JAXB 是否存在内存利用率问题

JAXB（Java Architecture for XML Binding）是一种Java技术，用于将Java对象与XML文档进行相互转换。在使用JAXB时，一些开发者关心它是否存在内存利用率问题。本文将探讨JAXB的内存利用率问题，并通过案例代码进行验证。

java
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Person {
    private String name;
    private int age;
    private String address;
    @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;
    }
    @XmlElement
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
}

java
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
public class Main {
    public static void main(String[] args) {
        Person person = new Person();
        person.setName("张三");
        person.setAge(25);
        person.setAddress("北京市");
        try {
            JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);
            Marshaller marshaller = jaxbContext.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshaller.marshal(person, System.out);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}
