java - 无法从 mapStruct Autowiring Mapper

Question

我无法在测试中从mapstruct Autowiring Mapper。在使用 SpringRunner.class 进行测试时可以，但是当我尝试使用 MockitoJunitRunner 时，这是不可能的。

@Mapper(componentModel = "spring", uses = {})
public interface UserMapper {
    UserMapper MAPPER = Mappers.getMapper(UserMapper.class);

    User mapToUser(UserDto userDto);

    UserDto mapToUserDto(User user);

    List<UserDto> mapToUserDtoList(List<User> userList);
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class nowyTest {
    @Spy
    private UserMapper userMapper;

    private User createUser() {
        return User.builder()
                .firstName("Steve")
                .lastName("Jobs")
                .login("SteveJobs")
                .password("password")
                .role(UserRole.ROLE_ADMIN)
                .build();

    }

    @Test
    public void testMapper() {
        User user = createUser();
        UserDto userDto = userMapper.mapToUserDto(user);

        System.out.println(userDto);
        Assert.assertEquals(userDto.getFirstName(), "Steve");
    }

}

它返回 NPE :(

您是否尝试过包含注释@Import(yourClass)？在这种情况下:

@RunWith(SpringRunner.class)
@SpringBootTest
@Import(UserMapper.class)
public class nowyTest {
   ...
