## Backport of #23886
Cherry-pick of #23886 (squash commit `72d13bd13fb`) onto `camel-4.14.x`.
- **Original PR:** apache/camel#23886 โ CAMEL-23630: add
HeaderFilterStrategy to camel-dapr
- **Original author:** @oscerd
- **Approved by:** @davsclaus
- **Target branch:** `camel-4.14.x` (4.14.8-SNAPSHOT)
### What this backports
Adds `DaprHeaderFilterStrategy` (exposed via `DaprComponent` /
`DaprEndpoint` as the standard `headerFilterStrategy` option) and stops the
`dapr-pubsub` consumer from copying the inbound CloudEvent's `pubsubName` /
`topic` into the `CamelDaprPubSubName` / `CamelDaprTopic` headers. Those two
constants are producer-direction routing headers that
`DaprConfigurationOptionsProxy` reads back and prefers over the
endpoint-configured destination, so a `from(dapr-pubsub).to(dapr-pubsub)` route
incorrectly carried the inbound destination into the producer hop. The
remaining CloudEvent metadata headers are unchanged.
### Backport notes
- **Upgrade-guide entry omitted by design.** The original PR added a note to
`camel-4x-upgrade-guide-4_21.adoc`, which does not exist on `camel-4.14.x`. Per
project policy, upgrade-guide entries live on `main`; the matching
`camel-4x-upgrade-guide-4_14.adoc` entry on `main` is handled in the doc-sync
PR #23891.
- **Conflicts resolved** (this branch diverges more from `main` than 4.18.x
did):
- `DaprEndpoint.java`: kept the 4.14.x `@UriEndpoint` annotation
formatting and added `implements HeaderFilterStrategyAware`; the rest of the
endpoint change (imports, the `headerFilterStrategy` `@UriParam`,
getter/setter) applied cleanly.
- The generated files (`DaprComponentConfigurer`,
`DaprEndpointConfigurer`, `DaprEndpointUriFactory`, component `dapr.json`, and
the catalog mirror) were **regenerated** from source on this branch rather than
taking the 4.21 versions, so they match 4.14.x codegen.
- **Validated locally:** `mvn -pl components/camel-dapr clean install` on a
`camel-4.14.x` worktree โ BUILD SUCCESS, 28 tests pass (incl.
`DaprPubSubConsumerTest`), no regenerated-file drift.
