Spring集成測試問題涉及一個懶惰集合的實體

我正在試驗新的Spring Security測試框架。我有一個測試，涉及返回一個JPA實體與懶惰的集合。Spring集成測試問題涉及一個懶惰集合的實體

由於其中一個懶惰集合，下列測試最終出錯。

@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("[email protected]") 
    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());// 
    }

以下是錯誤消息：

什麼我得到錯誤的，我的測試設置？爲什麼JPA實體經理太早關閉？我怎樣才能繞過這個問題？

編輯1：

從控制器方法：

@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); 
    }

編輯2：

我意識到

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

從服務方法測試實際上是錯誤的，即使我已經標註了@Transactional的測試方法如下：

@Test 
@WithUserDetails("[email protected]") 
@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());// 
}

這裏是課程的有關部分：

@Entity 
public class Curriculum { 

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

您的測試方法是而不是交易。

您需要註釋CurriculumPermissionEvaluatorAuthorizationTest或shouldAllowCurriculumRetrieval()與@Transactional。

Sam：我很抱歉：我剛剛意識到用@Transactional註釋該方法實際上並沒有解決問題......我的錯誤是將答案標記爲首先被接受...... – balteo

我編輯過我的帖子有更多的信息。 – balteo

「curriculumService.findCurriculum（id）」的交易配置是什麼樣的？方法，類或接口是否用'@Transactional'註解，如果是的話，那麼'propagation'設置爲什麼？ –
