如何使用JAXB序列化和反序列化对象？

您可以执行以下操作。

注意：

• 不需要利用JAXBSource将数据具体化为XML。
• 它在对象模型上不需要任何注释。

com.home.Student

package com.home;public class Student {    private String name;    private Status status;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Status getStatus() {        return status;    }    public void setStatus(Status status) {        this.status = status;    }}

com.home.Status

package com.home;public enum Status {    FULL_TIME("F"),    PART_TIME("P");    private final String pre;    Status(String pre) {        this.pre = pre;    }    public String getCode() {        return pre;    }}

普通学校学生

package com.school;public class Student {    private String name;    private Status status;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Status getStatus() {        return status;    }    public void setStatus(Status status) {        this.status = status;    }}

com.school.Status

package com.school;public enum Status {    FULL_TIME("F"),    PART_TIME("P");    private final String pre;    Status(String pre) {        this.pre = pre;    }    public String getCode() {        return pre;    }}

com.example.Demo;

package com.example;import javax.xml.bind.JAXBContext;import javax.xml.bind.JAXBElement;import javax.xml.bind.Unmarshaller;import javax.xml.bind.util.JAXBSource;import javax.xml.namespace.QName;public class Demo {    public static void main(String[] args) throws Exception {        com.home.Student studentA = new com.home.Student();        studentA.setName("Jane Doe");        studentA.setStatus(com.home.Status.FULL_TIME);        JAXBContext contextA = JAXBContext.newInstance(com.home.Student.class);        JAXBElement<com.home.Student> jaxbElementA = new JAXBElement(new QName("student"), com.home.Student.class, studentA);        JAXBSource sourceA = new JAXBSource(contextA, jaxbElementA);        JAXBContext contextB = JAXBContext.newInstance(com.school.Student.class);        Unmarshaller unmarshallerB = contextB.createUnmarshaller();        JAXBElement<com.school.Student> jaxbElementB = unmarshallerB.unmarshal(sourceA, com.school.Student.class);        com.school.Student studentB = jaxbElementB.getValue();        System.out.println(studentB.getName());        System.out.println(studentB.getStatus().getCode());    }}
