I want to understand how to build REST APIs in Spring Boot. What annotations and structure should I use?

[rushikeshdhande]

You can implement REST APIs in Spring Boot using @RestController and @RequestMapping annotations.

Steps:

1. Create a Controller class using @RestController
2. Use @GetMapping, @PostMapping, @PutMapping, @DeleteMapping for endpoints
3. Follow layered architecture: Controller → Service → Repository
4. Connect database using JDBC or JPA

This structure helps build scalable and maintainable APIs.
