Subject [jira] Closed: (TAP5-977) Using @Inject on a private field of type Logger (in a service implementation) fails
Date Tue, 23 Feb 2010 00:00:50 GMT

     [ https://issues.apache.org/jira/browse/TAP5-977?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Howard M. Lewis Ship closed TAP5-977.
-------------------------------------

    Resolution: Invalid

It is necessary to use @InjectResource, to indicate that the thing (the Logger) being injected
is a resource specific to the service, rather than a general object provided via the MasterObjectProvider
service.

> The fact that the MasterObjectProvider was invoked to resolve the value for the field
is wrong; the Logger is a resource of the service, not a dependency on another service, and
should not need to be resolved that way.
