Marco Bungart updated CAMEL-19234:
----------------------------------
Description:
Currently, when we look up a mandatory bean which type we know, we perform the
lookup with the bean's name and convert it to the requested type:
{code:java}
public static <T> T mandatoryLookupAndConvert(CamelContext context, String
name, Class<T> beanType) {
Object value = lookup(context, name);
if (value == null){
throw new NoSuchBeanException(name, beanType.getName());
}
return convertTo(context, beanType, value);
}
{code}
Source:
[https://github.com/apache/camel/blob/main/core/camel-support/src/main/java/org/apache/camel/support/CamelContextHelper.java#L245]
This leads to problem with the current implementation of
[https://github.com/apache/camel-quarkus/issues/4725,] where we introduced
automatic registration of beans annotated with {{@Identifier}} . When several
beans with the same {{@Identifier("<name>")}} but different types are present.
We think we can prevent this problem when we modify above method to do a
{{lookup(...)}} with the type information, and only do the {{lookup(...)}}
without type information if the {{{}lookup(...){}}}with type information
yielded no result.
