JPA: Сущности не получают сохранялось

Question

Рассмотрим

@Entity 
public class User { 
    @Id 
    private String id; 
    private String firstName; 
    private String lastName; 
    private String nickName; 
    @ElementCollection 
    private final List<String> emails = new ArrayList<>(); 
    @OneToMany(mappedBy = "user", cascade = CascadeType.ALL) 
    private final List<Address> addresses = new ArrayList<>(); 
    @OneToMany 
    private final List<Phone> phones = new ArrayList<>(); 

    public User(@Nonnull final String firstName, @Nonnull final String lastName) { 
     id = UUID.randomUUID().toString(); 
     this.firstName = firstName; 
     this.lastName = lastName; 
    } 

    public User() { 
     // required by JPA 
    } 

    public String getId() { 
     return id; 
    } 

    @Nonnull 
    public String getFirstName() { 
     return firstName; 
    } 

    @Nonnull 
    public String getLastName() { 
     return lastName; 
    } 

    @Nonnull 
    public String getNickName() { 
     return nickName; 
    } 

    public void setNickName(@Nonnull final String nickName) { 
     this.nickName = nickName; 
    } 

    @Nonnull 
    public List<String> getEmails() { 
     return Collections.unmodifiableList(emails); 
    } 

    @Nonnull 
    public List<Address> getAddresses() { 
     return Collections.unmodifiableList(addresses); 
    } 

    @Nonnull 
    public List<Phone> getPhones() { 
     return Collections.unmodifiableList(phones); 
    } 

    public void addAddress(@Nonnull final Address address) { 
     addresses.add(address); 
    } 

    public void addPhone(@Nonnull final Phone phone) { 
     phones.add(phone); 
    } 

    public void addEmail(@Nonnull final String email) { 
     emails.add(email); 
    } 

    // likewise remove address, phones, emails could be added 
} 

и

@Entity 
public class Address { 
    @Id 
    private String id; 
    private String streetName; 
    private String additionalStreetName; 
    private String city; 
    private String state; 
    private int zip; 
    private String country; 
    private AddressType addressType; 
    @ManyToOne 
    private User user; 

    public Address(@Nonnull final String streetName, @Nullable final String additionalStreetName, 
        @Nonnull final String city, @Nonnull final String state, int zip, 
        @Nonnull final String country) { 
     this(streetName, additionalStreetName, city, state, zip, country, AddressType.HOME); 
    } 

    public Address(@Nonnull final String streetName, @Nullable final String additionalStreetName, 
        @Nonnull final String city, @Nonnull final String state, int zip, 
        @Nonnull final String country, @Nonnull final AddressType addressType) { 
     id = UUID.randomUUID().toString(); 
     this.streetName = streetName; 
     this.additionalStreetName = additionalStreetName; 
     this.city = city; 
     this.state = state; 
     this.zip = zip; 
     this.country = country; 
     this.addressType = addressType; 
    } 

    public Address() { 
     // required by JPA 
    } 

    @Nonnull 
    public String getId() { 
     return id; 
    } 

    @Nonnull 
    public String getStreetName() { 
     return streetName; 
    } 

    @Nullable 
    public String getAdditionalStreetName() { 
     return additionalStreetName; 
    } 

    @Nonnull 
    public String getCity() { 
     return city; 
    } 

    @Nonnull 
    public String getState() { 
     return state; 
    } 

    public int getZip() { 
     return zip; 
    } 

    @Nonnull 
    public String getCountry() { 
     return country; 
    } 

    @Nonnull 
    public AddressType getAddressType() { 
     return addressType; 
    } 

    @Override 
    public String toString() { 
     return "Address{" + 
       "id='" + id + '\'' + 
       ", streetName='" + streetName + '\'' + 
       ", additionalStreetName='" + additionalStreetName + '\'' + 
       ", city='" + city + '\'' + 
       ", state='" + state + '\'' + 
       ", zip=" + zip + 
       ", country='" + country + '\'' + 
       ", addressType=" + addressType + 
       '}'; 
    } 

    public User getUser() { 
     return user; 
    } 

    public void setUser(final User user) { 
     this.user = user; 
    } 
} 

Когда я запускаю мой тест

@Test 
public void testAddUserWithAddress() { 
    final User user; 
    { 
     user = new User("Steve", "Jobs"); 
     Address address1 = new Address("1 Infinite Loop", null, "Cupertino", "California", 94105, "USA"); 
     Address address2 = new Address("2855 Stevens Creek Blvd", "#1025", "Santa Clara", "California", 95050, "USA"); 
     user.addAddress(address1); 
     user.addAddress(address2); 
     crudService.create(user); 
     jpaRule.changeTransaction(); 
    } 
    { 
     final User userInDb = crudService.find(user.getId(), User.class); 
     assertNotNull(userInDb); 
     assertEquals("Two address not present", 2, userInDb.getAddresses().size()); 
     assertEquals(user, userInDb); 
    } 
} 

я получаю обратно следующие

java.lang.AssertionError: Two address not present 
Expected :2 
Actual :0

Я не уверен, почему это не сохраняется, что я делаю неправильно?

Answer 1

У вас отсутствует ссылка между адресом и пользователем?

address1.setUser(user); 
address2.setUser(user); 

Как вы применили crudService.create (user)?
