使用Hibernate Validator时另一个类内部的类的批注

Question

我使用Hibernate Validator API对一个名为Supplier_Registration的表进行服务器端验证。对应的Java类如下所示。它的一个成员是另一个名为Address的类。为了也验证Address类的成员，我需要对Address使用什么注释？提前谢谢你。

public class Registration implements Serializable {
    private static final long serialVersionUID = 3380401999460628270L;
    private static final String EMAIL_PATTERN =
            "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
            + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

    @NotNull(message="{legalName_notnull}")
    @Size(min=1, max=255, message="{legalName_not_to_exceed}")

    private String legalName;

    @NotNull(message="{adminFirstName_notnull}")
    @Size(min=1, max=40, message="{adminFirstName_not_to_exceed}")
    private String adminFirstName;


    @NotNull(message="{adminLastName_notnull}")
    @Size(min=1, max=40, message="{adminLastName_not_to_exceed}")
    private String adminLastName;

    @NotNull(message="{adminEmail_notnull}")
    @Size(min=1, max=255, message="{adminEmail_not_to_exceed}")
    @Pattern(regexp=EMAIL_PATTERN, message="{adminEmail_not_valid}")
    private String adminEmail;

    @NotNull(message="{reEnterEmail_notnull}")
    @Size(min=1, max=255, message="{reEnterEmail_not_to_exceed}")
    @Pattern(regexp=EMAIL_PATTERN, message="{reEnterEmail_not_valid}")

    private String reEnterEmail;

    @NotNull(message="{phoneCountryNumber_notnull}")
    @Size(min=1, max=5, message="{phoneCountryNumber_not_to_exceed}")
    private String phoneCountryNbr;

    @NotNull(message="{phoneNumber_notnull}")
    @Size(min=1, max=18, message="{phoneNumber_not_to_exceed}")
    private String phoneNumber;

    @NotNull(message="{dunsNumber_notnull}")
    @Size(min=1, max=9, message="{dunsNumber_not_to_exceed}")
    private String dunsNumber;

    private Address address;

您要执行的这种验证称为级联验证。要验证address，您需要在address属性上使用@Valid注释。此外，如果address是必填的(即如果该字段不能为空)，您也可以使用@NotNull。所以你会得到类似这样的东西：

public class Registration implements Serializable {
    // all other properties ...

    @Valid // this one is requred if you want address constraints to be validated
    @NotNull // this one is optional - use it in case if address is a mandatory field
    private Address address;
}
