[rules-users] kie-sprind xsd for spring 4

[Mark Proctor]

I should add the private fields don’t really do anything in this example, they are just placeholders for the annotations, and it’s the annotations that are used to build the CDI Beans. Potentially you could make  the “name” attribute optional, and if it doesn’t exist it would use the method or class name.

We could probably allow Qualifiers to be used, so that we get type safe injection, instead of using String names. The qualifier can only be used on one “producer” point, i.e. a single place in any Config file.

@KBaseConfig(name=“kbase1”, packages=“my.domain.fld, my.domain.fld2" )
public class kbase1Config {

    @KSessionConfig(name=“ksession1”, clockType=“pseudo”) 
    @QualifiedBinding( MyKSession.class )
    private KieSession kieSession1;

    @KSessionConfig(name=“ksession2”, clockType=“realtime”) 
    private KieSession kieSession2;
}


public class MyApp {
    @Inject @MyKSession;
    private KieSession ksession1;
}

I really want to avoid any method code, other than configuring say listeners. Ideally we’d be looking for something like below, that mirrors what we have in the xml already, and avoids  authoring any methods at all. I know I could do this in CDI, but I don’t know about Spring. In CDI I can scan for usages of @KBaseConfig. Where I find a @KBaseConfig I can populate the main CDI beans infrastructure, so it treats xml configuration and annotation configuration the same.
