How do I change the name of an XmlRootElement in JAXB that is not an object?
I have the following objects
Film
@Entity
@Table(name="film")
@XmlRootElement(name = "film")
public class Film implements Serializable {
@Id
@Column(name="id")
private String fbId;
@Column(name="title")
private String title;
@ManyToMany
@JoinTable(
name="direction",
joinColumns={@JoinColumn(name="film", referencedColumnName="id")},
inverseJoinColumns={@JoinColumn(name="person", referencedColumnName="id")})
private Collection<Person> directors;
@OneToMany(cascade={CascadeType.ALL}, mappedBy="film")
@MapKey(name="character")
private Map<String, Performance> performances;
//GETTERS
@XmlAttribute(name = "fbId")
public String getFreebaseId() {
return this.fbId;
}
@XmlElementRefs({
@XmlElementRef(name="director", type=Person.class)
})
public Collection<Person> getDirectors() {
return this.directors;
}
@XmlAnyElement(lax=true)
public Collection<Performance> getPerformances() {
ArrayList performancesArray = new ArrayList<Performance>();
for (Map.Entry<String, Performance> entry : this.performances.entrySet()) {
Performance value = entry.getValue();
performancesArray.add(value);
}
return performancesArray;
}
}
Person
@Entity
@Table(name="person")
public class Person implements Serializable {
@Id
@Column(name="id")
private String fbId;
@Column(name="first_name")
private String firstName;
@Column(name="last_name")
private String lastName;
@OneToMany(cascade={CascadeType.ALL}, mappedBy="actor")
@XmlTransient
private Collection<Performance> performances;
//GETTERS
@XmlAttribute(name = "fbId")
public String getFreebaseId() {
return this.fbId;
}
@XmlElement(name = "firstName")
public String getFirstName() {
return this.firstName;
}
@XmlElement(name = "lastName")
public String getLastName() {
return this.lastName;
}
@XmlTransient
public Collection<Performance> getPerformances() {
return this.performances;
}
}
Each film has one (or many) directors and performances who are "Faces". I don’t need a class for directors, but I do it for speaking because they have more information.
Performance
@Entity
@Table(name="performance")
@XmlRootElement(name = "performace")
public class Performance implements Serializable {
@Id
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="film")
private Film film;
@Id
@Column(name="film_character")
private String character;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="actor")
private Person actor;
//TO STRING
public String toString() {
return this.actor.toString() + " - " + this.character;
}
//GETTERS
@XmlTransient
public Film getFilm() {
return this.film;
}
@XmlElementRefs({
@XmlElementRef(name = "firstName", type = Person.class),
@XmlElementRef(name = "lastName", type = Person.class)
})
public Person getActor() {
return this.actor;
}
@XmlElement(name = "character")
public String getCharacter() {
return this.character;
}
}
When I run this through JAXB I get this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<film fbId="1">
<description>Nice film</description>
<person fbId="1">
<firstName>Quentin</firstName>
<lastName>Tarantino</lastName>
</person>
<performace>
<person fbId="4">
<firstName>Steve</firstName>
<lastName>Buscemi</lastName>
</person>
<character>Billy</character>
</performace>
<performace>
<person fbId="2">
<firstName>Jhon</firstName>
<lastName>Travolta</lastName>
</person>
<character>Vincent</character>
</performace>
<performace>
<person fbId="3">
<firstName>Samuel</firstName>
<lastName>L Jackson</lastName>
</person>
<character>Jules</character>
</performace>
<performace>
<person fbId="1">
<firstName>Quentin</firstName>
<lastName>Tarantino</lastName>
</person>
<character>Jimmie</character>
</performace>
<title>Pulp Fiction</title>
</film>
Is there a way to change the name "person"? To get something like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<film fbId="1">
<description>Nice film</description>
<director fbId="1">
<firstName>Quentin</firstName>
<lastName>Tarantino</lastName>
</director>
<performace fbId="4">
<firstName>Steve</firstName>
<lastName>Buscemi</lastName>
<character>Billy</character>
</performace>
<performace fbId="2">
<firstName>Jhon</firstName>
<lastName>Travolta</lastName>
<character>Vincent</character>
</performace>
<performace fbId="3">
<firstName>Samuel</firstName>
<lastName>L Jackson</lastName>
<character>Jules</character>
</performace>
<performace fbId="1">
<firstName>Quentin</firstName>
<lastName>Tarantino</lastName>
<character>Jimmie</character>
</performace>
<title>Pulp Fiction</title>
</film>

Parameters:
- Make
Director
extendsPerson
with your@XmlRootElement
- Use
JAXBElement<? extends Person>
insteadPerson
The problem is that @ XmlElementRef.name doesn't work for @XmlRootElement
, read here :
If type () is JAXBElement.class, then namespace () and name () point to a factory with XmlElementDecl. The XML element name is the name of the element from the factory annotation XmlElementDecl method, or if an element from its replacement group (of which it is a head element) has been replaced in the XML document, then the element name from the XmlElementDecl on the replaced element.
If type () is not JAXBElement.class, then the XML element name is the XML element name, statically associated with the type using the type XmlRootElement annotation. If the type is not annotated with XmlElementDecl, then this is an error.
If type () is not JAXBElement.class then this value must be "".
By the way,
@XmlElementRefs({
@XmlElementRef(name = "firstName", type = Person.class),
@XmlElementRef(name = "lastName", type = Person.class)
})
doesn't suit me. @XmlElementRef
should not display properties of the target class.
