Java 将@EnableWebMvc与@EnableContextResourceLoader（SpringCloudAWS注释）组合时发生冲突的应用程序上下文

我正在尝试使用SpringCloudAWS与AmazonS3集成。该应用程序基于web，并在配置上使用@EnableWebMvc。当我添加@EnableContextResourceLoader注释以便可以访问S3存储桶中的文件时，我在引导时收到以下异常：

org.springframework.context.ApplicationContextException: Cannot reinitialize with different application context: current one is [WebApplicationContext for namespace 'apiv1-servlet': startup date [Thu May 28 10:17:58 EDT 2015]; parent: Root WebApplicationContext], passed-in one is [WebApplicationContext for namespace 'apiv1-servlet': startup date [Thu May 28 10:17:58 EDT 2015]; parent: Root WebApplicationContext]

下面是ApiV1Config类，该类具有@EnableWebMvc注释，并加载BullhornIntegrationConfig类，该类可以进一步查看：

@Configuration
@EnableWebMvc
@ComponentScan("com.aquent.api.controller.v1")
@Import({ PropertySourcesConfig.class,
        OrderContainerServiceConfig.class,
        JobPostingServiceConfig.class,
        ZipRecruiterUtilsConfig.class,
        AuthenticationTokenServiceConfig.class,
        BullhornIntegrationConfig.class,
        TruTimeFileServiceConfig.class })
@ImportResource({ "classpath:com/aquent/config/order-service-v2/order-service-v2-beans.xml",
        "classpath:com/aquent/config/activity-service-v1/activity-service-v1-beans.xml",
        "classpath:com/aquent/config/email-service-v2/email-service-v2-beans.xml",
        "classpath:com/aquent/config/email-tracking-service-v1/email-tracking-service-v1-beans.xml",
        "classpath:com/aquent/config/contact-service-v3/contact-service-v3-beans.xml",
        "classpath:com/aquent/config/talent-service-v2/talent-submittal-service-beans.xml",
        "classpath:com/aquent/config/security-service-v1/security-service-beans.xml" })
public class ApiV1Config extends WebMvcConfigurerAdapter {
    // Unrelated methods (e.g. overriding configureMessageConverters(), etc.)
}

下面是BullhornIntegrationConfig类，用于配置amazon云aws生态系统：

@Configuration
@EnableContextCredentials(accessKey = "${bullhorn.aws.access-key}", secretKey = "${bullhorn.aws.secret-key}")
@EnableContextRegion(region = "${bullhorn.aws.region}")
@EnableContextResourceLoader
@EnableSqs
public class BullhornIntegrationConfig {

    @Bean
    public QueueMessagingTemplate queueMessagingTemplate(AmazonSQS amazonSQS, ResourceIdResolver resourceIdResolver) {
        return new QueueMessagingTemplate(amazonSQS, resourceIdResolver);
    }
}

如果我注释掉@EnableWebMvc注释或@EnableContextResourceLoader注释，引导将正常完成，并且当@EnableWebMvc存在时，我可以访问web服务；当@EnableContextResourceLoader存在时，我可以访问Amazon S3服务。我一直无法找出冲突的根源

我已经寻找了一种方法，可以手动定义访问S3存储桶所需的资源加载器，但在实例化SimpleStrageResourceLoader时，我遇到了一个障碍，试图获取对适当AmazonS3实例的引用

我的问题是：我如何解决@SpringWebMvc和@EnableContextResourceLoader注释之间的冲突，或者手动配置资源加载器以加载S3文件
