我的主要课程是
public class UserAddressesForm {
@NotEmpty
private String firstName;
@NotEmpty
private String lastName;
private List<AddressForm> addresses;
...
setters and getters
public class AddressForm {
@NotEmpty
private String customName;
@NotEmpty
private String city;
@NotEmpty
private String streetAn;
@NotEmpty
private String streetHn;
@NotEmpty
private String addressCountry;
@NotEmpty
private String postCode;
...
setters and getters
控制器
@RequestMapping(value = "/up", method = RequestMethod.POST)
public String completeForm(@Valid @ModelAttribute("userAddressesForm") UserAddressesForm userAddressesForm,
BindingResult result, HttpServletRequest req)
...

为什么对象字段未通过AddressForm验证?
请帮忙。
最佳答案
您需要使用addresses
注释装饰UserAddressesForm
的@Valid
成员。请参见JSR 303: Bean Validation的3.1.3和3.5.1节。正如我在对问题Is there a standard way to enable JSR 303 Bean Validation using annotated method的回答中所解释的那样,这实际上是根据JSR 303使用的@Valid
批注。
编辑
示例代码:Hibernate Validator- Object Graph。 (汽车乘客名单)
从Hibernate Validator 6参考文档编辑:
在6之前的版本中,Hibernate Validator支持对容器元素子集的级联验证,并且它是在容器级别实现的(例如,您可以使用@Valid private List<Person>
为Person
启用级联验证)。
仍然支持,但不建议这样做。请使用容器
元素级@Valid
注释,因为它更具表现力。
例:
public class Car {
private List<@NotNull @Valid Person> passengers = new ArrayList<Person>();
private Map<@Valid Part, List<@Valid Manufacturer>> partManufacturers = new HashMap<>();
//...
}
另请参阅Bean Validation 2.0/Jakarta Bean Validation中的新增功能。
