The Spark-rest component allows to define REST endpoints using the Spark REST Java library which has a nice using the Rest DSL.

| Spark Java requires Java 8 runtime. |

from("spark-rest:get:/hello/*/to/*")
.transform().simple("Bye big ${header.splat[1]} from ${header.splat[0]}"); |
SparkRouteBuilder
If you use Java code, then you can use the class org.apache.camel.component.sparkrest.SparkRouteBuilder to define routes using a Spark DSL, as shown below
Rest DSL
Apache Camel provides a new Rest DSL that allow to define the REST services in a nice REST style.
For example we can define a REST hello service in Java DSL as shown below:
![]() Code Block |
return new SparkRouteBuilderRouteBuilder() {
@Override
public void configure() throws Exception {
getrest("/hello/:{me}").get()
.route().transform().simple("Bye ${header.me}");
}
}; |
When using the SparkRouteBuilder, then you can define Camel routes using the REST verbs, such as get, post, put, delete etc.
And the same example in XML DSL would be
![]() Code Block |
|
|
<camelContext xmlns="http://camel.apache.org/schema/spring">
<rest uri="/hello/{me}">
<get>
<route>
<transform>
<simple>Bye ${header.me}</simple>
</transform>
</route>
</get>
</rest>
</camelContext>
|
See more details at the Rest DSL.
More examples
There is a camel-example-spark-rest-tomcat example in the Apache Camel distribution, that demonstrates how to use camel-spark-rest in a web application that can be deployed on Apache Tomcat, or similar web containers.
