Spring OXM - 测试 JAXB2
使用 marshaller 和 unmarshaller 对象创建一个主类 OXMApplication.java。 此类的目标是使用 marshaller 对象将 student 对象编组为 student.xml，然后使用 unmarshaller 对象将 student.xml 解组为 student 对象。
示例
OXMApplication.java
实例
package com.tutorialspoint.oxm;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.oxm.Marshaller;
import org.springframework.oxm.Unmarshaller;
import org.springframework.oxm.XmlMappingException;
import com.tutorialspoint.oxm.model.Student;
public class OXMApplication {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationcontext.xml");
Marshaller marshaller = (Marshaller)context.getBean("jaxbMarshaller");
Unmarshaller unmarshaller = (Unmarshaller)context.getBean("jaxbMarshaller");
// create student object
Student student = new Student();
student.setAge(14);
student.setName("Soniya");
try {
marshaller.marshal(student, new StreamResult(new FileWriter("student.xml")));
System.out.println("Student marshalled successfully.");
FileInputStream is = new FileInputStream("student.xml");
Student student1 = (Student)unmarshaller.unmarshal(new StreamSource(is));
System.out.println("Age: " + student1.getAge() + ", Name: " + student1.getName());
} catch(IOException | XmlMappingException ex) {
ex.printStackTrace();
}
}
}
输出
在 Eclipse 中右键单击文件的内容区域，然后选择 Run as java application 并验证输出。
