XMLENCODER是一个可以将一个JAVA对象以XML方式存储，在需要再次使用该对象时候可以使用XMLDECODER进行还原，比JAVA对象流好用.

测试程序：

package com.sitechasia.test.beans;

import java.io.OutputStream;

import junit.framework.TestCase;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.funambol.framework.engine.source.ContentType;
import com.funambol.framework.engine.source.SyncSourceInfo;
import com.sitechasia.test.tools.BeanXmlEncoder;
import com.sitechasia.uab.sync.source.UabSyncSource;

public class TestBeanXmlEncoder extends TestCase {

public TestBeanXmlEncoder(String arg0) {
super(arg0);
}

protected void setUp() throws Exception {
super.setUp();
}

Log log = LogFactory.getLog(TestBeanXmlEncoder.class);

public void testEncodeUabSyncSource() {
  OutputStream beanout = System.out;
  UabSyncSource us = null;
  try {
   us = new UabSyncSource();
   us.setDebug(true);
   us.setName("card3");
   us.setSourceURI("card3");

   SyncSourceInfo info = null;
   ContentType[] cts = new ContentType[3];
   cts[0] = new ContentType("text/vcard", "2.1");
   cts[1] = new ContentType("text/x-vcard", "2.1");
   cts[2] = new ContentType("text/plain", "2.1");
   info = new SyncSourceInfo(cts, 1);
   us.setInfo(info);

BeanXmlEncoder.EncoderBean(us, beanout);

  } catch (Exception e) {
   System.out.println("Fail to sav Bean");
  }
}

protected void tearDown() throws Exception {
super.tearDown();
}

}

工具类：

package com.sitechasia.test.tools;

import java.beans.XMLEncoder;
import java.io.OutputStream;

import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.exception.ExceptionUtils;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

/**
* 对一个JAVA类进行编码保存
* @author MCSA
*
*/
public class BeanXmlEncoder {
final static Log log = LogFactory.getLog(BeanXmlEncoder.class);
public static void EncoderBean(Object bean, OutputStream beanstore) {
  XMLEncoder encoder = null;
  try {
   encoder = new XMLEncoder(beanstore);
   encoder.writeObject(bean);
   encoder.flush();
   encoder.close();
  } catch (Exception e) {
   log.error("Fail Encode bean"+ToStringBuilder.reflectionToString(bean));
   log.error("---------------------------------------------------------
");
   log.error(ExceptionUtils.getStackTrace(e));
  }

}
