Spring Basics XML Setter Injection With Custom Method Names

Let’s have a look at how to inject beans using setters with a custom method name.

Spring Basics Wiring Beans With Xml Configuration

If you have to work with legacy Spring applications, chances are you will have to know how XML-based configuration works. Although Java configuration is preferred for new applications, sometimes you just don’t have a choice, so you’d better be comfortable with it.

Quick Vim Tip: Change Text Between White Space
