休眠外键

[英]hibernate foreign key

原文 2009-11-02 06:59:15 9 1 java/ hibernate/ foreign-keys/ foreign-key-relationship

i have entity A that has foreign key to entity B, does entity B need to have foreign key back to entity A? 我的实体A拥有对实体B的外键，实体B是否需要将外键返回到实体A？ if yes, how? 如果是，如何？ coz entity B, id already used for primary key coz实体B，ID已用于主键

entity A --> id, entity_a_name, foreign_key_entity_B 实体A-> ID，entity_a_name，foreign_key_entity_B
entity B ---> id, entity_b_name 实体B ---> id，entity_b_name
