WebService(2)-XML系列之Java和Xml之间相互转换

源码下载：链接: http://pan.baidu.com/s/1ntL1a7R 密码: rwp1

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>"
					+ "<id>1001</id>"
					+ "<name>赵栗婧</name>"
				+ "</student>";
		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();
		}

	}
