我正面临将实体插入数据库的问题.我正在使用Hibernate JPA.这是我的数据库结构:
Table : User {CGU_USER_ID as PK}
Table : Industries {CGI_INDUSTRY_ID (PK),CGI_INDUSTRY_NAME}
Table : USER_INDUSTRY_MAP {CUIM_USER_ID (FK),CUIM_INDUSTRY_ID (FK)}
这是我的映射:
@JoinTable(name = "USER_INDUSTRY_MAP", joinColumns = @JoinColumn(name = "CUIM_USER_ID", referencedColumnName = "CGU_USER_ID"), inverseJoinColumns = @JoinColumn(name = "CUIM_INDUSTRY_ID"))
@OneToMany(cascade = { CascadeType.MERGE, CascadeType.REMOVE }, fetch = FetchType.EAGER)
private List<Industry> industrySet;
我得到的例外说:
org.springframework.dao.DataIntegrityViolationException: could not insert collection: [com.keff.gg.domain.User.industrySet#1242]; SQL [insert into CG_USER_INDUSTRY_MAP (CUIM_USER_ID, CUIM_INDUSTRY_ID) values (?, ?)]; constraint [CUSTOMERGATEWAY.FK_CUIM_USER_ID]; nested exception is org.hibernate.exception.ConstraintViolationException: could not insert collection: [com.keff.gg.domain.User.industrySet#1242]
Caused by: java.sql.SQLException: ORA-02291: integrity …hibernate ×1
