Spring Boot CLI
Spring Boot CLI ek COMMAND-LINE TOOL hai jo Groovy scripts se, TURANT Spring applications RUN karne deta hai — bina TRADITIONAL project structure (pom.xml, folders) ke, bina EXPLICIT compile step ke. PROTOTYPING aur QUICK EXPERIMENTS ke liye useful hai.
Practically, PRODUCTION applications mein CLI RARELY use hoti hai — MOST developers directly IDE + Spring Initializr use karte hain. CLI zyaada EDUCATIONAL/DEMO purposes ke liye, ya BAHUT QUICK proof-of-concept scripts ke liye useful hai.
# CLI install (SDKMAN se):
sdk install springboot
# Ek Groovy script directly run karna:
# app.groovy:
@RestController
class HelloController {
@RequestMapping("/")
String hello() { "Hello from Spring Boot CLI!" }
}
spring run app.groovy # koi separate compile step nahi, seedha run- Groovy scripts se, bina traditional project structure ke, run karta hai
- Quick prototyping/POC ke liye useful — production mein RARE
- Modern IDEs mein Initializr built-in hone ki wajah se, CLI ka use ghatta hai
CLI ka MAIN use-case hai — EK IDEA ko TURANT VALIDATE karna, bina PROJECT SETUP OVERHEAD ke. Production applications, TEAM COLLABORATION, aur COMPLEX dependency management ke liye, TRADITIONAL Maven/Gradle project (IDE ke saath) HAMESHA BEHTAR choice hai.
- CLI = quick prototyping, single-file experiments
- Traditional project (Maven/Gradle + IDE) = production, team collaboration
Spring Boot CLI GROOVY use karta hai (Java NAHI) kyunki Groovy ka SYNTAX MORE CONCISE hai, aur IMPLICIT IMPORTS support karta hai — @RestController jaisa annotation likhте hi, Groovy AUTOMATICALLY correct import ADD kar deta hai, bina EXPLICIT import statement ke.
