CamelContext Auto Configuration

The CamelContext is autoconfigured when running Camel with either Camel Main, Camel Spring Boot, Camel Quarkus.

Camel Autoconfiguration

Under these runtimes then the autoconfiguration is performed by shared code from the camel-main JAR to ensure the configuration is similar on these runtimes.

The autoconfiguration is executed in several steps:

Configure CamelContext (and more such as components) from properties from external sources like application.properties|yaml
Configure optional services that have been registered in the Registry

Autoconfiguration of Properties

This is used for configuring the standard set of more than 100 options which are listed in the Camel Main Options table at Camel Main.

	When using Camel on Spring Boot, then these options are prefixed with `camel.springboot`, and not `camel.main`.

Autoconfiguration of Optional Services

After configuring the standard options, then Camel will look in the Registry for custom services to be used. For example, to plug in a custom UnitOfWorkFactory.

The services can be anything that can be plugged into Camel (typically services that implement an SPI interface org.apache.camel.spi).

The following SPI services can only a single instance (singleton) be in the Registry.

SPI	Description
`AsyncProcessorAwaitManager`	To use a custom async processor await manager
`BacklogTracer`	To use a custom backlog tracer
`ClassResolver`	To use a custom class resolver. This is only necessary if you run Camel on a special application server to deal with classloading.
`Debugger`	To use a custom debugger
`EventFactory`	To use a custom event notifier factory
`ExchangeFactory`	To use a custom exchange factory
`ExecutorServiceManager`	To use a custom thread pool manager
`FactoryFinderResolver`	To use a custom factory finder resolver. This is only necessary if you run Camel on a special application server to deal with classloading.
`HealthCheckRegistry`	To use a custom health check registry
`InflightRepository`	To use a custom in flight repository
`ManagementObjectNameStrategy`	To use a custom JMX MBean object naming
`ManagementStrategy`	To use a custom JMX management strategy
`MessageHistoryFactory`	To use a custom factory for message history
`ModelJAXBContextFactory`	To use a custom `JAXBContext` factory (only needed if you run Camel on a special application server to deal with JAXB classloading)
`NodeIdFactory`	To use a custom factory for creating auto generated node ids
`ProcessorFactory`	To use a custom factory for creating EIP processors
`PropertiesComponent`	To use a custom properties component
`ReactiveExecutor`	To use a custom reactive engine in the Camel routing engine
`RouteController`	To use a custom route controller
`RuntimeEndpointRegistry`	To use a custom runtime endpoint registry
`ShutdownStrategy`	To use a custom shutdown strategy
`StartupStepRecorder`	To use a custom startup recorder
`ThreadPoolFactory`	To use a custom thread pool factory
`UnitOfWorkFactory`	To use a custom unit of work factory
`UuidGenerator`	To use a custom uuid generator

For the following SPI services, there can be multiple (one or more) implementations in the Registry.

SPIs	Description
`CamelClusterService`	Adds all the custom camel-cluster services
`EndpointStrategy`	Adds all the custom endpoint strategies
`EventNotifier`	Adds all the custom event notifiers
