标识符映射的列数错误：

Question

任何人都可以帮助我 我有这个错误 由以下原因引起：org.hibernate.MappingException：标识符映射列数错误：com.twins.FootFans.model.MemberAllTeam类型：component [allTeam，member]

@Id
@ManyToOne
@JoinColumn(name = "team_id", referencedColumnName = "teamId")
private Team allTeam;

@Id
@ManyToOne
@JoinColumns({
    @JoinColumn(name = "identifier_AllTeam" ,referencedColumnName ="identifier" ),
    @JoinColumn(name = "connectionType_AllTeam" ,referencedColumnName ="connectionType") 
} )

private Member member;

Answer 1

在@Id之前移除@ManyToOne。更多参考波纹链接
