本文主要讲述：使用jaxb完成对象和xml之间的转换

TestJava2xml.java如下所示：

package com.tgb.jaxb.v1;
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 TestJava2xml {
    // 测试：Java文件转化为Xml文件
    @Test
    public void testJava2Xml() {
        try {
            JAXBContext ctx = JAXBContext.newInstance(Student.class);
            // 用于Java文件转化为Xml文件的类
            Marshaller marshaller = ctx.createMarshaller();
            Student student = new Student(1001, "赵栗婧", 20, new Classroom(10,
                    "10级生命科学与工程", 2010));
            marshaller.marshal(student, System.out);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
    // 测试Xml文件转化为Java文件
    @Test
    public void testXml2Java() {
        String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>"
                + "<student>"
                    + "<age>20</age>"
                    + "<classroom>"
                        + "<grade>2010</grade>"
                        + "<id>10</id>"
                        + "<name>10级生命科学与工程</name>"
                    + "</classroom>"

        try {
            JAXBContext ctx = JAXBContext.newInstance(Student.class);
            // 用于Xml文件转化为Java文件的类
            Unmarshaller um = ctx.createUnmarshaller();
            Student student = (Student) um.unmarshal(new StringReader(xml));
            System.out.println(student.getName() + ","
                    + student.getClassroom().getName());
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
