Hi,
The template does not use the routes configured inside the RouterBuilder. A way
to configure it is by creating the RouteConfigurationBuilder as below.
{code:java}
@Component
public class MyCustomErrorHandler extends RouteConfigurationBuilder {
@Override
public void configuration() throws Exception {
routeConfiguration("my-error-handler").
onException(ConnectException.class)
.handled(true)
.log(LoggingLevel.ERROR, log, "--> Exception: ${exception.message},
Delivery was NOT rolled back");
}
}{code}
Thus you configure it inside the template
{code:java}
routeTemplate("route-template-1")
.templateParameter("input-directory-param-id")
.templateParameter("rest-endpoint-id")
.templateParameter("route-id-param-id")
.from("file:{{input-directory-param-id}}")
.routeConfigurationId("my-error-handler")//He is the configuration. If needed
you can use the template parameter.
.log(LoggingLevel.INFO, log, "--> Read file: ${header.CamelFileName}")
.to("{{rest-endpoint-id}}")
.id("{{route-id-param-id}}")
.log(LoggingLevel.INFO, log, "--> File: ${header.CamelFileName} sent to
rest-endpoint: {{rest-endpoint-id}}");{code}
However, I have seen it has a bug and the template is not using the
RouteConfigurationBuilder. I have found the root cause and I`ll send a PR soon
to solve that.

> Templated route exception handling not working
> ----------------------------------------------
>
> Key: CAMEL-18262
> URL: https://issues.apache.org/jira/browse/CAMEL-18262
> Project: Camel
> Issue Type: Bug
> Components: came-core
> Affects Versions: 3.18.0
> Environment: * Camel 3.18.0
> * Spring-boot 2.7.1
> * OpenJDK 11
> * Maven 3.5.0
> Reporter: j vh
> Priority: Major
> Attachments: camel-template-so.7z
>
>
> Using Route Templates as described here in the Camel docs: [route-template,
> |https://camel.apache.org/manual/route-template.html]I cannot get any
> exception handling to work unless I define it within the class that is
> constructing the template itself.
> Specifically, trying to use global exception handling in the class that
> calls TemplatedRouteBuilder.builder() to build a route from my template.
> Expected exceptions are not caught.
> And there is no .onException() method implementation to customize the
> handling that could be called in the list of fluent methods starting with
> TemplatedRouteBuilder.build().
> I have already posted this, with my example code, in the Camel mailing list.
> Please have a look at the discussion here:
> [mail-archive|[https://lists.apache.org/thread/26kp2tpfbgj9mxpfdr106f36xyj51d7g]]
> This is the hi-level description from that mail article:
> {code:java}
> Hi-level overview:
> - 2 projects: 1 camel template base jar and 1 springboot camel application
> (that builds its route using the template from the other project).
> - the base jar builds a route template
> - the application jar builds a route using the template from the base jar
> - the desire here is to do some extra customization in the application (at
> templated-route creation time) to setup extra exception handling that is not
> included in the base template.
> - I have also tried to define global level exception handling using
> onException() in my application project's configure() method. But this is not
> catching anything either.
> {code}
> There is a overview of the code in the mail article as well. But I also have
> a simplified single spring-boot test project with junit that I can provide if
> needed.
