-----------------------------------
Summary: Parameterized Classes should be automatically added to
JAXBContext
Key: CXF-4799
URL: https://issues.apache.org/jira/browse/CXF-4799
Project: CXF
Issue Type: Improvement
Components: JAXB Databinding
Affects Versions: 2.7.2
Reporter: Sambit Dikshit
We are using a payload type which is a parameterized generic. For example,
ServiceResponse<T> {
T payload;
public T getPayload() {
return T
}
public void setPayload(T t){
this.payload = t;
}
We are using this as a payload wrapper for JAXRS services. The payload can be
any type at runtime. Unless we set the extraClass, the JAXBContext created in
AbstractJAXBProvider is not picking up the actual parameter types. I was
thinking of extending to add to existing jaxb context map, i could not since
its a private scoped hashmap. This should be automatically handled in
AbstractJAXBProvider class. Following check can be made and added for actual
type.
ParameterizedType paramType = (genericType instanceof ParameterizedType) ?
(ParameterizedType) genericType: null;
if (paramType.getActualTypeArguments().length > 0) {
// Fetch the actual type at index 0
actualWrapperParamType = InjectionUtils.getType(
paramType.getActualTypeArguments(), 0);
Class<?> actualWrapperClass =
InjectionUtils.getActualType(actualWrapperParamType);
This actual class type check can be done inside getJAXBContext. This will do
automatic deep check and setting into JAXB context only for custom payload
types.
Or else expose the jaxb context map to be accessible when extend
AbstractJAXBprovider or JAXBElementProvider.
