[cdi-dev] Getting interceptor bindings in standard way

[arjan tijms <arjan.tijms@xxxxxxxxx>]

Hi,

A particular issue in CDI is obtaining the interceptor binding annotations from within an interceptor.

Interceptors may use the target bean class for this, but this doesn't work if the interceptor binding was added dynamically. Currently Jakarta spec implementations like e.g. Soteria use Weld specific code for this (and should also contain OWB specific code). 

See: https://github.com/eclipse-ee4j/soteria/blob/master/impl/src/main/java/org/glassfish/soteria/cdi/LoginToContinueInterceptor.java#L314

There's an existing issue for this:

https://issues.redhat.com/browse/CDI-468

There's basically two viable solutions for this:

1. Standardise the key to obtain these from the context. Currently Weld uses "org.jboss.weld.interceptor.bindings". We could define this to be "jakarta.interceptor.bindings"

2. Inject them into the intercept method, e.g. intercept(InvocationContext context, MyBinding myBinding)

Thoughts?

Kind regards,

Arjan Tijms
