尝试使用 java spring boot、hibernate 和 thmyeleaf 来抵抗 MAMP，但在验证时遇到

Question

我已经构建了我的控制器、客户端和地址类(模型(以及模板来索引和添加。 当我尝试测试验证时，弹簧返回：

出现意外错误(类型=内部服务器错误， 状态 = 500(。类验证失败 [com.pooltracker.models.Address] 在组的持久时间内 [javax.validation.groups.Default， ]约束冲突列表：[ ConstraintViolationImpl{interpolatedMessage='Invalid'， 属性路径=邮政编码，根豆类=类 com.pooltracker.models.Address， messageTemplate='Invalid'} ConstraintViolationImpl{interpolatedMessage='may not null'， 属性路径=状态，根豆类=类 com.pooltracker.models.address， messageTemplate='{javax.validation.constraints.NotNull.message}'} ConstraintViolationImpl{interpolatedMessage='Can'不能为空'， 属性路径=街道，根豆类=类 com.pooltracker.models.Address， messageTemplate='不能为空'} ConstraintViolationImpl{interpolatedMessage='Can'不能为空'， propertyPath=city， rootBeanClass=class com.pooltracker.models.Address， 消息模板='不能为空'} ]

我了解到休眠无法处理验证地址类。我偶然发现了 bean 验证的话题。我是新手，并试图找到解决问题的最佳方法，而目前不会走得太远。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:";
}
}

Client实体：

@Entity
@Table(name = "client")
public class Client {
@Id
@GeneratedValue
@Column(name = "client_id")
private int id;
@NotNull
@Size(min=1, message = "Client must have a first name")
@Column(name = "first_name")
private String firstName;
@NotNull
@Size(min=1, message = "Client must have a last name")
@Column(name = "last_name")
private String lastName;
@OneToOne(cascade = CascadeType.ALL,
fetch = FetchType.EAGER, optional = false)
@JoinColumn(name = "address_id")
private Address address;
@NotNull
@Size(min=10, max=10, message = "Must be 10 digits only")
private String phone;
// setters/getters
}

Address实体：

@Entity
@Table(name = "address")
public class Address {
@Id
@GeneratedValue
@Column(name = "address_id")
private int id;
@NotNull
@Size(min=1, message = "Can not be empty")
@Column(name = "street")
private String street;
@NotNull
@Size(min=1, message = "Can not be empty")
@Column(name = "city")
private String city;
@NotNull
@Enumerated(EnumType.STRING)
@Column(name = "state")
private State state;
@NotNull
@Size(min=5, max=5, message = "Invalid")
@Column(name = "zip_code")
private String zipCode;
@OneToOne(mappedBy = "address" , fetch = FetchType.EAGER)
//@JoinColumn(name = "client_id")
public Client client;
// setters and getters
}

Answer 1

在Client类中，将@Valid添加到address字段：

@Valid
@OneToOne(cascade = CascadeType.ALL, 
fetch = FetchType.EAGER, 
optional = false)
@JoinColumn(name = "address_id")
private Address address;

@Validjavadoc 说：

public @interface Valid

标记属性、方法参数或方法返回类型 验证级联。
