一个使用JAVA xmlencoder 例子
2023-06-30 16:35:34
XMLENCODER可以以XML的形式存储JAVA对象,当需要再次使用时,可以使用XMLDECODER进行恢复,比JAVA对象流更容易使用.
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; /** * 编码并保存JAVA类 * @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)); } } }
