如何在spring boot中将多个数据保存到数据库

@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;
    private String email;

    // 省略getter和setter方法
}

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
}

spring.datasource.url=jdbc:mysql://localhost:3306/mydb
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;

    public void saveUsers(List<User> users) {
        userRepository.saveAll(users);
    }
}

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    @PostMapping("/users")
    public void saveUsers(@RequestBody List<User> users) {
        userService.saveUsers(users);
    }
}
