Java 无法插入ItemDetail的列表，即列表<；项目详情>；（对象）通过Hibernate使用SpringMVC导入MySQL数据库

我正在尝试创建一个名为“invoicedto”的表，其中有一个字段，由ItemDetail（POJO对象）的列表组成

我需要澄清以下几点： 1.我们可以在MySQL数据库的字段中插入对象列表吗？ 如果可能的话怎么办？MYSQL中我的列的数据类型应该是什么？ 2.如果我们无法插入列表？是否有其他方法实现此场景

如果您已在下面附上我的代码：

控制器：

@Controller
public class InvoiceController {

@Autowired
InvoiceService invoiceService;

public void setInvoiceService(InvoiceService invoiceService) {
    this.invoiceService=invoiceService;
}


@RequestMapping("/invoice/add")
public ModelAndView addInvoice(){
    Map<String,Object> businessDataMap=new HashMap<>();
    ModelAndView modelAndView=new ModelAndView();
    String invoiceNumber = invoiceService.generateInvoiceNumber();
    businessDataMap.put("invoiceNumber", invoiceNumber);
    modelAndView.addAllObjects(businessDataMap);
    modelAndView.setViewName("add_invoice");
    return modelAndView;
}
}
