Still learning… just taking it one step at a time.

Some days it clicks, some days it doesn’t, but I keep showing up.
Little by little, things start to make more sense.

Not rushing anything. Just growing!

🚀 Spring Shell — Build CLI Apps with Spring Boot

Most developers use Spring Boot to build REST APIs.
But what if you want to build a command-line tool instead?
That’s where Spring Shell comes in.

It lets you create interactive CLI applications using Spring Boot.

Instead of calling APIs like this:

POST: /users

You run commands in the terminal:

shell:> create-user --name=Sivlay
shell:> user-list

🔑 Key Features

✅ Build CLI tools using Spring Boot
✅ Define commands with simple annotations
✅ Automatic command parsing & help menu
✅ Supports arguments and options
✅ Perfect for admin tools and DevOps utilities

Examples:


public class UserCommand {

("Create new user")
public String createUser(String name) {
return "User created: " + name;
}

}

Run in terminal:

shell:>create-user Sivlay

🔥 What is a Bean in Spring?

A Spring Bean is an object that is instantiated, configured, and managed by the Spring IoC(Inversion of Control) container, including its lifecycle and dependencies.

👉 Not every object is a Bean
👉 Only objects managed by Spring are Beans

💡 Spring creates Beans via👇
✅Stereotype annotations: , , ,
✅Java configuration: inside

🔥 vs vs (Spring Boot)

They work the same as Spring Beans!
Same behavior, different meaning. Use the right annotation for clean architecture 👇

🔥 vs in Spring Boot

If you’re learning Spring Boot, this is one of the first things that can confuse you.Both look similar, but they are used for different purposes!!

Let’s make it simple:


👉 Used for Web MVC applications
👉 Returns HTML views (Thymeleaf, JSP, etc.)

When you use , Spring expects you to return a view name, not JSON. If you want to return JSON with , you must add:
Otherwise, Spring will try to find a view file.


👉 Used for REST APIs
👉 Returns JSON automatically

= +
No need to add .

💡 When Should You Use Each?
✅ Use
• When building server-rendered web apps
• When using Thymeleaf or JSP

✅ Use
• When building REST APIs
• When building microservices
• When your frontend is React, Angular, Vue, Mobile App
