Re: [Springframework-developer] Spring / HiveMind Integration

[Rob H. <ro...@ca...>]

Howard,

I think it will be quite simple to integrate HiveMind services into 
Spring. As I see it we need a HiveMindRegistryFactoryBean to create the 
Registry instance and then a HiveMindServiceFactoryBean that uses the 
Registry to lookup a given service. By default the 
HiveMindServiceFactoryBean would use the Spring bean name to lookup a 
service in the Registry, but users could configure a different service 
name using DI. With this mechanism, users can create one instance of 
Registry within a Spring application and then access many services from 
that Registry.

If I have time today, I'll work on this. If not, I'll work on it next 
week some time.

I must admit I haven't had a chance to get a good look at HiveMind, but my understanding is that it is a DI container that provides service wiring and interception, much in the same vein as the Spring Container.  From the outset the two containers seem to be mutally exclusive rather than complimentary.
