XStream解析[以支付宝解析为列子]

XStream 

 Xstream是一种OXMapping 技术，是用来处理XML文件序列化的框架,在将JavaBean序列化，或将XML文件反序列化的时候，不需要其它辅助类和映射文件，使得XML序列化不再繁索。Xstream也可以将JavaBean序列化成Json或反序列化，使用非常方便。

首先介绍几个常用的注解:

1.@XStreamAlias("")  别名,对应xml中节点名称

2.@XStreamAsAttribute   把字段节点设置成属性

3.@XStreamImplicit 省略集合根节点,当遇到list集合可以使用此注解.

4.@XStreamOmitField 隐藏字段 

5.设置转换器：@XStreamConverter()

列:

1. @XStreamConverter(value=BooleanConverter.class,booleans={false},strings={"男","女"})
2. privateboolean sex;

下面贴上使用xstream解析支付宝账单xml实列

2.建立解析测试demo

package xmlParser.xStream;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import com.thoughtworks.xstream.XStream;import com.thoughtworks.xstream.io.xml.DomDriver;public class XmlParser {public static <T> T XML2Bean(String xml, Class<T> clazz) throws IOException {XStream xstream = new XStream(new DomDriver());xstream.processAnnotations(clazz);return (T) xstream.fromXML(xml);}public static <T> T XML2Bean(InputStream input, Class<T> clazz)throws IOException {XStream xstream = new XStream(new DomDriver());xstream.processAnnotations(clazz);return (T) xstream.fromXML(input);}public static String XML2Bean(Object obj)throws IOException {XStream xstream = new XStream(new DomDriver());return  xstream.toXML(obj);}public static void main(String[] args) {InputStream inputStream=null;try {String path=Thread.currentThread().getContextClassLoader().getResource("").getPath();System.out.println(path);inputStream=new FileInputStream(new File(path+"\\xmlParser\\xStream\\ali.xml"));AlipayAccountPageQuery xml2Bean = XML2Bean(inputStream, AlipayAccountPageQuery.class);//任意打印一个字段值测试.System.out.println(xml2Bean.getRequest().getParam().get(0).getContent());// xml也可以反序列化String xml2Bean2 = XML2Bean(xml2Bean);System.out.println(xml2Bean2);} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}finally{try {if (inputStream!=null) {inputStream.close();}} catch (IOException e) {e.printStackTrace();}}}}

至此解析完毕
