WebService(2)-XML系列之Java和Xml之间相互转换

源代码下载：链接: http://pan.baidu.com/s/1ntL1a7R password: rwp1

本文主要讲述：使用jaxb完毕对象和xml之间的转换

TestJava2xml.java例如以下所看到的：

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 {

	// 測试：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project", 2010));
			marshaller.marshal(student, System.out);

		} catch (JAXBException e) {
			e.printStackTrace();
		}
	}

	// 測试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project</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();
		}

	}
