Spring Cloud Security配置JWT和OAuth2的集成实现授权管理（四）

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

    private final UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @GetMapping("/{id}")
    public Mono<User> getUserById(@PathVariable String id) {
        return userService.getUserById(id);
    }

}

@Service
public class UserService implements ReactiveUserDetailsService {

    private final UserRepository userRepository;

    public UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Override
    public Mono<UserDetails> findByUsername(String username) {
        return userRepository.findById(username)
                .map(user -> User.withUsername(user.getUsername())
                        .password(user.getPassword())
                        .roles(user.getRoles())
                        .build());
    }

    public Mono<User> getUserById(String id) {
        return userRepository.findById(id);
