本文介绍了@WebMvcTest 因 java.lang.IllegalStateException 失败:无法加载 ApplicationContext的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在使用 @WebMvcTest 注释我的测试时遇到问题.我还配置了spring-cloud-config-server和spring-cloud-starter，所有带有这个注解的Test类好像都失败了.我有以下控制器测试:
I'm having trouble getting my tests annotated with @WebMvcTest to work. I have also configured spring-cloud-config-server and spring-cloud-starter, and all Test classes with this annotation seem to fail. I have the following controller test:
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:
It is worth mentioning that as a result of my spring-cloud configurations I also had to update the META-INF/spring.factories file and update my main ServerApplication class with the following annotations:
@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，我得出的结论可能是 @WebMvcTest 配置为 @Configuration 或 @ 的类存在问题EnableConfig 服务器，但我尝试过的一切都没有帮助我解决这个问题.
Conclusion:After a lot of searching I came to the conclusion that it probably has to be something with the fact that @WebMvcTest has problems with classes configured as @Configuration or @EnableConfig server but everything I have tried hasn't helped me solve this issue.
推荐答案
我找到了我遇到这个问题的原因.来自 spring 文档 @SpringBootApplication:
I found the reason I was having this problem.From spring docs @SpringBootApplication:
表示声明一个或多个@Bean方法并触发自动配置和组件扫描的配置类.这是一个方便的注解，相当于声明了@Configuration、@EnableAutoConfiguration 和@ComponentScan.
然而，这是@SpringBootApplication注解的完整声明:
However, this is the full declaration of the @SpringBootApplication annotation:
@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.
When I added the @ComponentScan annotation directly in my application class I did not specify the default excludedFilters and that is why the behavior was different. After adding the excludeFilter I was able to solve my issue.
