摘　　要：分析数据集成中常见的数据迁移方法及它们的优缺点.利用Hibernate的实体映射功能,说明了如何建立实体映射规则,提出了一种解决多键值依赖的面向对象数据迁移方法.实际应用表明,该方法数据迁移速度快,不仅能够完整地迁移所有数据,同时还能保证数据迁移过程中数据精度的损失在可控范围内.Analyzing common methods of data migration in data integration, and pointing out their advantages and disadvantages. With entity mapping capability of Hibernate, analyzing how to build mapping rules, an orient-object data migration method which resolves dependent on multi-primarykey is put forward. In the actual application it can not only migrate holistically all data, but also guarantee data precision losing within a controllable range in data migration.
