In the project , I've been dynamically loading Apache Camel routes during runtime.
Current environment includes Spring 2.7.4, Apache Camel 3.18.0, and JDK 17
private void fromFile(final Path filepath) throws Exception {
final byte[] routeDefinitionBytes = Files.readAllBytes(filepath);
final Resource resource = ResourceHelper.fromBytes(filepath.toString(), routeDefinitionBytes);
final ExtendedCamelContext extendedCamelContext = camelContext.adapt(ExtendedCamelContext.class);
extendedCamelContext.getRoutesLoader().loadRoutes(resource);
}
Now migrating project to utilize Apache Camel 4.0.0-RC1
, Spring Boot 3.1.1
, and continue to use JDK 17
. The issue facing is that the adapt() method isn't available in the newer version of Apache Camel, rendering your existing code non-functional.
I'm seeking a viable solution that can allow me to continue reading route definitions from a file and inject them into an Apache Camel context at runtime in Apache Camel 4.0.0-RC1
. Any recommendations would be much appreciated.
For such a need, you can rely on the utility method PluginHelper#getRoutesLoader(CamelContext)
but behind the scenes, the new logic is to call getCamelContextExtension()
on the camel context to get the ExtendedCamelContext
, then get the plugin that you want to use thanks to the method ExtendedCamelContext#getContextPlugin(Class)
.
So your code would then be:
private void fromFile(final Path filepath) throws Exception {
final byte[] routeDefinitionBytes = Files.readAllBytes(filepath);
final Resource resource = ResourceHelper.fromBytes(
filepath.toString(), routeDefinitionBytes
);
PluginHelper.getRoutesLoader(camelContext).loadRoutes(resource);
}
