream;
 
import com.exam.domain.AuthKey;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;
import com.thoughtworks.xstream.io.xml.XmlFriendlyReplacer;
 
public class Obj2Xml {
    private Object obj;
    
    public Obj2Xml(Object obj){
        this.obj = obj;
    }
    
    public String toXml(){
        String toXml;
        
        XmlFriendlyReplacer replacer = new XmlFriendlyReplacer("__","_");
        XStream xStream = new XStream(new DomDriver("UTF-8", replacer)){
            protected boolean useXStreamXmlFriendlyMapper() {
                return true;
            }
        };
        xStream.alias("AuthKey", AuthKey.class);
        toXml = xStream.toXML(obj);
        return toXml;
    }
    
}

Result

===== XML OUT =====
 
  key
  a001122334455
  pro1
  pro2
 
===== JSON OUT =====
{"response":{"id":"a001122334455","property_1":"pro1","primaryKey":"key","property_2":"pro2"}}

Xstream 을 사용할때 Obj 속성중 _ 가 있으면 __ 로 변환 되기 때문에 아래처럼 XmlStream을 선언하여 써야 한다.

참고

XmlFriendlyReplacer replacer = new XmlFriendlyReplacer("__","_");
        XStream xStream = new XStream(new DomDriver("UTF-8", replacer)){
            protected boolean useXStreamXmlFriendlyMapper() {
                return true;
            }
        };
