Hi,
I have implemented the following example
http://cwiki.apache.org/SM/order-file-processing.html and it is working
fine. I need to add few modifications to my camel context.xml. My question
is , is it possible to add spring aspects to camel-context.xml i.e
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:aop="http://www.springframework.org/schema/aop";
xmlns:context="http://www.springframework.org/schema/context";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://activemq.apache.org/camel/schema/spring
http://activemq.apache.org/camel/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd";>
<context:annotation-config />
<aop:aspectj-autoproxy/>
<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring";>
<package>org.camel.su</package>
</camelContext>
<bean id="firstAspect" class="org.aspect.FirstAspect"/>
</beans>
I have my pointcuts defined in the java code using spring annotations.
The code is as follows:
@Aspect
public class SystemArchitecture {
@Pointcut("execution(* *(..))")
public void myFirstPointCut()
{
}
}
package org.aspect;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
@Aspect
public class FirstAspect {
@Around("SystemArchitecture.myFirstPointCut()")
public void firstAspect(ProceedingJoinPoint joinPoint)
{
System.out.println("PRINTING FIRST ASPECT");
try {
joinPoint.proceed();
} catch (Throwable e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
If defining aspects in camel-context.xml is possible, then how do I define
aspects on my RouteBuilder class.Because I want a particular piece of code
to be always executed before my route builder class is called and I do not
want to embed that code in the routebuilder class.
For ex: If I do some thing like this below,
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:aop="http://www.springframework.org/schema/aop";
xmlns:context="http://www.springframework.org/schema/context";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://activemq.apache.org/camel/schema/spring
http://activemq.apache.org/camel/schema/spring/camel-spring.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd";>
<context:annotation-config />
<aop:aspectj-autoproxy/>
<camelContext id="camel"
xmlns="http://activemq.apache.org/camel/schema/spring";>
<routeBuilder ref="someRouterBuilder"/>
</camelContext>
<bean id="firstAspect" class="org.aspect.FirstAspect"/>
<bean id="someRouterBuilder" class="org.camel.su.MyRouteBuilder"/>
</beans>
public class MyRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception {
System.out.println("IN ROUTE BUILDER#####");
// from our camelService which is called by the file poller
from("jbi:service:http://servicemix.apache.org/example/orderProcessing";)
// we process the received order xml
.process(new OrderProcessor())
// and send the result xml back to the file sender
.to("jbi:service:http://servicemix.apache.org/example/fileSender";);
}
}
I get an exception is saying that routeBuilder should of type
org.apache.camel.builder.RouteBuilder. I do not understand why I am getting
this exception as my RouteBuilder class is already extending the camel
RouteBuilder class.
Please help me these queries.I thank you all for your time.
