개체 필드가 ​​AddressForm의 유효성을 검사하지 않는 이유는 무엇입니까?

addresses멤버 UserAddressesForm@Valid주석 으로 장식해야합니다 . JSR 303 : Bean Validation 의 섹션 3.1.3 및 3.5.1을 참조하십시오 . Annotated method를 사용하여 JSR 303 Bean Validation을 활성화하는 표준 방법이 있습니까? 라는 질문에 대한 답변에서 설명했듯이 JSR 303에 따른 @Valid주석 의 실제 사용입니다 .

예제 코드 편집 : Hibernate Validator- Object Graph . (자동차 탑승객 목록)


Adding to @Ritesh answer, @Valid constraint will instruct the Bean Validator to delve to the type of its applied property and validate all constraints found there. Answer with code to your question, the validator, when seeing a @Valid constraint on addresses property, will explore the AddressForm class and validate all JSR 303 constraints found inside, as follows:

public class UserAddressesForm {

    @NotEmpty
    private String firstName;

    @NotEmpty
    private String lastName;

    @Valid
    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

In the class UserAddressesForm add the following lines

@Valid
private List<AddressForm> addresses;

Working solution.

public class UserAddressesForm {

    @NotEmpty(message="firstName is required")
    private String firstName;

    @NotEmpty(message="lastNameis required")
    private String lastName;

    @NotNull(message="addresses attributes are required")
    @Valid
    private List<AddressForm> addresses;

...
setters and getters 

public class AddressForm {

    @NotEmpty(message="customNameis required")
    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
