如何使用Spring Boot Crudrepository将数据插入到同一数据库的两个表中？

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

    private String name;
    private String email;
    // 其他属性和关联关系

    // getter和setter方法
}

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

    private String city;
    private String street;
    // 其他属性和关联关系

    // getter和setter方法
}

public interface UserRepository extends CrudRepository<User, Long> {
    // 其他自定义的查询方法
}

public interface AddressRepository extends CrudRepository<Address, Long> {
    // 其他自定义的查询方法
}

@Service
public class UserService {
    private final UserRepository userRepository;
    private final AddressRepository addressRepository;

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

    public void saveUserAndAddress(User user, Address address) {
        userRepository.save(user);
        addressRepository.save(address);
    }
}

@RestController
@RequestMapping("/api/users")
public class UserController {
    private final UserService userService;

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

    @PostMapping
    public ResponseEntity<User> createUser(@RequestBody UserRequest userRequest) {
        // 从请求中获取需要插入的数据
        User user = new User();
        user.setName(userRequest.getName());
        user.setEmail(userRequest.getEmail());

        Address address = new Address();
        address.setCity(userRequest.getCity());
        address.setStreet(userRequest.getStreet());

        // 调用保存数据的方法
        userService.saveUserAndAddress(user, address);

        return ResponseEntity.ok(user);
    }
}
