How to convert java object to xml using JAXB to get the following xml:
1.0

There are many answers regarding how to get XML. I have gone through all those. But my question is how to get the XML as what I have shown. It contains a self-closing tag which even contains attributes.
I am using Eclipse IDE. Please suggest a method.
This is my case class:
import auth.Res.Meta;
@XmlRootElement (name="Case")
public class Test {
private Meta mt;
private String version;
private String code;
@XmlRootElement
public class Meta {
@XmlAttribute
private String uc;
@XmlAttribute
private String pip;
public String getUc() {
return uc;
}
public void setUc(String uc) {
this.uc = uc;
}
public String getPip() {
return pip;
}
public void setPip(String pip) {
this.pip = pip;
}
}
public Meta getMt() {
return mt;
}
public void setMt(Meta mt) {
this.mt = mt;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
}
Solution:
I solved it by creating seperate class for Meta as suggested by LazerBanana in the first answer.
解决方案
This is how your Meta class should look like.
public class Meta {
private String uc;
private String pip;
private String lot;
public String getUc() {
return uc;
}
@XmlAttribute
public void setUc(String uc) {
this.uc = uc;
}
public String getPip() {
return pip;
}
@XmlAttribute
public void setPip(String pip) {
this.pip = pip;
}
public String getLot() {
return lot;
}
@XmlAttribute
public void setLot(String lot) {
this.lot = lot;
}
}
this is your Case class which is the root element
@XmlRootElement
public class Case {
private int version;
private String code;
private String id;
private Meta meta;
public int getVersion() {
return version;
}
@XmlElement
public void setVersion(int version) {
this.version = version;
}
public String getCode() {
return code;
}
@XmlElement
public void setCode(String code) {
this.code = code;
}
public String getId() {
return id;
}
@XmlElement
public void setId(String id) {
this.id = id;
}
public Meta getMeta() {
return meta;
}
@XmlElement
public void setMeta(Meta meta) {
this.meta = meta;
}
}
And this is the marshaling bit to the console and to the file it you want.
public class Main {
public static void main(String... args) {
Case fcase = new Case();
Meta meta = new Meta();
meta.setLot("asd");
meta.setPip("sdafa");
meta.setUc("asgd4");
fcase.setMeta(meta);
fcase.setVersion(1);
fcase.setId("sah34");
fcase.setCode("code34");
try {
// File file = new File("C:\\file.xml");
JAXBContext jaxbContext = JAXBContext.newInstance(Case.class, Meta.class);
Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
// output pretty printed
jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
// jaxbMarshaller.marshal(fcase, file);
jaxbMarshaller.marshal(fcase, System.out);
} catch (JAXBException e) {
e.printStackTrace();
}
}
}
Output:
code34

Next time please try to do more research i am not an expert and I just googled it.
