JAXB java对象与xml转化

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customer {
	String name;
	int age;
	int id;

	@XmlElement
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	@XmlElement
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
	@XmlAttribute
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	
	@Override
	public String toString() {
		return "Customer [id=" + id + ",name=" + name + ",age=" + age + "]";
	}

	
	
}

生成对象到xml

import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

//Marshaller
public class Object2XmlDemo {
	public static void main(String[] args) {

		Customer customer = new Customer();
		customer.setId(100);
		customer.setName("mkyong");
		customer.setAge(29);
		try {
			File file = new File("C:\\file.xml");
			JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
			Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
			// output pretty printed
			jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
			jaxbMarshaller.marshal(customer, file);
			jaxbMarshaller.marshal(customer, System.out);
		} catch (JAXBException e) {
			e.printStackTrace();
		}
	}
}

读取xml到对象

import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

//Unmarshaller
public class Xml2ObjectDemo {
	public static void main(String[] args) {
		try {
			File file = new File("C:\\file.xml");
			JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
			Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
			Customer customer = (Customer) jaxbUnmarshaller.unmarshal(file);
			System.out.println(customer);
		} catch (JAXBException e) {
			e.printStackTrace();
		}
	}
}
