摘　　要：在开发J2EE应用系统中,在进行数据库操作时,使用传统的JDBC来处理数据对象之间的关联关系会非常繁琐。Hibernate通过O/R Mapping将表间关系转化为实体之间的关系,这种关系通过在映射文件中加以声明,较简单地解决了这个问题。Hibernate的关联映射包括一对一,一对多,多对多3种。对这3种关联关系进行系统的分析研究,使得读者对Hibernate的关联映射有一定了解。When we develop J2EE application system, especially manipulating database, it＇s comparatively complicated according to JD- BC. Hibernate transfers the relationship between tables to the relationship between objects, and this relationship is announced in the mapping files, which easily solove the problem. The association relationship ineudes one-to-one, one-to-many and many-to-many. This paper offers a systemic analysis of the mapping relatonship, which makes readers acquaint thesselves with it.
