I have updated the jsr330 branch and will merge to trunk once I have a added a few more
tests. The kernel now supports the JSR 330 usage of @javax.inject.Inject, e.g.:
public class SomeBean
{
@Inject @SomeQualifier Thing t;
@Inject
public SomeBean(@SomeQualifier Thing t){}
@Inject
public void setThingA(@SomeQualifier Thing t){}
@Inject @SomeQualifier
public void setThingB(Thing t){}
@Inject
public void installMethod(@SomeQualifier Thing t, @OtherQualifier Thing t2){}
}
If we have the following MC bean
public class MyBean{
@Inject Thing t;
@Weld @Inject Other o;
}
+t+ will be injected from the MC using contextual injection, while +o+ will be injected
from Weld. This is done by maintaining a registry of annotations that should be ignored by
the @Inject annotation plugins, so if the member also has one of those annotations (e.g.
@Weld) we don't create the standard MC injection value metadata for it.
When creating the weld injection we create a weld AnnotatedType for the bean, for which
there is a decorator that looks at the MDR metadata for the bean. I modified the
getAnnotations(), isAnnotationPresent() and getAnnotation() methods to strip out the
@Inject unless @Weld is also present, so that weld does not try to inject into those
members.
To make an MC bean injectable into Weld it needs the @WeldEnabled annotation, e.g.:
If we have the following MC bean
@WeldEnabled
public class McBeanForWeld{
}
