[解決済み] ApplicationContext（アノテーション付き）の読み込みに失敗しました。

質問

これは私のテスト用のクラスです。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
public class UserServiceImplIT {

    @Autowired
    private SampleService sampleService; 

    @BeforeClass
    public static void setUp() {
        System.out.println("-----> SETUP <-----");
    }

    @Test
    public void testSampleService() {
        assertTrue(true);
    }
}      

例外（多くの例外、主な: Failed to load ApplicationContext ,
Error creating bean with name 'defaultServletHandlerMapping' .
Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'defaultServletHandlerMapping' threw exception; ,
A ServletContext is required to configure default servlet handling )

AppConfig - 基本的な設定ファイルです。

@Configuration
@ComponentScan("ru.moneymanager.web")
@EnableWebMvc

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled=true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    AuthenticationService authenticationService;

        CharacterEncodingFilter filter = new CharacterEncodingFilter();
        filter.setEncoding("UTF-8");
        filter.setForceEncoding(true);
        // отключена защита csrf на время тестов
        http.csrf().disable().addFilterBefore(filter,CsrfFilter.class);

    }
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(authenticationService);
    }   
}

どうしたんですか？なぜエラーになるのでしょうか？

解決方法は？

このテストでは、ServletContext が必要です。 @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...または、その他のオプションについては、こちらをご覧ください。 https://docs.spring.io/spring-framework/docs/current/reference/html/testing.html

アップデイト Spring Boot 1.4.x以降では @WebIntegrationTest は好まれなくなりました。 @SpringBootTest または @WebMvcTest
