以使用它把Javabean转换成XML并输出。
下载地址：http://commons.apache.org/beanutils/
代码如下：
Javabean：package demo.bean;public class Music ...{ private String name; private String mp3File; public String getName() ...{ return name; } public void setName(String name) ...{ this.name = name; } public String getMp3File() ...{ return mp3File; } public void setMp3File(String mp3File) ...{ this.mp3File = mp3File; }}
测试代码：
package demo;import java.beans.IntrospectionException;import java.io.FileWriter;import java.io.IOException;import java.io.Writer;import org.apache.commons.betwixt.io.BeanWriter;import org.xml.sax.SAXException;import demo.bean.Music;public class BetwixtDemo ...{ public static void main(String[] args) throws IOException, SAXException, IntrospectionException ...{ Music music = new Music(); music.setName("music_name"); music.setMp3File("music_mp3file"); Writer utputWriter = new FileWriter("e:/test.xml"); BeanWriter beanWriter = new BeanWriter(outputWriter); beanWriter.getXMLIntrospector().getConfiguration().setAttributesForPrimitives(false); beanWriter.getBindingConfiguration().setMapIDs(false); beanWriter.enablePrettyPrint(); beanWriter.setEndTagForEmptyElement(true); beanWriter.setIndent(" "); beanWriter.writeXmlDeclaration(""); beanWriter.write("Msg", music); outputWriter.close(); }}
可指定NameMapper来重新定义大小写
beanWriter.getXMLIntrospector().getConfiguration().setElementNameMapper(new org.apache.commons.betwixt.strategy.DecapitalizeNameMapper());
其中：
DecapitalizeNameMapper 指定义小写
CapitalizeNameMapper 指定为大写
HyphenatedNameMapper 指定为连接符 比如mp3File ==> mp3-file
可以通过HyphenatedNameMapper.setUpperCase(true)设置首字母的大小写
也可实现NameMapper来定义自己的现实方式
如：class ItsANameMapper implements NameMapper { …… }
快乐要懂得分享，才能加倍的快乐
