Service
Since Camel 2.22
Only consumer is supported
Options
The Service component supports 4 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
bridgeErrorHandler (consumer) |
Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. |
false |
boolean |
autowiredEnabled (advanced) |
Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. |
true |
boolean |
service (advanced) |
Inject the service to use. |
ServiceRegistry |
|
serviceSelector (advanced) |
Inject the service selector used to lookup the ServiceRegistry to use. |

<dependency>
