Hello.
i am trying to use the aggregator pattern in a route
and i get this error:
"Cannot find class
[org.apache.camel.processor.aggregate.AggregationStrategy]"
i also added camel-core dependency in pom.xml :
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-core</artifactId>
<version>2.6.0</version>
</dependency>
this is an example implementation of the aggregator strategy that i use
package de.edigrid.util.servicemix;
import org.apache.log4j.Logger;
import org.apache.camel.Exchange;
import org.apache.camel.processor.aggregate.AggregationStrategy;
import org.springframework.stereotype.Component;
@Component
public class MyAggregationStrategy implements AggregationStrategy {
Logger logger = Logger.getLogger(MyAggregationStrategy.class.getName());
public Exchange aggregate(Exchange oldExchange, Exchange newExchange) {
if (oldExchange == null) {
return newExchange;
}
String body1 = oldExchange.getIn().getBody(String.class);
String body2 = newExchange.getIn().getBody(String.class);
oldExchange.getIn().setBody(body1 + body2);
logger.info("Aggregation current state for "+
oldExchange.getIn().getHeader("CamelFileName") +": "+ oldExchange.getIn());
return oldExchange;
}
}
the service-bundle config:
<bean id="aggregatorStrategy"
class="de.edigrid.util.servicemix.MyAggregationStrategy" autowire="byName"/>
<osgi:service id="aggregatorStrategyService" ref="aggregatorStrategy"
interface="org.apache.camel.processor.aggregate.AggregationStrategy" />
this is the route:
<beans ...>
<classpath>
<library>osgi:org.springframework.osgi.core</library>
<library>osgi:org.milyn.smooks.osgi</library>
</classpath>
...
<osgi:reference id="aggregatorStrategyService"
interface="org.apache.camel.processor.aggregate.AggregationStrategy"
bean-name="aggregatorStrategy"/>
<camelContext xmlns="http://camel.apache.org/schema/spring"
id="camelContext">
<route id="TEST">
<from uri="file://"/>
<aggregate strategyRef="aggregatorStrategy">
<correlationExpression>
<simple>1</simple>
</correlationExpression>
<to uri="direct://SPLITTER"/>
</aggregate>
</route>
<route id="TEST2">
<from uri="direct://SPLITTER"/>
<to uri="file://"/>
</route>
</camelContext>
</beans>
Can anyone please help ?
Thank you,
Cristian
