Reuben Pasquini commented on CDI-377:
-------------------------------------
@Mark - Maven 3.1 may be ok with @Inject annotations - for example - guice is lazy in its
annotation processing, so guice will only inject a mavin class if it's required by
some class needed at runtime:
class Plugin { ... @Inject() public Plugin( MavinThing thing, ... ) { ... } ... }
In other words - mavin's IOC world can exist along side some plugin's IOC world
assuming the two worlds are working with their own set of classes.
I guess OSGi is designed for this kind of plugin dso hell ...
I think CDI is causing problems, because it eagerly allocates @Singleton classes that may
not be needed at runtime, and may not have all dependencies available either.
There are several ways CDI could make itself a more friendly JSR330 neighbor.
It would be great if either or both of:
o. CDI ignored jars that do not include a beans.xml
o. CDI provided some outside-the-jar override mechanism in a .war or .ear or whatever
file like WEB-INF/web.xml or the app-root META-INF/beans.xml:
<cdi-config><exclude-jar>guava.jar</...></cdi-config>
Something like that ...
automatic JSR-330 annotation processing problematic
---------------------------------------------------
Key: CDI-377
URL:
https://issues.jboss.org/browse/CDI-377
Project: CDI Specification Issues
Issue Type: Bug
Components: Java EE integration
Affects Versions: 1.1.PFD
Environment: glassfish-4
Reporter: Reuben Pasquini
Labels: CDI, guava, guice
Fix For: 1.1.PFD
The jsr-330 dependency injection annotations (javax.inject.*) find use in javase
environments using IOC packages like guice.
Adding a dependency on a jar that uses guice or whatever in a javase environment
to a war deployed to a jee7 container
results in CDI processing annotated classes intended for
app-managed injection. See this ticket filed with guava for a concrete example:
