我正在尝试通过使用fetchtype.lazy为我们的基金实体实现延迟加载，该基金实体与fundalternateid实体具有一对多关系
尝试访问基金终结点时，出现以下错误：
原因：org.hibernate.lazyinitializationexception:未能延迟初始化角色集合：com.example.model.fund.fundalternateids，无法初始化代理-无会话
jsonmappingexception:未能延迟初始化角色的集合：com.example.model.model.fundalternateids，无法初始化代理-无会话（通过引用链：java.util.collections$unmodifiablerandomaccesslist[0]->com.example.model.model.fundalternateids[“fundalternateids”]）；在com.fasterxml.jackson.databind.jsonmappingexception.wrapwithpath（jsonmappingexception）上。java:397) ;
以下是我的项目文件：
基金实体

@Entity(name="fund")
@Table(name="mv_fund_info")
@Getter
@Setter
public class Fund implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @Column(name = "fund_port_id")
    private String fundPortId;

    @Column(name = "fund_full_name")
    private String fundFullName;

    @Column(name = "fund_short_name")
    private String fundShortName;

    @OneToMany(
            mappedBy = "associatedFund",
            fetch = FetchType.LAZY
    )
    @JsonManagedReference
    private List<FundAlternateId> fundAlternateIds;
}

fundalternateid类

@Entity(name="fundAlternateId")
@Table(name="mv_fund_alternate_id")
@Getter
@Setter
public class FundAlternateId implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @JsonIgnore
    @Column(name="alternate_id_ins_id")
    private Long alternateIdInsId;

    @Column(name="alternate_id_value")
    @Text
    private String alternateIdValue;

    @Column(name="alternate_id_type")
    @Text
    private String alternateIdType;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name="fund_port_id")
    @JsonBackReference
    private Fund associatedFund;
}

休息控制器

@GET
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public Response getPublicFundAttributes() {
  List<Fund> publicFunds = fundService.getAllPublicFunds(offset,limit, sortBy);
  return Response.status(Status.OK).type(MediaType.APPLICATION_JSON).entity(publicFunds).build();
}

基金服务

@Service
@Transactional("myTransactionManager")
public class FundServiceImpl implements FundService {

    @Autowired
    FundDao fundDao;

    @Override
    public List<Fund> getAllPublicFunds(Integer pageNo, Integer pageSize, String sortBy) {
        List<Fund> fundList = fundDao.getAllPublicFunds(pageNo, pageSize, sortBy);
        return fundList;
    }
}

本道
@名为（“funddao”）的公共类funddaoimpl实现funddao{

@Autowired
@Qualifier("fundRepository")
FundRepository fundRepository;

@Override
public List<Fund> getAllPublicFunds() {
    List<Fund> pagedResult = fundRepository.findAll();
    return pagedResult;
}

}
基金存储库

@Repository("fundRepository")
public interface FundRepository extends PagingAndSortingRepository<Fund, String> {}
