为什么春季测试失败了，所以无法使用@MockBean [英] Why spring test is fail, does not work @MockBean

问题描述

我尝试为一个简单的spring-boot控制器创建我的第一个测试，但得到Handler: Type = null.在浏览器中，代码有效，但测试失败.我的应用程序使用spring-security.请帮助我解决问题并了解我的错误.谢谢.

I try to create my first the test for a simple spring-boot controller but I get Handler: Type = null. In browser code is work but a test fails. My App use spring-security. Please help me fix it an issue and understand my mistake. Thank You.

这是控制者:

private final ItemService service;

@GetMapping("/get_all_items")
public String getAllItems(Model model) {
    model.addAttribute("items", service.getAll());
    return "all_items";
}

这是一个测试.

@RunWith(SpringRunner.class)
@WebMvcTest(ItemController.class)
public class ItemControllerTest {

    @Autowired
    private MockMvc mvc;

    @MockBean
    private ItemService itemService;

    @Test
    @WithMockUser(username = "user", roles = "user")//mock security.
    public void whenGetAllItemsThenControllerReturnAllItems() throws Exception {
        given(
            itemService.getAll()
        ).willReturn(
                new ArrayList<Item>()
        );

        mvc.perform(
            get("/get_all_items").accept(MediaType.TEXT_HTML)
        ).andExpect(
                status().isOk()
        );
    }
}

这是结果日志:

推荐答案

这本质上是一个重复的问题，已在此处回答: https ://stackoverflow.com/a/38676144/388980

This is essentially a duplicate question that has been answered here: https://stackoverflow.com/a/38676144/388980

解决方案除了为@WebMvcTest(ItemController.class)这样声明@WebMvcTest(ItemController.class)之外，还为Spring Security配置 import 类@Configuration(假定您对Spring Security的自定义配置位于名为的类中SecurityConfig).

The solution is to import the @Configuration class for your Spring Security configuration in addition to declaring @WebMvcTest(ItemController.class) like this @Import(SecurityConfig.class) (assuming your custom configuration for Spring Security is in a class named SecurityConfig).

您可能还会发现Spring Boot的问题跟踪器中的讨论也很有帮助: https://github.com/spring-projects/spring-boot/issues/6514

You might also find the discussion in Spring Boot's issue tracker helpful as well: https://github.com/spring-projects/spring-boot/issues/6514

另一种选择是禁用 Spring Security，如下所述:

The other option is to disable Spring Security as explained here: Disable security for unit tests with spring boot
