我正在使用derby数据库并休眠以自动生成模式。 但是，在为所有实体生成SQL时，并未将Table创建到数据库中。 代码在两个实体类之间具有@OneToMany关系，并且父表也包含EmbeddedID。 Hibernate配置文件和Entities类如下。

的hibernate.cfg.xml

Answer 1

我的错，那只是一个愚蠢的错误。 由于@GeneratedValue不适用于String类型，因此未创建SOItemDetails表，该表应为int类型。 现在需要在SOItemDetails实体类中进行以下更改。

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name = "SO_ITEM_DTLS_ID", unique = true, nullable = false, length = 100)
    int soItemDtlsRecordNo;
