我正在试验新的 Spring Security Test 框架。我有一个涉及返回带有惰性集合的 JPA 实体的测试。
由于惰性集合之一，以下测试以错误告终。
@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());//
}
这是错误消息：

我在测试设置中遇到了什么问题？为什么过早关闭 JPA 实体管理器？我该如何规避这个问题？
编辑1：
来自控制器的方法：
@RequestMapping(value = "/findCurriculumById", method = RequestMethod.GET, produces = "application/json")
@ResponseBody
public Curriculum findCurriculumById(@RequestParam Long id) {
return curriculumService.findCurriculum(id);
}
服务方法：
@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);
}

我意识到测试实际上是错误的，即使我已经用@Transactional如下注释测试方法：
@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());//
}
