Bright Zheng created CXF-5509:
---------------------------------
Summary: NullPointerException if class with generic-array
parameters is set to rootClassNames
Key: CXF-5509
URL: https://issues.apache.org/jira/browse/CXF-5509
Project: CXF
Issue Type: Bug
Components: Aegis Databinding
Affects Versions: 2.7.8
Environment: RHEL6.3 (64b), JDK1.6, Spring 3.0.6, CXF 2.7.8
Reporter: Bright Zheng
I want to expose a set of classes by setting the aegisContext:
{code:xml}
<bean id="aegisContext" class="org.apache.cxf.aegis.AegisContext"
scope="prototype">
<property name="writeXsiTypes" value="true"/>
<property name="rootClassNames">
<ref bean="bindingList"/>
</property>
</bean>
{/code}
One of the class in the list is as a response pojo which has generic-array
field like:
{code:java}
public class Subject<T extends Score>{
...
private T[] score;
//and getter/setter also
...
{code}
During the deployment phase, while debugging with the CXF code, I found that
below codes in TypeUtil.java under cxf-rt-databinding-aegis-2.7.8.jar will case
issue:
{code:java}
public static Class<?> getTypeRelatedClass(Type type) {
Class<?> directClass = getTypeClass(type, false);
if (directClass != null) {
return directClass;
}
if (type instanceof ParameterizedType) {
ParameterizedType pType = (ParameterizedType) type;
return getTypeRelatedClass(pType.getRawType());
}
if (type instanceof GenericArrayType) {
GenericArrayType gat = (GenericArrayType) type;
Type compType = gat.getGenericComponentType();
Class<?> arrayBaseType = getTypeRelatedClass(compType);
// believe it or not, this seems to be the only way to get the
// Class object for an array of primitive type.
Object instance = Array.newInstance(arrayBaseType, 0);
return instance.getClass();
}
return null;
}
{code}
{color:red}
Note: the arrayBaseType will be always null while initializing that class os it
will cause the next line of code NPE!!
{color}
Did I miss anything for this kind of class mapping while using aegis?
