Caused by: org.hibernate.DuplicateMappingException: Table

首先此错误发生在HibernateJpa @OneToMany 中

@OneToMany(targetEntity = EveBluePrintsResearchMaterialSkills.class,cascade = CascadeType.ALL)
@JoinColumn(name="blue_prints_id")
private Set<EveBluePrintsResearchMaterialSkills> bluePrintsResearchMaterialSkills;

发生错误的原因是因为JoinColumn(name="blue_prints_id") 中的列不明确，需要在子表中的关联列指定标识

@Column(name = "blue_prints_id")
private Integer bluePrintsId;
