Raymond created CAMEL-23652:
-------------------------------
Summary: [kamelet] Bean is not registered
Key: CAMEL-23652
URL: https://issues.apache.org/jira/browse/CAMEL-23652
Project: Camel
Issue Type: Bug
Components: camel-kamelet
Affects Versions: 4.20.0
Reporter: Raymond
I like to use the following Kamelet:
[https://github.com/apache/camel-kamelets/blob/main/kamelets/counter-source.kamelet.yaml]
I slightly altered the Kamelet route to this:
{code:java}
template:
beans:
- name: counter
type: java.util.concurrent.atomic.AtomicInteger
constructors:
"0": "{{start}}"
from:
uri: timer:counter
parameters:
period: "{{period}}"
repeatCount: "{{?numbers}}"
steps:
- bean:
ref: "{{counter}}"
method: getAndIncrement
- setHeader:
name: "Content-Type"
constant: "text/plain"
- to: "{{out}}" {code}
However when I call this the bean is not recognized, and a property is
expected. This is the error I see:
{code:java}
Failed to create route:
69b3f52efbdb4c0011000147-7cee7a5b-d34c-450e-a8d0-02972b6ad07c at: >>>
Bean[ref:{{counter}} method:getAndIncrement] <<< in route:
Route(69b3f52efbdb4c0011000147-7cee7a5b-d34c-450e-a8d0-02972... because:
Property with key [counter] not found in properties from text: {{counter}}"
{code}
I loaded the Kamelets like this:
{code:java}
public void setRouteTemplates() {
List<String> resourceNames = getKamelets();
RoutesLoader routesLoader = PluginHelper.getRoutesLoader(context);
for (String resourceName : resourceNames) {
Resource resource =
ResourceHelper.resolveResource(context,"classpath:kamelets/" + resourceName);
try {
routesLoader.loadRoutes(resource);
} catch (Exception e) {
log.warn("Could not load Kamelet: {}. Reason: {}", resourceName,
e.getMessage());
}
}
} {code}
I have around 200 Kamelets, and they load and function correctly. The only
thing that have issues is with the dynamically registered beans that locally
scoped with the Kamelet. Registering the bean programmatically, and then
referencing it (both hardcoded or with a property) works fine.
Is this because they are loaded throught the routesLoader (both the Kamelet, as
the templatedRoute)? Is this bug or I am missing something?
