Maven users will need to add the following dependency to their pom.xml for in order to use this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring-boot</artifactId>
    <version>${camel.version}</version> <!-- use the same version as your Camel core version -->
</dependency>

...

Apache Camel ships a Spring Boot Starter module that allows you to develop Spring Boot applications using starter'sstarters. There is a sample application in the source code also.

...

The most important piece of functionality provided by the Camel auto-configuration is CamelContext instance. Camel auto-configuration creates a SpringCamelContext for you and takes care of the proper initialization and shutdown of that context. The created Camel context is also registered in the Spring application context (under camelContext bean name), so you can access it just as  any other Spring bean.

...

Camel auto-configuration collects all the RouteBuilder instances from the Spring context and automatically injects them into the provided CamelContext. It That means that creating new Camel route with the Spring Boot starter is as simple as adding the @Component annotated class into to your classpath:

@Component
public class MyRouter extends RouteBuilder {

  @Override
  public void configure() throws Exception {
    from("jms:invoices").to("file:/invoices");
  }

}

...

Camel auto-configuration provides a pre-configured ConsumerTemplate and ProducerTemplate instances. You can simply inject them into your Spring-managed beans:

@Component
public class InvoiceProcessor {

  @Autowired
  private ProducerTemplate producerTemplate;

  @Autowired
  private ConsumerTemplate consumerTemplate;
  public void processNextInvoice() {
    Invoice invoice = consumerTemplate.receiveBody("jms:invoices", Invoice.class);
    ...
    producerTemplate.sendBody("netty-http:http://invoicing.com/received/" + invoice.id());
  }

}

By default consumer templates and producer templates comes come with the endpoint cache sizes equal set to 1000. You can change those values via the following Spring properties:

...

Auto-configured TypeConverter

Camel auto-configuration registers registers a TypeConverter instance named typeConverter in the Spring context.

...

Spring comes with the powerful type conversion API. Spring API happens not to be much different from very similar to the Camel type converter API. As those APIs are so similar, Camel Spring Boot automatically registers a bridge converter (SpringTypeConverter) that delegates to the Spring conversion API. It basically That means that out-of-the-box Camel will treat Spring Converters as like Camel ones. With this approach you can enjoy both Camel and Spring converters accessed via Camel TypeConverter API:

The easiest way to create a Camel-aware Spring Boot fat jar/war is to extend the org.apache.camel.spring.boot.FatJarRouter class...
