Answer:
Spring Boot CLIs: Starter for quick starts, SpringBootApplication with CommandLineRunner for full flexibility.
Step-by-step explanation:
Spring Boot offers two main approaches for building command-line applications:
Spring Boot Starter CLI: This official Spring tool provides a convenient way to manage your project's dependencies and boilerplate.
You can use it to generate a basic CLI application structure, encode passwords, and even run nested shells within your app. It's a great starting point for beginners.
SpringBootApplication with CommandLineRunner:
This approach lets you leverage Spring's full power and flexibility for your CLI app. Annotate your main class with SpringBootApplication and implement the CommandLineRunner interface.
This interface provides a single run method where you can handle command-line arguments, interact with Spring beans, and perform any custom logic needed for your CLI tool.
Remember, Spring Boot also integrates with Spring Shell, a powerful framework for building interactive, text-based CLI experiences with features like autocompletion and command history.
Choose the approach that best suits your project's complexity and desired features. Both Spring Boot Starter CLI and SpringBootApplication with CommandLineRunner can get you started with building robust and efficient command-line applications.
Thus, Spring Boot CLI for quick starts, SpringBootApplication with CommandLineRunner for full flexibility.
