Description

In our application we have a base rout builder class in which we would like to intercept all REST routes executions (REST requests)

 

public abstract class BaseRouteBuilder extends RouteBuilder {
@Autowired
protected RestInterceptorProcessor restInterceptorProcessor;

@Override
public void configure() throws Exception {
    interceptFrom("rest:.*")
            .process(restInterceptorProcessor);
} 

All our routes extend this class and are constructed like the code below:

 

 

@Component
public class MySampleRestCamelRestComponent extends BaseRouteBuilder { 
@Override
public void configure() throws Exception {
    super.configure();

    rest("/api/v1/some-endpoint")
                .consumes(MediaType.APPLICATION_JSON_VALUE)
                .produces(MediaType.APPLICATION_JSON_VALUE)
                .get("/objects")
                    .id("getObjects")
                    .to("direct:rest-fetch-objects")
}

This approach worked fine in Camel 3., but in Camel 4. my processor is not executed.

I've made some investigation and:

• when we skip the pattern and just use interceptFrom().process(restInterceptorProcessor) - the processor is executed on REST request, but also for other requests like f.e. seda:
• when I've debugged Camel source code while using the rest:* or rest:.* patterns, the URI matcher returns true (URI start with "rest://get://api/v1/some-endpoint" etc.) within the class org.apache.camel.model.RouteDefinitionHelper / method

private static void doInitInterceptors(
            CamelContext context, RouteDefinition route, List<ProcessorDefinition<?>> upper,
            List<InterceptDefinition> intercepts,
            List<InterceptFromDefinition> interceptFromDefinitions,
            List<InterceptSendToEndpointDefinition> interceptSendToEndpointDefinitions)
 

, but still my processor is not executed after REST request.

Could you please check this issue?
