Re: Hooking a custom InjectionProvider into the IoC container
After some more experimentation, I've corrected an error in my original
contribution method. It should've read:
public static void contributeInjectionProvider(
OrderedConfigurationInjectionProvider2 configuration,
MasterObjectProvider masterObjectProvider,
ObjectLocator locator,
SymbolSource symbolSource,
AssetSource assetSource)
{
configuration.add(BeckonLogger, new
BeckonLoggerInjectionProvider(), before:Default);
}
When I include this method in my AppModule, my InjectionProvider
implementation get a chance to provide implementations for Pages and
Components, which is most of what I'd like to do. However, I'd also like my
InjectionProvider to act on objects built during the Registry Startup
phase. In particular, I configure a database in a submodule method
annotated with @Startup. @Inject-annotated fields of objects built in that
phase are not seen by my InjectionProvider.
I found a thread from last year that discusses a very similar goal:
http://markmail.org/thread/ny4xefhxzuwrus3e. That thread culminated in
tapestry-cdi: https://github.com/magnuskvalheim/tapestry-cdi . I tried to
follow the same approach--contributing my InjectionProvider in a totally
separate Module which tapestry should've seen via autoloading, but I can't
seem to get autoloading right. I added the following block to my pom.xml:
plugin
groupIdorg.apache.maven.plugins/groupId
artifactIdmaven-jar-plugin/artifactId
version2.3.2/version
configuration
archive
manifestEntries
Tapestry-Module-Classescom.beckon.util.log.BeckonLoggerInjectionModule/Tapestry-Module-Classes
/manifestEntries
/archive
/configuration
/plugin
This correctly adds the Tapestry-Module-Classes line to the MANIFEST.MF of
jars built using mvn jar:jar, but I don't believe it affects the archive
built by mvn jetty:run. In any case, my LoggerInjectionModule doesn't
appear in the list of modules added by ioc.RegistryBuilder.
Any suggestions regarding contributing InjectionProviders before the
Startup phase or troubleshooting autoloading when using the jetty:run maven
goal?
Thank you,
- Pavel

Hooking a custom InjectionProvider into the IoC container
Tapestry Users,
I'd like to contribute an
InjectionProvider2http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/transform/InjectionProvider2.html
into
the chain that processes @Inject annotations. The cookbook example that
illustrates the chain of command
patternhttp://tapestry.apache.org/ioc-cookbook-patterns.html cites
how Tapestry IOC's own injection provider is built. The example says, And,
of course, other contributions could be made in other modules ... if you
wanted to add in your own form of injection. So, I tried copying a similar
method into my AppModule:
public static void contributeInjectionProvider2(
OrderedConfigurationInjectionProvider2 configuration,
MasterObjectProvider masterObjectProvider,
ObjectLocator locator,
SymbolSource symbolSource,
AssetSource assetSource)
{
configuration.add(BeckonLogger, new InjectionProvider2() {
public boolean provideInjection(PlasticField field,
ObjectLocator locator1, MutableComponentModel componentModel) {
if
(field.getTypeName().equals(com.beckon.app.util.log.BeckonLogger)) {
field.inject(BeckonLoggerImpl.getLogger(field.getPlasticClass().getClassName()));
return true;
}
return false;
}
});
}
But that gives me the following error:
java.lang.IllegalArgumentException: Contribution
com.beckon.app.services.AppModule.contributeInjectionProvider2(OrderedConfiguration,
MasterObjectProvider, ObjectLocator, SymbolSource, AssetSource) (at
AppModule.java:92) is for service 'InjectionProvider2', which does not
exist.
Is there a different way that I should contribute my InjectionProvider2?
More generally, what is the best way to add a custom form of injection?
More generally still, my overarching goal is to be able to instiate my own
logger with the name of the owning class and to use @Inject to describe the
dependency--is there a way to customize or otherwise use one of the
existing InjectionProviders to do that?
Thank you in advance,
- Pavel
