package com.mkyong.core; 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; public String getName() { return name; } @XmlElement public void setName(String name) { this.name = name; } public int getAge() { return age; } @XmlElement public void setAge(int age) { this.age = age; } public int getId() { return id; } @XmlAttribute public void setId(int id) { this.id = id; } }
package com.mkyong.core; import java.io.File; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Marshaller; public class JAXBExample { 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(); } } }
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <customer id="100"> <age>29</age> <name>mkyong</name> </customer>
第一步:把数据库表映射为xml
<?xml version="1.0" encoding="UTF-8"?> <User u_id="1" u_name="moto" u_email="[email protected]" u_mood="今天放假了" u_state="online" u_mobile="12345678901" u_hometown="山西" u_job="IT软件工程师" u_avatar="w34353453543r53" />第二步:使用 trang.jar转化为xsd文件。在命令行执行:
java -jar D:\lib\trang.jar user.xml user.xsd下面,是生成的User.java。
