【解决方案1】：

您的映射无效

@OneToMany(mappedBy = "sellerDO", targetEntity=StoreDO.class, cascade = CascadeType.ALL)
private StoreDO storeDO;

应该是

@OneToMany(mappedBy = "sellerDO", targetEntity=StoreDO.class, cascade = CascadeType.ALL)
private List<StoreDO> storeDO;

@OneToMany(mappedBy = "sellerDO", targetEntity=StoreDO.class, cascade = CascadeType.ALL)
private Set<StoreDO> storeDO;
