Проблема с интеграционным тестом Spring, включающим объект с отложенными коллекциями

#spring-test #spring-mvc-test #spring-security-test

#spring-test #spring-mvc-test #spring-security-test

Вопрос:

Я экспериментирую с новой платформой тестирования безопасности Spring. У меня есть тест, который включает возврат объекта JPA с отложенными коллекциями.

Следующий тест заканчивается ошибкой, поскольку одна из отложенных коллекций.

 @RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ActiveProfiles({ Profiles.TEST })
@ContextConfiguration(classes = { FullSecurityTestConfiguration.class, FullIntegrationTestConfiguration.class, BaseTestConfiguration.class, WebMvcConfiguration.class,
        EnableHelperComponents.class })
@TestExecutionListeners(listeners = { ServletTestExecutionListener.class, DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class, WithSecurityContextTestExcecutionListener.class })
public class CurriculumPermissionEvaluatorAuthorizationTest {

    @Autowired
    private WebApplicationContext wac;
    private MockMvc mockMvc;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @After
    public void clean() {
        SecurityContextHolder.clearContext();
    }
    @Test
    @WithUserDetails("balteo@yahoo.fr")
    public void shouldAllowCurriculumRetrieval() throws Exception {
        mockMvc.perform(get("/curriculum/findCurriculumById").param("id", "1")//
                .contentType(MediaType.APPLICATION_JSON)//
                .header("X-Ajax", "true"))//
                .andDo(print())//
                .andExpect(status().isOk());//
    }

Что я получаю неправильно в моей тестовой настройке? Почему JPA entity manager закрывается слишком рано? Как я могу обойти эту проблему?

правка 1:

Метод из контроллера:

 @RequestMapping(value = "/findCurriculumById", method = RequestMethod.GET, produces = "application/json")
    @ResponseBody
    public Curriculum findCurriculumById(@RequestParam Long id) {
        return curriculumService.findCurriculum(id);
    }

Метод из сервиса:

 @Override
    @PreAuthorize("isAuthenticated() AND hasPermission(#curriculumId, 'curriculumByIdOwnerPermission')")
    @Cacheable(value = CacheConfiguration.DATABASE_CACHE_NAME, key = "'curriculum.Id:'   #curriculumId")
    public Curriculum findCurriculum(Long curriculumId) {
        return curriculumRepository.findOne(curriculumId);
    }

правка 2:

Я понял, что тест на самом деле ошибочный, хотя я прокомментировал метод тестирования с помощью @Transactional следующим образом:

 @Test
@WithUserDetails("balteo@yahoo.fr")
@Transactional
public void shouldAllowCurriculumRetrieval() throws Exception {
    mockMvc.perform(get("/curriculum/findCurriculumById").param("id", "1")//
            .contentType(MediaType.APPLICATION_JSON)//
            .header("X-Ajax", "true"))//
            .andDo(print())//
            .andExpect(status().isOk());//
}

Вот соответствующая часть учебного плана:

 @Entity
public class Curriculum {

    @OneToMany(cascade = CascadeType.ALL, mappedBy = "curriculum")
    private Set<WorkExperience> workExperiences;

Ответ №1:

Ваш метод тестирования не транзакционный.

Вам нужно аннотировать либо CurriculumPermissionEvaluatorAuthorizationTest , либо shouldAllowCurriculumRetrieval() с @Transactional помощью.

Комментарии:

1. Сэм: Мне очень жаль: я только что понял, что аннотирование метода с помощью @Transactional на самом деле не решило проблему… Моя ошибка в том, что я изначально пометил ответ как принятый…

2. Как выглядит конфигурация транзакции для curriculumService.findCurriculum(id) ? Аннотирован ли метод, класс или интерфейс с помощью @Transactional , и если да, то на какое propagation значение они установлены?

3. findCurriculum @Transactional соответствует следующему объявлению Roo ITD: declare @type: CurriculumServiceImpl: @Transactional; Распространение должно быть по умолчанию, т. Е. обязательным.

4. Насколько я вижу, ваш метод тестирования все равно должен быть @Transactional ; в противном случае ваша транзакция (и, следовательно, ваш сеанс) завершается, когда завершается вызов curriculumService.findCurriculum(id) .

5. Если вы не можете заставить его работать, убедившись, что тест является транзакционным , было бы проще помочь вам, если вы создадите уменьшенный тестовый проект , который демонстрирует проблему.
