：

EMP_PHONE 
================================= 
EMP_ID PHONES_ID PHONE_TYPE 
------ --------- ---------- 
42  1   NULL 


EMPLOYEE 
================================= 
ID 
-- 
42 


PHONE 
================================= 
ID NUM 
-- -------- 
1  867-5309

NULLPHONE_TYPEはファンキーな何かが起こっている私に教えているようだ、とのEclipseLinkはEMPLOYEE.PHONE_TYPE探している方法は、私はそれが関係について考えていると思いますそれ以外の方法ではなくPHONE - >EMPLOYEEから

JPAエンティティは次のように定義されます。携帯電話・マップは一方向である、と電話オブジェクトは（ない私の実際の型が、この単純化した例では、問題を示しています）、複数の従業員で共有しなければならない

次のテストコード

EntityManagerFactory factory = Persistence.createEntityManagerFactory("test"); 
EntityManager em = factory.createEntityManager(); 
Employee employee = new Employee(42); 
// exception will occur with or without phones added to the map 
employee.getPhones().put("home", new Phone(1, "867-5309")); 
em.getTransaction().begin(); 
em.persist(employee); 
em.getTransaction().commit(); 

Query q = em.createQuery("select o from Employee o"); 
q.setHint("javax.persistence.cache.storeMode", "REFRESH"); 
q.getResultList(); // EXCEPTION THROWN HERE

および持続性を使用して

@Entity 
public class Employee { 
    @Id private long id; 

    @OneToMany(cascade=CascadeType.ALL) 
    @JoinTable(name="EMP_PHONE", [email protected](name="EMP_ID")) 
    @MapKeyColumn(name="PHONE_TYPE") 
    private Map<String, Phone> phones = new HashMap<String, Phone>(); 

    public Employee() {} 
    public Employee(long id) { 
     this.id = id; 
    } 
    public long getId() { 
     return id; 
    } 
    public Map<String, Phone> getPhones() { 
     return phones; 
    } 
} 

@Entity 
public class Phone { 
    @Id 
    private long id; 
    private String num; 

    public String getNum() { 
     return num; 
    } 
    public Phone() {} 
    public Phone(String num) { 
     this.num = num; 
    } 
    public Phone(long id, String num) { 
     this.id = id; 
     this.num = num; 
    } 
    public long getId() { 
     return id; 
    } 
}

これはEclipseLinkのバグ364922次のようになります。それは価値がある何のため

An entity with uni-directional OneToMany property and @MapKeyColumn annotation has the correct database tables created, with the mapping table containing a "key column, but persisting an entity only populates the id columns and not the key column. The persist operation does not throw an error, but subsequent queries soon fail with the following error: Exception Description: The field [ORGANIZATION.MAILINGADDRESSES_KEY] in this expression has an invalid table in this context.

、私は、Hibernate/H2を使用してコードをテストし、それが正常に動作します。

UPDATE

私はただのEclipseLinkでこれをテストしました。 MapKeyColumnのテーブルを明示的に設定すると、キーが正しく入力されます。すなわち：

@MapKeyColumn(name="PHONE_TYPE", table="EMP_PHONE")

ありがとうございました！私はそれが私が試していないオプションの1つの組み合わせだと思う;）私が探していたときに私はそのバグを見て欲しい。 –

私は実際のアプリでそれをテストし、それは完全に動作します。もう一度ありがとう –

喜んでそれが助けた。私はJPAの実装に関しては分かりにくい問題に直面しています。 – pwrex
