In Grails there is a custom solution to optimize autowiring by name. Grails autowires all objects that are retrieved from Hibernate (GORM) . That's why the performance of autowiring is really critical for Grails.
This is the BeanFactory implementation Grails uses: https://github.com/grails/grails-core/blob/master/grails-core/src/main/groovy/org/grails/spring/beans/factory/OptimizedAutowireCapableBeanFactory.java (or rev 6d3604a if that link is broken)
It would be nice to have some caching like this directly in Spring. Some usecases (I was perf. testing with) were 300% faster with this change at the time I added that optimization, so it's quite important for Grails applications. There are some drawbacks in the solution used in Grails. The use of the optimizations can be skipped for a single class by making the class implement the Aware marker interface.
I wouldn't recommend to use a similar implementation directly in Spring, but I'd like to see autowiring by name optimized for performance directly in Spring.
Affects: 4.0.5

any updates on this issue? The issue https://jira.grails.org/browse/GRAILS-11965 in Grails Jira depends on this issue. I assume we will use the previous solution for 3.0 GA because of the current release schedule (GA target date in March). We would like to get rid of custom solutions in the long run so it would be nice if this issue gets solved in Spring 4.2 .
