我正在使用 spring boot 1.3 开发一个 spring 应用程序
我有一个 MVC 请求处理程序，如下所示：
@RequestMapping(method = PUT, path = "/{categoryId}")
public String update(@Valid @ModelAttribute("category") Category category, BindingResult result, @GetAttribute("currentStore") Store store, Model model, RedirectAttributes ra) {
if (result.hasErrors()) {
model.addAttribute("categories", categoryService.activeCategories(store));
return EDIT_VIEW_NAME;
} else {
categoryService.update(category);
ra.addFlashAttribute("info", "Category updated successfully!");
return redirectTo(categoryUrls.indexPath());
}
}
这是它的集成测试
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(EstoreApplication.class)
@WebIntegrationTest
@Transactional
public class CategoriesControllerIntegrationTests {
@Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
@Test
@WithFactoryUser(roles = "admin")
public void testUpdateCategoryActionWithInvalidData() throws Exception {
//GIVEN
String categoryId = "category_001";
Store store = storeBuilder.getTestStore();
categoryBuilder.createListWithStore(5,store);
Category category = categoryBuilder.createWithId(categoryId);
//WHEN
this.mockMvc.perform(
put("/admin/categories/{categoryId}", categoryId)
.param("name", category.getName())
.param("title", category.getTitle())
.param("status", " ")
.param("store", store.getId())
.with(csrf())
)
//THEN
.andExpect(status().isOk())
.andExpect(view().name(CategoriesController.EDIT_VIEW_NAME))
.andExpect(model().attributeHasErrors("category"))
.andExpect(model().attributeHasFieldErrors("category", "status"))
;
}
}
删除了一些位以留出空间，但请注意顶部的@Transactional注释
它运行和通过没有线：
model.addAttribute("categories", categoryService.activeCategories(store));
但是在添加它时，它会给出这个讨厌的异常，这是一个没有任何数据插入操作的 bean 验证异常（Spring mvc 已经处理的验证错误和 BindingResult 中的结果）

当我删除类级别上存在的@Transactional时，一切都运行顺利，所以我认为这是交易中的一个问题
该行：
model.addAttribute("categories", categoryService.activeCategories(store));
是查找器查询的包装器：
@Transactional(readOnly = true)
public List<Category> activeCategories(Store store) {
return categoryRepository.findAllByStoreAndStatus(store, Category.STATUS_ENABLED);
}
只是一个选择的 quert，它不应该导致 Bean 验证错误
发生的情况是，我传递了一组无效数据来测试它不会通过，Spring mvc 捕获 BindingResult 中的错误，但似乎在测试方法结束时，某种事务回滚（我不确定，只是猜测）并尝试插入数据
如果我删除@Transactional注释，测试就会通过，但这对我来说不切实际，因为我的整个测试套件（950+ 测试）依赖于空数据库，以及我使用 @Transactional 实现它的方式来回滚对数据的任何更改
我认为问题是只读查询的刷新模式。 如果您使用的是休眠，则可以通过方法上的org.springframework.data.jpa.repository.QueryHints-Annotation将刷新模式设置为COMMIT（https://docs.jboss.org/hibernate/orm/4.3/javadocs/org/hibernate/jpa/QueryHints.html#HINT_FLUSH_MODE）。
我只能猜测这一点...等待你对我问题的回答。但我认为您有一个@ModelAttribute注释的方法，可以查找类别对象（类似于 http://www.javabeat.net/modelattribute-spring-mvc/）
这就是为什么加载类别对象，然后由请求中的数据修改，删除状态值 => 类别对象，其中包含 entityManager 中包含的无效数据，提交查询时会刷新该数据。
这个问题也可以通过调用entityManager.clear（）或entityManager.detach（category）来缓解。
你应该知道，你所做的每一次修改都会，即使你的控制器没有显式调用持久/更新，如果实体是从非只读存储库方法获取的，否则将写入数据库，除非有事务回滚（通过引发异常或手动告诉事务回滚）http://docs.spring.io/spring-framework/docs/2.5.6/api/org/springframework/transaction/TransactionStatus.html#setRollbackOnly%28%29）
。编辑
这就是为什么测试在没有@Transactional回滚的情况下工作的原因，因为当调用@ModelAttribute注释的方法时没有事务=> entityManager立即关闭，因此在提交查询时不会刷新对类别的更改。
