如何在 table Spring + Hibernate + Spring 安全中填充外键
How to populate foreign key in table Spring + Hibernate + Spring Security
我想举个例子,当用户通过 Spring 安全认证,然后他填写地址表时,我想自动更新用户 table 中的外键列 "adres_id" .请告诉我如何以最流行的方式实现它
我怎么会这样
地址Table:
用户Table:
地址
@Entity
@Table(name="adres")
public class Adres {
@Id
@GeneratedValue(strategy = GenerationType.AUTO )
int id;
@Column(name="country", nullable=false)
private String country;
private String street;
private String postcode;
private String telephone;
private String pesel;
@OneToOne(mappedBy ="adres")
private User user;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
public String getTelephone() {
return telephone;
}
public void setTelephone(String telephone) {
this.telephone = telephone;
}
public String getPesel() {
return pesel;
}
public void setPesel(String pesel) {
this.pesel = pesel;
}
public String getStreet() {
return postcode;
}

}
}
用户
@Entity
@Table(name="users")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO )
int id;
@Column(name="username", nullable=false)
private String username;
private String password;
private String email;
private Boolean enabled;
@OneToOne(cascade = CascadeType.ALL)
private Adres adres;
public Boolean getEnabled() {
return enabled;
}
public void setEnabled(Boolean enabled) {
this.enabled = enabled;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
AdresDAO
@Repository
@Transactional
public class AdresDAOImpl implements AdresDAO{
@Autowired
SessionFactory sessionFactory;
public void addAdres(Adres adres) {
sessionFactory.getCurrentSession().save(adres);
}
public List<Adres> listAdres() {
return sessionFactory.getCurrentSession().createQuery("from Adres order by id").list();
}
public void removeAdres(int id) {
Adres adres = (Adres) sessionFactory.getCurrentSession().load(
Adres.class, id);
if (null != adres) {
sessionFactory.getCurrentSession().delete(adres);
}
}
public Adres getAdres(int id) {
return (Adres)sessionFactory.getCurrentSession().get(Adres.class, id);
}
public void editAdres(Adres adres) {
sessionFactory.getCurrentSession().update(adres);
}
}
地址服务
@Service
public class AdresServiceImpl implements AdresService{
@Autowired
AdresDAO adresDAO;
@Transactional
public void addAdres(Adres adres) {
adresDAO.addAdres(adres);
}
@Transactional
public void editAdres(Adres adres) {
adresDAO.editAdres(adres);
}
@Transactional
public List<Adres> listAdres() {
return adresDAO.listAdres();
}
@Transactional
public void removeAdres(int id) {
adresDAO.removeAdres(id);
}
@Transactional
public Adres getAdres(int id) {
return adresDAO.getAdres(id);
}
}
User
User
和 Address
之间的单向关系,如果 Address
对象不应该知道它的所有者(通常它不知道)。如果 User
有多个 Address
(一对多关系),我更喜欢 Address
table 中的用户 ID。
但是对于你的问题你可以这样设计,
public class User{
...
@OneToOne(CascadeType.REMOVE)//this is for to remove address when user is removed
@JoinColumn(name="HOME_ADDRESS_ID")
private Address address;
...
}
和
public class Address {
@Id
@GeneratedValue(strategy = GenerationType.AUTO )
int id;
@Column(name="country", nullable=false)
private String country;
private String street;
private String postcode;
private String telephone;
private String pesel;
//no user object here
public int getId() {
return id;
}
...
}
