Spring 事务导致 spring-mvc 集成测试失败

许博易
2023-03-14

我正在使用Spring引导 1.3 开发一个 spring 应用程序

我有一个类似这样的MVC请求处理程序:

@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));

但是当添加它时，它给出了这个讨厌的异常，这是一个bean验证异常，没有任何数据插入操作（Spring mvc已经处理的验证错误和BindingResault中的结果）

当我在类级别上删除@Transactionic存在时，一切都运行顺利，所以我认为这是事务中的一个问题

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);
    }

它只是一个select quert，绝不会导致bean验证错误

发生的情况是，我传递了一组无效数据以测试它不会通过，spring mvc在BindingResult中捕获错误，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

如果我删除了@Transactional注释，测试就通过了，但是这对我来说并不实际，因为我的整个测试套件(950个测试)依赖于空数据库，而且我实现它的方式是使用@Transactional回滚对数据的任何更改

我认为问题在于只读查询的刷新模式。如果使用hibernate，可以通过org . spring framework . data . JPA . repository . query hints-Annotation将刷新模式设置为提交(https://docs . JBoss . org/hibernate/ORM/4.3/javadocs/org/hibernate/JPA/query hints . html # HINT _ FLUSH _ MODE)。

我只能在这一点上猜测…等待你对我的问题的回答。但是我认为你有一个@Model属性注释的方法来查找类别对象（类似于http://www.javabeat.net/modelattribute-spring-mvc/）

这就是为什么加载 Category-对象，然后由请求中的数据修改，删除状态值 =

这个问题也可以通过调用entityManager.clear（）或entityManager.detach（category）来缓解。

我猜您已经准备好了OpenEntityManagerInViewFilter。您应该知道，即使在控制器没有显式调用persist/update的情况下，如果从非readOnly-repository获取实体，您所做的每个修改都将被写入数据库，除非存在事务回滚(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/spring framework/transaction/transaction status . html # setRollbackOnly())

…编辑

啊。这就是为什么测试在没有@Transactional回滚的情况下工作的原因，因为调用@ModelAttribute注释方法时没有事务=
