@XmlType
@XmlAccessorType(XmlAccessType.FIELD) // here I need this access
public class User implements Serializable
{
// ...
@XmlTransient
private Set<Values> values;
// ...
@XmlElement
private Set<History> getXmlHistory()
{
return new CustomSet<Values, History>(Values);
}
private void setXmlHistory(final Set<History> aHistory)
{
this.values = new HashSet<Values>();
}
}
When I am create User object in Java code and after create XML, then all normally.
But when I try to get User-object from XML, then field values
always null
. So setter not working here. May be setter needs some annotation too?
XML looks like
<user>
...
<xmlHistory>
// ... record 1
</xmlHistory>
<xmlHistory>
// ... record 2
</xmlHistory>
</user>
I do not believe that this is a JAXB problem, as the following model will work:
package forum10617267;
import java.io.Serializable;
import java.util.*;
import javax.xml.bind.annotation.*;
@XmlType
@XmlAccessorType(XmlAccessType.FIELD) // here I need this access
public class User implements Serializable {
@XmlTransient
private Set<History> history = new HashSet<History>();
@XmlElement
private Set<History> getXmlHistory() {
return history;
}
private void setXmlHistory(final Set<History> aHistory) {
this.history = aHistory;
}
}
The problem you are seeing is a result of the logic you have in your get/set methods. Since your values
field is not initialized, I am not sure how CustomSet
would be able to update it.
package forum10617267;
import java.io.Serializable;
import java.util.*;
import javax.xml.bind.annotation.*;
@XmlType
@XmlAccessorType(XmlAccessType.FIELD) // here I need this access
public class User implements Serializable {
@XmlTransient
private Set<Values> values;
@XmlElement
private Set<History> getXmlHistory() {
return new CustomSet<Values, History>(values);
}
private void setXmlHistory(final Set<History> aHistory) {
this.values = new HashSet<Values>();
}
}
I believe that @XmlAccessorType(XmlAccessType.FIELD)
in combination with your @XmlTransient
is the source of the problem. Have you tried without the transient annotation?
