　　XStream,Jackson

　　JAXB:

JAXB執行個體：

package com.bling.xml;import java.io.StringReader;import javax.xml.bind.JAXBContext;import javax.xml.bind.JAXBException;import javax.xml.bind.Marshaller;import javax.xml.bind.Unmarshaller;import org.junit.Test;public class TestJaxb {    @Test    public void test01(){        try {            JAXBContext ctx = JAXBContext.newInstance(Student.class);            Marshaller marshaller = ctx.createMarshaller();            Student stu = new Student(1,"楊明亮",21,new Classroom(1,"電腦",2014));            marshaller.marshal(stu, System.out);        } catch (JAXBException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    @Test    public void test02(){        String xml ="<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><student><age>21</age><classroom><grade>2014</grade><id>1</id><name>電腦</name></classroom><id>1</id><name>楊明亮</name></student>";        JAXBContext ctx;        try {            ctx = JAXBContext.newInstance(Student.class);            Unmarshaller um = ctx.createUnmarshaller();            Student stu = (Student)um.unmarshal(new StringReader(xml));            System.out.println("student name:"+stu.getName());        } catch (JAXBException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
