如何在spring hibernate中连接两个表？

// 实体类1：User
@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    private String name;
    
    // 与另一个表的关联关系
    @OneToOne(mappedBy = "user")
    private UserInfo userInfo;
    
    // 省略getter和setter方法
}

// 实体类2：UserInfo
@Entity
@Table(name = "user_info")
public class UserInfo {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    private String address;
    
    // 与另一个表的关联关系
    @OneToOne
    @JoinColumn(name = "user_id")
    private User user;
    
    // 省略getter和setter方法
}

// DAO接口：UserDao
public interface UserDao {
    User findById(Long id);
    void save(User user);
    void update(User user);
    void delete(User user);
}

// DAO实现类：UserDaoImpl
@Repository
public class UserDaoImpl implements UserDao {
    @Autowired
    private SessionFactory sessionFactory;
    
    @Override
    public User findById(Long id) {
        Session session = sessionFactory.getCurrentSession();
        return session.get(User.class, id);
    }
    
    // 省略其他方法的实现
}

// Service类：UserService
@Service
public class UserService {
    @Autowired
    private UserDao userDao;
    
    public User getUserById(Long id) {
        return userDao.findById(id);
    }
    
    // 省略其他方法的实现
}

// 测试类：UserServiceTest
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
public class UserServiceTest {
    @Autowired
    private UserService userService;
    
    @Test
    public void testGetUserById() {
        Long userId = 1L;
        User user = userService.getUserById(userId);
        System.out.println(user.getName());
        System.out.println(user.getUserInfo().getAddress());
    }
}
