Adding to Camel Context

Spring XML

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:camel="http://camel.apache.org/schema/spring" xmlns:to="http://camel.apache.org/schema/spring"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

    <bean id="properties" class="org.constretto.camel.ConstrettoComponent">
        <constructor-arg>
            <array>
                <value>classpath:test.properties</value>
            </array>
        </constructor-arg>
    </bean>

    <camel:camelContext id="testContext" xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="direct:input"/>
            <to uri="log:{{outlogger}}" id="output"/>
        </route>

    </camel:camelContext>

</beans>

Or you can combine it with the Constretto-Spring XML namespace support

                <!-- ref: links will be looked up from the Spring context -->

Spring Java Context

@Configuration
public static class Context extends SingleRouteCamelConfiguration {

    @Bean
    public static ConstrettoConfiguration constrettoConfiguration() {
        return new ConstrettoBuilder(false)
                .createPropertiesStore()
                .addResource(Resource.create("classpath:test.properties"))
                .done()
                .getConfiguration();
    }

    @Bean
    public ConstrettoComponent properties() {
        return new ConstrettoComponent("ref:constrettoConfiguration");
    }

    @Override
    protected void setupCamelContext(final CamelContext camelContext) throws Exception {
        camelContext.addComponent("properties", properties());
    }

    @Override
    public RouteBuilder route() {
        return new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                from("direct:input").routeId("javaContextInputRoute").to("log:{{outlogger}}");
            }
        };
    }
