尝试使用 java spring boot、hibernate 和 thmyeleaf

Question

我已经构建了我的控制器、客户端和地址类（模型）以及用于索引和添加的模板。当我尝试测试验证时，spring 返回：出现意外错误（类型=内部服务器错误，状态=500）。在组 [javax.validation.groups.Default, ] 约束违规列表期间，类 [com.pooltracker.models.Address] 的验证失败：[ ConstraintViolationImpl{interpolatedMessage='Invalid', propertyPath=zipCode, rootBeanClass=class com .pooltracker.models.Address, messageTemplate='Invalid'} ConstraintViolationImpl{interpolatedMessage='may not be null', propertyPath=state, rootBeanClass=class com.pooltracker.models.Address, messageTemplate='{javax.validation.constraints.NotNull .message}'} ConstraintViolationImpl{interpolatedMessage='不能为空', propertyPath=street, rootBeanClass=class com.pooltracker.models.Address, messageTemplate='不能为空'我了解到 hibernate 无法处理验证地址类。我偶然发现了 bean 验证的主题。我对此很陌生，并试图找到解决我的问题的最佳方法，而不会在目前的兔子洞中走得太远。下面是我的控制器和模型。@Controller@RequestMapping("clients")public class ClientController {    @Autowired    private ClientDao clientDao;    @Autowired    private AddressDao addressDao;    @RequestMapping(value = "")    public String index(Model model) {                model.addAttribute("clients", clientDao.findAll());        model.addAttribute("title", "My Clients");                return "clients/index";    }    @RequestMapping(value = "add", method = RequestMethod.GET)    public String displayAddClientForm(Model model) {                model.addAttribute("title", "Add Client");        model.addAttribute(new Client());        return "clients/add";    }    @RequestMapping(value = "add", method = RequestMethod.POST)    public String processAddClientForm(@ModelAttribute @Valid Client newClient,                                       Errors errors, Model model) {         if (errors.hasErrors()) {            model.addAttribute("title", "Add Client");            model.addAttribute("client", newClient);            return "clients/add";        }                clientDao.save(newClient);        return "redirect:";    }}
