Spring containers allow injection of List, Set, Map, or Properties objects to other Spring-defined beans through <property> tags. The following recipe will distinguish between XML-based and JavaConfig context definitions when it comes to implementing type-safe injection.
Getting started
Reopen ch02-xml and ch02-jc for this recipe. We will be injecting a few POJO objects to both of the containers in our projects.
How to do it...
Perform the following steps to auto-wire Collections and Properties components:
