Spring Boot REST API

REST API with Spring Boot

Spring Boot helps create production-ready APIs quickly.

Layers

Controller → Service → Repository → Database

Controller Example

@RestController
@RequestMapping("/api/users")
public class UserController {

    @GetMapping("/{id}")
    public User getUser(@PathVariable Long id) {
        return userService.findById(id);
    }
}

Best Practices

Use DTOs, validation, centralized exception handling and OpenAPI documentation.
