在我正在研究的示例Spring Boot webapp中,将实体映射到DTO并使用Orika时,我遇到了一个奇怪的ClassCastException.当我尝试在嵌入式Tomcat中部署的应用程序上进行映射时,我得到了异常,但我可以在JUnit测试上下文中完成映射.这是相关的类(它们都非常简单):

JPA实体:

@Entity
public class Position {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String name;
    // getters/setters...
}

DTO:

public class PositionDto {

    private Integer id;
    private String name;
    // getters/setters...
}

休息控制器:

@RestController
public class PositionController {

    @Autowired
    private PositionService positionService;

    @RequestMapping("/position")
    public PositionDto get() {
        final PositionDto positionDto = positionService.getPosition(1);
        return positionDto;
    }
}

服务类:

@Service
public class PositionServiceImpl implements PositionService {

    @Autowired
    private PositionRepository positionRepository;
    @Autowired
    private OrikaBeanMapper mapper;

    @Transactional(readOnly = true)
    @Override …
