This video explains the dependecy injection that occurs through setter injection or non-constructor autowiring of dependency beans.
- [Instructor] In the previous video,…we introduced the first part of bean-specific initialization…and that was the constructors being called…and the beans themselves being instantiated.…Once all of the beans have been instantiated…and all of the required dependencies injected…with those constructor-level injections,…we now have fully qualified classes ready to be used.…However, Spring then goes through each of those classes…and modifies them through the setter argument.…When we look at the big picture of where we're at,…you'll see that we have all of the beans instantiated…and now we're calling the setters,…but setter injection doesn't just include those methods…with a set annotation.…
Once all of these beans have been created,…all of those methods with set property…will definitely be called…if they are appropriately constructed…through property injection or autowiring.…However, field-based injection also occurs here.…If you have a field,…even though we specifically spelled out the reasons…why we shouldn't do field-level injection,…
