ModelMapper-未能将org.hibernate.collection.internal.PersistentBag转换为java.util.ArrayList

ModelMapper配置应该是什么样子

编译组：“org.modelmapper”，名称：“modelmapper”，版本：“2.3.8”

目前我有：

 modelMapper = new ModelMapper();
            modelMapper.getConfiguration()
                    .setMatchingStrategy(MatchingStrategies.STANDARD)
                    .setFieldMatchingEnabled(true)
                    .setFieldAccessLevel(Configuration.AccessLevel.PRIVATE);

我的实体

@OneToMany(mappedBy = "employee", cascade = CascadeType.ALL, orphanRemoval = true)
private List<Phones> phones = new ArrayList<>();

我想要的DTO：

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor(force = true)
public class EmployeeDTO {

@Singular
private final List<PhoneDTO> phones;

}

我得到：

转换器org.modelmapper.internal.Converter。MergingCollectionConverter@969b4391无法将org.hibernate.collection.internal.PersistentBag转换为java.util.ArrayList

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor(force = true)
public class EmployeeDTO {

@Singular
private final List<PhoneDTO> phones;

}

        EmployeeDTO.EmployeeDTOBuilder employeeDTOBuilder 
= ObjectMapperUtils.map(employee, EmployeeDTO.employeeDTOBuilder.class);
