Question

我是hibernate＆amp;的新手。 spring，我想知道如何使用hibernate验证器来映射实体类，例如：如果我有以下实体类，它们之间有一对一的关系。如何使用hibernate验证器的@NotNull等注释来验证两个实体的以下字段：＆＃34; personName，personPhone，personEmail，addressLine1，addressLine2，city，state，＆amp; zipCode＆＃34;。

@Entity
@Table ( name = "person" )
public class FacilityModel {

    @Id
    @GeneratedValue ( strategy = GenerationType.IDENTITY )
    @Column ( name = "pers_id" )
    private int persId;

    @Column ( name = "pers_name" )  
    private String personName;

    @OneToOne ( cascade = CascadeType.ALL )
    @JoinColumn ( name = "pers_Addr_Id" )
    private AddressModel address;

    @Column ( name = "pers_phone_no" )
    private String personPhone;

    @Column ( name = "pers_email" )
    private String personEmail;

和

@Entity
@Table ( name = "address" )
public class AddressModel {

    @Id
    @GeneratedValue ( strategy = GenerationType.IDENTITY )
    @Column ( name = "addr_id" )
    private int addrId;

    @Column ( name = "addr_address_line1" )
    private String addrLine1;

    @Column ( name = "addr_address_line2" )
    private String addrLine2;

    @Column ( name = "addr_city" )
    private String city;

    @Column ( name = "addr_state" )
    private String state;

    @Column ( name = "addr_country" )
    private String country;

    @Column ( name = "addr_zip_code" )
    private String zipCode;

此外，我是否需要在控制器中包含除@Valid注释和BindingResult之外的任何其他代码。

请任何人帮助我。

您只需要在字段上添加要验证的注释，然后在保存之前休眠将检查您的值是否正确。

如果在控制器中添加注释@Valid，您还可以看到您拥有的对象无法保存。
