Dozer: org.dozer.MappingProcessor: ошибка отображения поля

/ 28 марта 2020

Я просто использовал аннотацию dozer v для отображения между классами и DTO. у меня есть некоторые отношения oneToMany и ManyToOne, тогда, когда я пытаюсь получить список клиентов после добавления команды к клиенту, я думаю, что поле команды отображается неправильно в классе клиента, я получаю следующую ошибку:

это часть моего кода: мои классы 

    @Setter
    @Getter
    @Entity
    @AllArgsConstructor
    @NoArgsConstructor
    public class Command implements Serializable {

        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long id;
        @Mapping("commandNumber")
        private String commandNumber;
        @Mapping("commandName")
        private String commandName;
        @Mapping("commandType")
        private String commandType;
        @Mapping("customer")
        @ManyToOne
        @JoinColumn(name = "customer_id")
        private Customer customer;


    }
--------------------

@Setter
@Getter
@Entity
@NoArgsConstructor
@AllArgsConstructor
public class Customer implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Mapping("id")
    private Long id;
    @Mapping("firstName")
    private String firstName;
    @Mapping("lastName")
    private String lastName;
    @Mapping("phoneNumber")
    private String phoneNumber;
    @Mapping("address")
    private String address;

    @Mapping("commands")
    @OneToMany(mappedBy = "customer" ,fetch = FetchType.LAZY)
    private Set<Command> commands;
}

классы DTO 

@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
public class CommandDto {

    private Long id;
    private String commandNumber;
    private String commandName;
    private String commandType;
    private CustomerDto customer;
}
--------------------

@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
public class CustomerDto {

    private Long id;
    private String firstName;
    private String lastName;
    private String phoneNumber;
    private String address;
    private Set<CommandDto> commands;

}

класс DozerMapper: 

@Component
public class CommandMapper {
    Mapper mapper = new DozerBeanMapper();

    public Command toEntity(CommandDto commandDto) {
        return mapper.map(commandDto, Command.class);
    }

    public CommandDto toDto(Command command) {
        return mapper.map(command, CommandDto.class);
    }

    public List<Command> mapListObjectDTOtoListObject(List<CommandDto> commandDtos) {
        List<Command> commands = new ArrayList<>();
        for (CommandDto commandDto : commandDtos) {
            commands.add(mapper.map(commandDto,Command.class));
        }
        return commands;
    }
    public List<CommandDto> mapListObjecttoListObjectDto(List<Command> commands) {
        List<CommandDto> commandDtos = new ArrayList<>();
        for (Command command : commands) {
            commandDtos.add(mapper.map(command,CommandDto.class));
        }
        return commandDtos;
    }

}

------------

@Component
public class CustomerMapper {
    Mapper mapper = new DozerBeanMapper();

    public Customer toEntity(CustomerDto customerDto) {
        return mapper.map(customerDto, Customer.class);
    }

    public CustomerDto toDto(Customer customer) {
        return mapper.map(customer, CustomerDto.class);
    }

    public List<Customer> mapListObjectDTOtoListObject(List<CustomerDto> customerDtos) {
        List<Customer> customers = new ArrayList<>();
        for (CustomerDto customerDto : customerDtos) {
            customers.add(mapper.map(customerDto,Customer.class));
        }
        return customers;
    }
    public List<CustomerDto> mapListObjecttoListObjectDto(List<Customer> customers) {
        List<CustomerDto> customersDtos = new ArrayList<>();
        for (Customer customer : customers) {
            customersDtos.add(mapper.map(customer,CustomerDto.class));
        }
        return customersDtos;
    }

}

Есть идеи?
