🚀 Building Spring by Example

#java #programming #learning #beginners

When I started learning Spring, I noticed something about the tutorials I found.

Many showed how to use a feature, but not always why it worked or when you should choose one approach over another.

I learn best by building things and documenting what I discover, so I decided to start a project called spring-by-example.

Instead of creating one large application, I’m building a collection of small, focused examples—each one exploring a single Spring concept with clear explanations, tests, and documentation.

So far I’ve worked through:

Spring Beans
Dependency Injection
Constructor Injection
Setter Injection
Field Injection
Choosing an Injection Strategy

I’m sharing the journey here as I continue learning. My hope is that, over time, this grows into a resource that helps other developers understand Spring one concept at a time.

If you’ve learned Spring, what concept took you the longest to fully understand?
