Load interceptors in XML file in camel application based on spring
boot
I am able to separate out the route definitions and rest-dsl routes in
separate XML files in the folders camel and camel-rest in my Camel
Application based on Spring boot. They are also loaded successfully upon
startup.
I now want to add interceptors to the routes so that I can have cross
cutting concerns like caching to the routes.
For that I want to use the interceptFrom camel feature so that globally all
routes are intercepted. Ido not want to pollute the routes with the
intercept logic
The issue I am facing is I am not sure If adding the the interceptFrom tags
in XML file and loading them is supported or not. I want them to be loaded
so that it would be read and added to the camelcontext automatically. I
cannot add them as part of the route definitions which I have added them in
the xml file in camel folder.
Can someone advise me on the correct approach to load interceptors in my
camel boot application based on spring boot.

You need to do the XML as a regular spring xml file with <beans> and
all that stuff.

Hi,
I tried to use *@ImportResource* but I get the error as below,
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line
1 in XML document from class path resource [interceptors.xml] is invalid;
nested exception is org.xml.sax.SAXParseException; lineNumber: 1;
columnNumber: 61; cvc-elt.1: Cannot find the declaration of element
'camelContext'.

at
org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:336)
~[spring-beans-4.3.3.RELEASE.jar:4.3.3.RELEASE]
My *interceptors.xml* has the below content,
<camelContext xmlns="http://camel.apache.org/schema/spring">
<interceptFrom>
<log message="Inside Interceptor" />
</interceptFrom>
</camelContext>
I used *@importResource* as below in my Spring Boot application class
,
@SpringBootApplication
@ImportResource("interceptors.xml")
public class CompositeApplication {
}
Can you please help me on this.
Thanks,
Sridhar

Hi,
Thanks for your response. I will try importing the xml file with
interceptors with the required namespace.
I need another clarification related to the interceptors. There is an
intercept strategy which I see is available in camel.
Want to understand the use case for that. Is it an another alternative to
using the interceptFrom tag to intercept the requests and apply cross
cutting concerns like logging, caching etc. If so, is there any general
recommendation on when we can use that instead of the interceptFrom tag.
Thanks
Sridhar

Hi
The <routes> and <rests> XML file do not support interceptors and the likes.
You can however use Spring Boot @ImportReource (or whatever that
annotation is named) to load a plain Spring XML file, where you can
define <camelContext> and do it the old fashion way.
