1. 编写简单的POJO，并添加基本的注解，类似于JPA，只有被@XmlRootElement标注的类才会处理：

package org.jack.jaxb;import javax.xml.bind.annotation.XmlRootElement;/** @author 李文锴*/@XmlRootElementpublic class Jack {private String firstName;private String lastName;public String getFirstName() {return firstName;}public void setFirstName(String firstName) {this.firstName = firstName;}public String getLastName() {return lastName;}public void setLastName(String lastName) {this.lastName = lastName;}}

2. 编写测试类，进行POJO与XML的转换：

package org.jack.jaxb;</p> <p>import java.io.StringReader;<br /> import java.io.StringWriter;</p> <p>import javax.xml.bind.JAXBContext;<br /> import javax.xml.bind.Marshaller;<br /> import javax.xml.bind.Unmarshaller;</p> <p>public class JAXBTest {</p> <p> public static void main(String[] args) throws Exception {<br /> JAXBContext context = JAXBContext.newInstance(Jack.class);<br /> Marshaller marshaller = context.createMarshaller();<br /> Unmarshaller unmarshaller = context.createUnmarshaller();</p> <p> Jack jack = new Jack();<br /> jack.setFirstName("jack");<br /> jack.setLastName("lee");</p> <p> StringWriter writer = new StringWriter();<br /> marshaller.marshal(jack, writer);<br /> System.out.println(writer.toString());</p> <p> String xml = "<jack><firstName>first</firstName><lastName>last</lastName></jack>";<br /> Jack xj = (Jack) unmarshaller.unmarshal(new StringReader(xml));<br /> System.out.println(xj.getFirstName());<br /> System.out.println(xj.getLastName());<br /> }</p> <p>}<br />

3. 查看输出结果：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><jack><firstName>jack</firstName><lastName>lee</lastName></jack><br /> first<br /> last<br />
