使用java Spring从Oracle数据库返回创建的ID

// 实体类
@Entity
@Table(name = "your_table_name")
public class YourEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    // 其他字段和方法
}

// 数据访问层
@Repository
public class YourDao {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    public Long insertEntity(YourEntity entity) {
        KeyHolder keyHolder = new GeneratedKeyHolder();
        jdbcTemplate.update(connection -> {
            PreparedStatement ps = connection.prepareStatement("INSERT INTO your_table_name (column1, column2) VALUES (?, ?)", Statement.RETURN_GENERATED_KEYS);
            ps.setString(1, entity.getColumn1());
            ps.setString(2, entity.getColumn2());
            return ps;
        }, keyHolder);

        return keyHolder.getKey().longValue();
    }
}

// 业务逻辑层或控制器
@Service
public class YourService {
    @Autowired
    private YourDao yourDao;

    public Long createEntity(YourEntity entity) {
        return yourDao.insertEntity(entity);
    }
}
