JPA 오라클 NoSQL의 DB에 일대 다 관계 - 삽입, OracleNoSQLRecord 예외

Question

내가 (는 EclipseLink API를 사용하여) 오라클 NoSQL에 DB와 JPA작업입니다.

필자에게는 일대 다 관계가있는 Person 및 Address 클래스가 두 가지 있습니다. 아래의 코드 :

@Entity 
@NoSql (dataFormat = DataFormatType.MAPPED) 
public class Person implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @GeneratedValue 
    @Field(name = "_id") 
    private String id; 

    private String firstName; 

    private String lastName; 

    @OneToMany(mappedBy = "person", cascade = CascadeType.ALL, fetch = FetchType.LAZY) 
    private List<Address> addresses = new ArrayList<>(); 

그리고

@Entity 
@NoSql (dataFormat = DataFormatType.MAPPED) 
public class Address implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @GeneratedValue 
    @Field(name = "_id") 
    private String id; 

    private String street; 

    private String city; 

    private String country; 

    private Integer pincode; 

    @JoinField(name = "PERSON_ID", referencedFieldName = "_id") 
    @ManyToOne(optional = false, fetch = FetchType.LAZY) 
    private Person person; 

내 주요 기능은 다음과 같습니다 :

EntityManagerFactory emf = Persistence.createEntityManagerFactory("TestPU"); 
    EntityManager em = emf.createEntityManager(); 
    EntityTransaction tx = em.getTransaction(); 

    try { 
     tx.begin(); 

     Person p1 = new Person(); 
     p1.setFirstName("fn"); 
     p1.setLastName("ln"); 

     List<Address> addrList = new ArrayList<>(); 

     Address addr1 = new Address(); 
     addr1.setStreet("str"); 
     addr1.setCity("City"); 
     addr1.setCountry("Ctry"); 
     addr1.setPincode(123456); 
     addrList.add(addr1); 

     Address addr2 = new Address(); 
     addr2.setStreet("str2"); 
     addr2.setCity("City2"); 
     addr2.setCountry("Ctry2"); 
     addr2.setPincode(223456); 
     addrList.add(addr2); 

     p1.setAddresses(addrList);  
     em.persist(p1); 
     tx.commit(); 

내의 persistence.xml은 다음과 같습니다 :

<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> 
    <persistence-unit name="TestPU" transaction-type="RESOURCE_LOCAL"> 
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> 
     <exclude-unlisted-classes>false</exclude-unlisted-classes> 
    <properties> 
     <property name="eclipselink.target-database" value="org.eclipse.persistence.nosql.adapters.nosql.OracleNoSQLPlatform"/> 
     <property name="eclipselink.nosql.connection-spec" value="org.eclipse.persistence.nosql.adapters.nosql.OracleNoSQLConnectionSpec"/> 
     <property name="eclipselink.nosql.property.nosql.host" value="dockerHost:5002"/> 
     <property name="eclipselink.nosql.property.nosql.store" value="camiantDBstore"/> 
     <property name="eclipselink.logging.level" value="FINEST"/> 
    </properties> 
    </persistence-unit> 
</persistence> 

때 내 주요 방법을 실행하고 전자 xception가 발생합니다 :

그러나, 나는 @OneToMany 관계 주석 대신에 포함 가능한 주석 @ 임베디드/@을 사용하고 때 데이터를 동일한 데이터를 삽입 할 수 있어요.

도움을 주시면 감사하겠습니다.

Answer 1

@NoSql (DATAFORMAT = DataFormatType.XML)

대신

@NoSql (DATAFORMAT = DataFormatType.MAPPED)

문제가 해결 사용.
