【问题描述】:
我正在尝试使用 Spring、Hibernate 和 MySql 将数据插入数据库。将数据插入数据库时出现以下错误 “Bean 名称‘所有者’的 BindingResult 和普通目标对象都不能用作请求属性”。我尝试了所有可能的解决方案,但无法清除它。
这是我的控制器
@Controller
public class DataOwnerRegController {
@Autowired(required = true)
DataService dataService;
@RequestMapping(value="/DataOwnerReg",method = RequestMethod.POST)
public String getForm(@ModelAttribute("owner") Model model )
{
model.addAttribute("owner", new Owner());
return "DataOwnerReg";
}
@RequestMapping(value = "/DataOwnerReg")
public ModelAndView registeruser(@ModelAttribute("owner") Owner owner, BindingResult result){
ModelAndView modelAndView = new ModelAndView("DataOwnerReg");
dataService.insertRow(owner);
return modelAndView;
}
}

请帮忙。
提前致谢
【问题讨论】:
-
您返回的是
ModelAndView,但模型为空。返回String而不是ModelAndView或正确填充模型。 -
仍然出现同样的错误.. 你能帮帮我吗
-
您的
@ModelAttribute方法参数上有一个@ModelAttribute,请将其删除。我也怀疑这是您的实际控制器,您将如何在 POST 方法上填充模型?恕我直言,应该是 GET,提交是 POST。 -
我已经删除了@ModelAttribute。我应该将其更改为 GET 方法。
-
目前该方法将在提交时调用,而不是在您期望它被调用时调用。
