@WebMvcTest 因 java.lang.IllegalStateException 失败：无法加载 ApplicationContext答案

【问题描述】：

我无法让使用 @WebMvcTest 注释的测试正常工作。我还配置了spring-cloud-config-server和spring-cloud-starter，所有带有这个注解的Test类似乎都失败了。我有以下控制器测试：

代码：

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = UserController.class)
@ActiveProfiles({"dev", "native"})
public class UserControllerTest {

    @MockBean
    private UserService userService;
    @Autowired
    private MockMvc mockMvc;
    @Autowired
    private ObjectMapper objectMapper;

    @Test
    public void changePassword() throws Exception {
        given(userService.changePassword(any(), any(), any())).willReturn(true);
        MvcResult result = mockMvc.perform(post(/user/changePassword)
                .param("old", "Pa$$W0rd")
                .param("new, "NewPa$$W0rd"))
                .andExpect(status().isOk()).andReturn();
        assertThat(result).isNotNull();
    assertThat(result.getResponse().getContentAsString()).isEqualTo("true");
    }
}

相关控制者：

@RestController
@RequestMapping(/user)
@Log4j2
public class UserController {

    private UserService userService;

    public UserController(UserService userService) {
        this.userService = userService;
    }

    @Timed
    @PostMapping(value = /changePassword)
    public ResponseEntity changePassword(@RequestParam("old") String oldPassword,
                                         @RequestParam("new") String newPassword) throws Exception {
        String username = SecurityUtil.getCurrentLogin();
        Boolean result = userService.changePassword(username, oldPassword, newPassword);
        return new ResponseEntity<>(result, HttpStatus.OK);
    }
}

值得一提的是，由于我的 spring-cloud 配置，我还必须更新 META-INF/spring.factories 文件并使用以下注释更新我的主 ServerApplication 类：

@Configuration
@EnableAutoConfiguration
@SpringBootConfiguration
@ComponentScan(excludeFilters = {@ComponentScan.Filter(type= FilterType.ASSIGNABLE_TYPE, value=AppPropertiesConfiguration.class)})
@ServletComponentScan
@EnableConfigServer
@EnableRetry
@Log4j2
public class ServerApplication {
...
...
}

运行测试后出现以下错误：

结论： 经过大量搜索后，我得出的结论是，@WebMvcTest 配置为@Configuration 或@EnableConfig 服务器的类可能存在问题，但我尝试过的一切都没有帮助我解决这个问题问题。

【问题讨论】：

尝试模拟 @MockBean private UserController userController; 而不是 @MockBean private UserService userService;
@Patrick 感谢您的回复，但这如何解决我的问题？ UserController 是我要测试的类。
但是，如果我在模拟我想测试的课程，我不是在测试我的课程的功能。重点是测试我的 Web 层的功能，因此我需要模拟我的服务，请参见此处：spring.io/blog/2016/08/30/…

标签： java spring spring-mvc spring-boot junit

【解决方案1】：

我只能通过使用@AutoConfigureMockMvc 结合@SpringBootTest 而不是@WebMvcTest 来解决它

   @RunWith(SpringRunner.class)
   @ComponentScan(basePackages = {"com.mypackage"})
   @SpringBootTest
   @AutoConfigureMockMvc
   public class MyClass{}

不知何故，我尝试过的与 @WebMvcTest 的所有其他组合都导致了同样的错误

【讨论】：

刚试过这个，但没有@WebMvcTest 注释我的SpringSecurity 有问题，因为我正在使用mockMvc.perform(get(path).with(user(TestConstants.USER_WRAPPER))).andReturn( ).getModelAndView().getModel()。现在需要认证的页面没有通过测试。

【解决方案2】：

我找到了我遇到这个问题的原因。来自 spring 文档@SpringBootApplication：

表示一个配置类，它声明了一个或多个@Bean 方法并且还触发了自动配置和组件扫描。这是一个方便的注解，相当于声明了@Configuration、@EnableAutoConfiguration 和@ComponentScan。

不过，这是@SpringBootApplication 注解的完整声明：

@Target(value=TYPE)
@Retention(value=RUNTIME)
@Documented
@Inherited
@SpringBootConfiguration
@EnableAutoConfiguration
@ComponentScan(excludeFilters={@ComponentScan.Filter(type=CUSTOM,classes=TypeExcludeFilter.class),})
public @interface SpringBootApplication

当我直接在我的应用程序类中添加 @ComponentScan 注释时，我没有指定默认的 excludeFilters，这就是行为不同的原因。添加 excludeFilter 后，我能够解决我的问题。
