予想される一致する単一のBeanが見つかりましたが、3が見つかりました：junitTestのobjectMapper、halObjectMapper、_halObjectMapper

Question

私のテストに問題があります。私はjava springを使用していて、junit testを実行して自分のサーバーが生存しているかどうかを確認しようとしています。

このテスト私がしようとしている：

@WebAppConfiguration 
abstract class AbstractTestController : DatabaseInitializedTest() { 

@Autowired 
lateinit var webAppContext: WebApplicationContext 

lateinit var mockMvc: MockMvc 


@Autowired 
lateinit var authHelper: OAuthHelper 



@Autowired 
private lateinit var userService: UserService 

fun adminToken(username: String) = authHelper.addBearerToken(userService.getUserByUsername(username), *AuthoritiesService.adminAuthorities.toTypedArray()) 

fun clientItToken(username: String) = authHelper.addBearerToken(userService.getUserByUsername(username), *AuthoritiesService.clientItAuthorities.toTypedArray()) 
fun clientManagerToken(username: String) = authHelper.addBearerToken(userService.getUserByUsername(username), *AuthoritiesService.clientManagerAuthorities.toTypedArray()) 

fun endUserToken(username: String) = authHelper.addBearerToken(userService.getUserByUsername(username), *AuthoritiesService.endUserAuthorities.toTypedArray()) 

@Autowired 
lateinit var mapper: ObjectMapper 


fun <T> ResultActions.and200ReturnClass(clazz: TypeReference<T>): ResultActions { 
if (this.andReturn().response.status == HttpServletResponse.SC_OK 
    && this.andReturn().response.contentAsString.isNotEmpty()) { 
    mapper.readValue<T>(this.andReturn().response.contentAsString, clazz)!! 
    } 
return this 
} 

@Before 
fun initialize() { 
mockMvc = MockMvcBuilders 
    .webAppContextSetup(webAppContext) 
    .apply<DefaultMockMvcBuilder>(SecurityMockMvcConfigurers.springSecurity()) 
    .alwaysDo<DefaultMockMvcBuilder>(MockMvcResultHandlers.print()) 
    .build() 
    } 
} 

マイ設定：

@RunWith(SpringJUnit4ClassRunner::class) 
    @ContextConfiguration(classes = arrayOf(ServiceContext::class,DatabaseContext::class)) 
@Transactional 
open class newtest : AbstractTestController(){ 

@Test 
fun echoTest() { 
    mockMvc.perform(get("/echo").contentType(MediaType.APPLICATION_JSON)).andExpect(status().isOk) 
    } 
} 

これは私newtestクラスはを拡張さAbstractTestControllerクラスです

@Configuration @Import(value = *arrayOf( OAuth2ServerConfiguration::class, OAuth2ServerConfiguration.AuthorizationServerConfiguration::class, OAuth2ServerConfiguration.ResourceServerConfiguration::class, SecurityConfig::class, OAuthHelper::class, WebConfig::class, DatabaseInitializator::class, LowerCaser::class)) @ComponentScan("com.hyg","com.hyg.service", "com.hyg.web", "com.hyg.utils") @EnableAutoConfiguration @EnableAspectJAutoProxy(proxyTargetClass = true) open class ServiceContext @Configuration @EnableJpaRepositories("com.hyg") @EnableTransactionManagement @EnableAutoConfiguration @PropertySource("classpath:application.properties") open class DatabaseContext { val DATA_PACKAGE = "com.hyg.data" val INTERCEPTOR_KEY = "hibernate.ejb.interceptor" @Value("\${spring.datasource.username:${Const.NONE}}") lateinit var username: String @Value("\${spring.datasource.url}") lateinit var url: String @Value("\${spring.datasource.driverClassName}") lateinit var driverClass: String @Value("\${spring.datasource.password}") lateinit var password: String @Bean @Primary open fun objectMapper(): ObjectMapper { val mapper = ObjectMapper() mapper.registerModule(KotlinModule()) mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, true) mapper.configure(MapperFeature.USE_STD_BEAN_NAMING, true) mapper.configure(DeserializationFeature.ACCEPT_FLOAT_AS_INT, false) mapper.registerModule(JavaTimeModule()) mapper.registerModule(localDateTimeSerializer()) return mapper } @Bean open fun localDateTimeSerializer(): SimpleModule { val localDateTimeSerializer = SimpleModule() val serializer = LocalDateTimeSerializer( DateTimeFormatter.ofPattern(Const.DATE_TIME_PATTERN)) val deserializer = LocalDateTimeDeserializer( DateTimeFormatter.ofPattern(Const.DATE_TIME_PATTERN)) localDateTimeSerializer.addSerializer(LocalDateTime::class.java, serializer) localDateTimeSerializer.addDeserializer(LocalDateTime::class.java, deserializer) return localDateTimeSerializer } @Bean open fun dataSource(): DataSource { val ds = DataSourceBuilder.create().driverClassName(driverClass).username(username).password(password).url(url).build() val proxy = ProxyDataSource() proxy.setDataSource(ds) proxy.setListener(DataSourceQueryCountListener()) return proxy } @Bean open fun entityManagerFactory( factory: EntityManagerFactoryBuilder, dataSource: DataSource, properties: JpaProperties): LocalContainerEntityManagerFactoryBean { val jpaProperties = HashMap<String, Any>() jpaProperties.putAll(properties.getHibernateProperties(dataSource)) jpaProperties.put(INTERCEPTOR_KEY, hibernateInterceptor()) return factory.dataSource(dataSource).packages(DATA_PACKAGE) .properties(jpaProperties as MutableMap<String, *>) .build() } @Bean open fun hibernateInterceptor(): HibernateStatisticsInterceptor { return HibernateStatisticsInterceptor() } @Bean open fun requestStatisticsInterceptor(): RequestStatisticsInterceptor { return RequestStatisticsInterceptor() } } 

これは私が取得していますフルエラーです：

が、それは私の問題を解決するのに役立ちます願っています。 私はObjectMapperを作るそのビーンに@Primaryを入れて、これまでにしようとしたか、それらの注釈@Order @ConditionalOnMissingBeanを追加するが、それは動作しませんでした... はあなたがタイプObjectMapperを持ついくつかの豆を持っているあなたに

Answer 1

ありがとうございましたSpringコンテキストでは（AbstractTestControllerに）mapperのための注釈@Qualifier("objectMapper")を追加したり、objectMapperに名前を変更してみてください：

@WebAppConfiguration 
abstract class AbstractTestController : DatabaseInitializedTest() { 
... 
@Qualifier("objectMapper") 
@Autowired 
lateinit var mapper: ObjectMapper 
... 
} 

または

@WebAppConfiguration 
abstract class AbstractTestController : DatabaseInitializedTest() { 
... 
@Autowired 
lateinit var objectMapper: ObjectMapper 
... 
}
