Hi,
using the following auto-generated classes (Class1, Class2) causes an
AmbiguousMethodCallException in a unit test, although the mentioned methods are
not ambiguous. Class1 looks like this:
@javax.annotation.Generated…
public class Class1 {
@JsonProperty("data")
private Class2 data = null;
public Class1 data(Class2 data) {
this.data = data;
return this;
}
public Class2 getData() {
return data;
}
public void setData(Class2 data) {
this.data = data;
}
}
I did not find a way to get rid of the auto-generated method “public Class1
data(Class2 data)”, so I checked why this exception is thrown in Camel.
org.apache.camel.component.bean.AmbiguousMethodCallException: Ambiguous method
invocations possible:
public Class2 Class1.getData()
public Class1 Class1.data(Class2)
Obviously these two methods have different return types and different
parameters, so there should not be an ambiguous method invocation possible here.
I think the problem is in class org.apache.camel.component.bean.BeanInfo in the
following method:
private List<MethodInfo> getOperations(String methodName) {
// do not use qualifier for name
if (methodName.contains("(")) {
methodName = StringHelper.before(methodName, "(");
}
List<MethodInfo> answer = operations.get(methodName);
if (answer != null) {
return answer;
}
// now try all getters to see if any of those matched the methodName
for (Method method : methodMap.keySet()) {
if (isGetter(method)) {
String shorthandMethodName = getGetterShorthandName(method);
// if the two names matches then see if we can find it using
that name
if (methodName != null &&
methodName.equals(shorthandMethodName)) {
return operations.get(method.getName());
}
}
}
return null;
}
Here, the method “data” is mapped to the (already known) method “getData”
without considering return values or parameters of these methods (only the name
is compared).

Manuel
