У меня возникают проблемы при реализации @Reference
в Spring Boot + Spring Data Redis
. Address
- это список в Employee
, и когда я сохранил адреса office
и home
, я ожидал, что данные будут сохранены с Employee
. Но данные не были сохранены и, следовательно, не удалось найти Address
, используя street
.
Employee.java
@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
@RedisHash("employees")
public class Employee {
@Id @Indexed
private String id;
private String firstName;
private String lastName;
@Reference
private List<Address> addresses;
}
Address.java
@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
@RedisHash("address")
public class Address {
@Id
private String id;
@Indexed
private String street;
private String city;
}
Тестовый класс
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class EmployeeAdressTest extends RepositoryTestSupport{
@Autowired private EmployeeRepository employeeRepository;
@Before
public void setUp() throws JsonProcessingException {
Address home = Address.builder().street("ABC Street").city("Pune").build();
Address offc = Address.builder().street("XYZ Street").city("Pune").build();
Employee employee1 = Employee.builder().firstName("Raj").lastName("Kumar").addresses(Arrays.asList(home, offc)).build();
employeeRepository.save(employee1);
List<Employee> employees = employeeRepository.findByAddresses_Street("XYZ Street");
System.out.println("EMPLOYEE = "+employees);
}
@Test
public void test() {
}
}
Spring Doc:
8.8. Persisting References
Marking properties with @Reference allows storing a simple key reference instead of copying values into the hash itself. On loading from Redis, references are resolved automatically and mapped back into the object, as shown in the following example:
Example 30. Sample Property Reference
_class = org.example.Person
id = e2c7dcee-b8cd-4424-883e-736ce564363e
firstname = rand
lastname = al’thor
mother = people:a9d4b3a0-50d3-4538-a2fc-f7fc2581ee56
Reference stores the whole key (keyspace:id) of the referenced object.
