To create a REST API in Spring Boot, you need to define a controller class and annotate it with @RestController. The @RestController annotation combines the functionality of the @Controller and @ResponseBody annotations, making it easier to develop RESTful APIs.
Here's an example of a UserController class that handles HTTP requests for a User resource:
TEXT/X-JAVA
1@RestController
2@RequestMapping("/api/users")
3public class UserController {
4
5 @Autowired
6 private UserService userService;
7
8 @GetMapping
9 public List<User> getAllUsers() {
10 return userService.getAllUsers();
11 }
12
13 @PostMapping
14 public User createUser(@RequestBody User user) {
15 return userService.createUser(user);
16 }
17
18 @GetMapping("/{id}")
19 public User getUserById(@PathVariable("id") Long id) {
20 return userService.getUserById(id);
21 }
22
23 @PutMapping("/{id}")
24 public User updateUser(@PathVariable("id") Long id, @RequestBody User user) {
25 return userService.updateUser(id, user);
26 }
27
28 @DeleteMapping("/{id}")
29 public void deleteUser(@PathVariable("id") Long id) {
30 userService.deleteUser(id);
31 }
