我想首先说我意识到数据库结构很糟糕,但我现在无法改变它.
话虽这么说,我需要在Hibernate(4.2.1)中创建一对多的双向关系,它不涉及主键(只有关系的"父"侧的唯一键)而且没有连接表.表示此关系的外键是从"子"到"父"的后向指针(见下文).我搜索并尝试了各种不同的注释配置而没有运气.我要求的是什么？
GLOBAL_PART
CREATE TABLE "GLOBAL_PART" (
"GLOBAL_PART_ID" NUMBER NOT NULL,
"RELEASES" NUMBER,
CONSTRAINT "GLOBAL_PART_PK" PRIMARY KEY ("GLOBAL_PART_ID"),
CONSTRAINT "GLOBAL_PART_RELEASES_UK" UNIQUE ("RELEASES")
);
PART_RELEASE
CREATE TABLE "PART_RELEASE" (
"PART_RELEASE_ID" NUMBER NOT NULL,
"COLLECTION_ID" NUMBER,
CONSTRAINT "PART_RELEASE_PK" PRIMARY KEY ("PART_RELEASE_ID"),
CONSTRAINT "GLOBAL_PART_RELEASE_FK" FOREIGN KEY ("COLLECTION_ID")
REFERENCES "GLOBAL_PART" ("RELEASES") ON DELETE CASCADE ENABLE
);
参考:
PART_RELEASE GLOBAL_PART
------------------- ------------
PART_RELEASE_ID (PK) GLOBAL_PART_ID (PK)
COLLECTION_ID -------------> RELEASES (UK)
GlobalPart.java
@Entity
@Table(name = "GLOBAL_PART")
@SequenceGenerator(name = "SEQUENCE_GENERATOR", sequenceName = "GLOBAL_PART_SEQ")
public …我一直在尝试让引导程序提前输入工作，但没有任何运气。我已经粘贴了我的代码。我参考了 Jquery-1.9.1 和 typeahead.js。我究竟做错了什么？非常感谢您的帮助！谢谢。
