错误原因：   unique = false ,我写了 true ,这里面的 false 是非唯一外键的意思 

@JsonIgnore
	@JSONField(serialize = false) 
	@ManyToOne(cascade = CascadeType. REFRESH, targetEntity = Province.class  , fetch = FetchType.EAGER)   
    @JoinColumn(name = "province_id",  unique = false, nullable = false, updatable = false ,insertable = true )  
    @NotFound(action=NotFoundAction.IGNORE)  
    @Cascade(value = { org.hibernate.annotations.CascadeType.SAVE_UPDATE })  
	private Province parentProvince;
