java如果类中没有此类字段，如何接收id上的可嵌入对象？

Question

我是spring data jpa的新手。 类Person包含字段集<；'地址>；地址。当我将具有相关地址的对象person保存到数据库时，我对person\u id:joinColumns=@JoinColumn（name=“person\u id”）上的地址使用join。类地址没有字段id或人员id。数据保存正确。如何在AddressRepository中编写方法，使用person_id从db获取地址

@Entity
@NamedQuery(name = "Person.findByPhone",
        query = "select p from Person as p join p.phoneNumbers as pn where pn.number = :number")
@Table(uniqueConstraints={
        @UniqueConstraint(columnNames = {"lastName", "firstName", "patronymic"})
})
public class Person {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private Integer id;

    private String lastName;

    @NotNull
    private String firstName;

    private String patronymic;

    @ElementCollection(fetch = FetchType.EAGER)
    @CollectionTable(name = "person_phone_numbers", joinColumns = @JoinColumn(name = "person_id"))
    private Set<PhoneNumber> phoneNumbers = new HashSet<>();

    @ElementCollection(fetch = FetchType.EAGER)
    @CollectionTable(name = "person_addresses", joinColumns = @JoinColumn(name = "person_id"))
    @AttributeOverrides({
            @AttributeOverride(name = "addressLine1", column = @Column(name = "house_number")),
            @AttributeOverride(name = "addressLine2", column = @Column(name = "street"))
    })
    private Set<Address> addresses = new HashSet<>();

    public Person() {
    }

    public Person(String lastName, String firstName, String patronymic,
                  Set<PhoneNumber> phoneNumbers, Set<Address> addresses) {
        this.lastName = lastName;
        this.firstName = firstName;
        this.patronymic = patronymic;
        this.phoneNumbers = phoneNumbers;
        this.addresses = addresses;

    }
getters and setters
}

接口地址存储库（它给我一个错误org.springframework.beans.factory.BeanCreationException:创建名为'requestMappingHandlerAdapter'的bean时出错）：

public interface AddressRepository extends JpaRepository<Address, Long> {

   Address findByPersonId(Integer person_id);
}
