Hadrian Zbarcea commented on CAMEL-4256:
----------------------------------------

I attached a patch that should give an idea of what I proposed in this issue. 
There are few more things remaining to be done:
 * add a MappedEndpointConfiguration extends DefaultEndpointConfiguration that 
takes all the parameters and stores them in a Map.This will be the class used 
by default by the DefaultEndpoint and will assist in migration and will 
preserve backwards compatibility
 * validation, the part described by Keith Babo above, which I didn't touch on. 
It will require an extra dependency in camel-core on javax.validation.
 * toUriFormat is fairly easy, but I need to define a few annotations like 
@ProviderConfiguration, @ConsumerConfiguration that would mark some parameters 
as making sense only one one side of the messaging channel.

Once the above is done we can start tackling components one by one and add 
better unit testing for supported configurations.

Please review and comment (or nod). I will not commit attached patch for a few 
days.

> One of the key missing pieces from the API is the explicit concept of 
> EndpointConfiguration. We use URIs for that, ant that's great, but we don't 
> have it in the API. Some components do have an informal version though.
> I am proposing adding an EndpointConfiguration interface:
> {code}
> public interface EndpointConfiguration {
>   void fromUri(String uri);
>   String toUri();
> }
> {code}
> and maybe other methods, we could also use URI instead of string for 
> pre-parsing. Same as with other concepts the default implementation would be 
> in impl and components would extend that and add fields for configuration 
> parameters. 
> This would solve problems related to URI uniqueness to a good extent as 
> toUri() should always place parameters in the same order. The Endpoint 
> interface would change though.
> The main advantage would be that we can annotate parameters and use 
> javax.validation to specify if a field is @ProducerOnly, @ConsumerOnly for 
> example, which may exclude them from toUri() (yes, there are some impacts, 
> the id uri would be different than the config uric). We could annotate them 
> with @Secret to indicate that at least the value should not appear in clear 
> in the uri, etc. We could also add an @Default("value"), allowing us to 
> exclude from the uri fields set on the default value (even if the filed was 
> explicitly set) and so on.
> This would also make static validation possible unit testing configuration 
> would be vastly simplified and we could improve coverage. We can do it in an 
> incremental way without a big impact on existing components (especially 
> outside camel) via changes in DefaultEndpoint. I am working on a prototype, 
> but feedback is highly appreciated.
