IllegalAnnotationException on Collection properties, Getter must return
"Collection", Setter must take "List" as parameter
--------------------------------------------------------------------------------------------------------------------------
Key: CXF-2168
URL: https://issues.apache.org/jira/browse/CXF-2168
Project: CXF
Issue Type: Bug
Components: JAXB Databinding
Environment: jax-rs
Reporter: VividApp On Software
Priority: Critical
Problem is with jaxb in relation to jax-rs.
This problem is excruciatingly annoying and has resulted in days of wasted
time, almost to the point of giving up!!
I am marking this as Critical, as I think it will drive people away from using
CXF jax-rs if they encounter this problem.
Getting some very strange behaviour with Collection properties if I do not do
the following.
- The Getter must a type of "Collection"
- The Setter parameter must be a "List".
If both Getter and Setter are consistent and both return either a Collection or
a List, an IllegalAnnotationException occurs (See Debug output below).
ie. One must return a Collection, and the other must take a List.
I get this if I annotate with @XmlElementRefs and also with @XmlAnyElement
(coupled with @XmlSeeAlso)
I don't think this is a problem with the jaxb-api, as I also tried it with jaxb
2.0
I have included my Maven dependency at the bottom.
############################
My code is as follows:
@XmlRootElement(name = "data")
// @XmlSeeAlso({Echo.class, Basicdetails.class, UrlDescriptor.class})
public class Data {
// @XmlAnyElement(lax = true)
@XmlElementRefs({
@XmlElementRef(name = "basicdetails", type = Basicdetails.class),
@XmlElementRef(name = "urldescriptor", type = UrlDescriptor.class),
@XmlElementRef(name = "echo", type = Echo.class)
})
private Collection<Record> records;
public Data() {
}
public Data(final Record record) {
addRecord(record);
}
public Collection<Record> getRecords() {
return records;
}
/**
* THIS MUST TAKE A LIST, EXCEPTIONS OTHERWISE, EVEN THOUGH GETTER IS
RETURNING "Collection"
*/
public void setRecords(final List<Record> records) {
this.records = records;
}
public void addRecord(final Record record) {
if (this.records == null) {
setRecords(new ArrayList<Record>());
}
getRecords().add(record);
}
}
