JinyuChen97 opened a new pull request, #25097:
URL: https://github.com/apache/camel/pull/25097
## Summary
Fix regression where camel export fails with MongoTimeoutException /
AllNodesFailedException for kamelets using #class: Component beans (e.g.
mongodb-sink, cassandra-sink) because the real component is instantiated
instead of being replaced with StubComponent.
The root cause: commit 5d4c6cbf0746 (CAMEL-22667) added an outer else {
accept = true; } branch in KameletMainInjector.acceptComponent(). However, this
branch also impact when stubPattern is "*" (used by camel export), overriding
accept=false back to true for components not in ACCEPTED_STUB_NAMES, causing
real components like MongoDbComponent / CassandraComponent to be loaded and
attempt connections to non-existent instances.
## Changes
KameletMainInjector.java — Removed the outer else { accept = true; } branch
in acceptComponent(). When stubPattern is "*", accept now remains as returned
by accept(type): true for ACCEPTED_STUB_NAMES components, false for everything
else, which can fix the loading non existed instance behavior with camel export.
## Test plan
- New KameletMainInjectorTest verifies that non-whitelisted components are
stubbed with stubPattern=* and "component:*", whitelisted components are
allowed through, and non-Component classes pass unchanged
