Croway opened a new pull request, #1777:
URL: https://github.com/apache/camel-spring-boot/pull/1777
## Summary
- Fix `BeanCurrentlyInCreationException` circular dependency between
`CamelContext` and all generated auto-configuration classes (Component,
Language, DataFormat, Rest)
- Fix `PlaceholderResolutionException` for `local.server.port` in
platform-http tests exposed by Spring Framework 7.0.7
## Root cause
The `@AutoConfiguration` migration (commit 136b6c53c47) combined with Spring
Boot 4.0.6 (Spring Framework 7.0.7) triggers `BeanCurrentlyInCreationException`
during `CamelContext` initialization. During `camelContext.build()`, Camel's
`CustomizersLifecycleStrategy` calls
`registry.findByType(ComponentCustomizer.class)` which forces Spring to
instantiate auto-configuration classes that require `CamelContext` in their
constructor — creating a circular dependency.
## Changes
**Code generator** (`SpringBootAutoConfigurationMojo`):
- **Component auto-configs**: Remove `CamelContext` from constructor. Use
`target.getCamelContext()` in the customizer body — the Component already knows
its context when the customizer is invoked
- **Language auto-configs**: Remove `CamelContext` from constructor. Use
`instanceof CamelContextAware` pattern matching — not all Language
implementations extend `LanguageSupport` (e.g. `ExchangePropertyLanguage`)
- **DataFormat/Rest auto-configs**: Use `ObjectProvider<CamelContext>` for
deferred resolution — these are not resolved during `camelContext.build()`
**Hand-written auto-configs**:
- Fix wrong `afterName` package in `SpringBootPlatformHttpAutoConfiguration`
(`servlet.springboot` → `platform.http.springboot`)
- Use `ObjectProvider<CamelContext>` in
`SpringBootPlatformHttpAutoConfiguration.platformHttpEngineRequestMapping()`
**Platform-HTTP tests** (20 files):
- Replace `@LocalServerPort` with
`Environment.getRequiredProperty("local.server.port", Integer.class)` in
`@BeforeEach`. The `local.server.port` property is set during `finishRefresh()`
but beans registered via `@SpringBootTest(classes=...)` are created during
`finishBeanFactoryInitialization()` — before the server port is assigned.
Spring Framework 7.0.7 changed pre-instantiation timing, exposing this latent
issue.
## Test plan
- [x] `mvn test -pl components-starter/camel-platform-http-starter` — 96
passed, 0 failed, 2 skipped (WireMock @Disabled)
- [x] `mvn test -pl core/camel-spring-boot
-Dtest=ThreadPoolConfigurationTest` — passed
- [ ] Full CI build validation
