Global onException and interceptor definitions outside Camel context? - apache-camel

Question

I have multiple Camel applications (written in Spring DSL) and they all share the same onException and a number of interceptors defined globally in the camel context. I'm wondering if it's possible to have onException and interceptors defined in a separate XML file somewhere in the class path and include or inject it into camel context when the app starts. Java DSL has adviceWith, but is there such thin in Spring DSL as well?

Answer 1

This is not possible currently. However in Camel 3.12 onwards we are adding such feature which is called route configuration
You can read about it here: https://camel.apache.org/manual/latest/route-configuration.html

Answer 2

My temporary "solution" was to store the route configuration XML files in some pre-defined location, e.g. "/routeConfigurations" and I added the following code to my SpringBoot application class:
#Bean
public void initRouteConfigurations() throws Exception {
SpringCamelContext springCamelContext = (SpringCamelContext) camelContext;
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
Resource[] routeConfigurations = resolver.getResources("/routeConfigurations/*");
for (Resource r : routeConfigurations) {
InputStream is = r.getURL().openStream();
ModelParser parser = new ModelParser(is, "http://camel.apache.org/schema/spring");
Optional<RouteConfigurationsDefinition> definitionsOptional = parser.parseRouteConfigurationsDefinition();
RouteConfigurationsDefinition routeConfigurationsDefinition = definitionsOptional.get();
springCamelContext.addRouteConfigurations(routeConfigurationsDefinition.getRouteConfigurations());
}
}
