@SpringbootApplication 어노테이션에 아래와 같은 코드를 추가해주면 된다.

@SpringBootApplication(
        exclude = {
                org.springframework.cloud.aws.autoconfigure.context.ContextInstanceDataAutoConfiguration.class,
                org.springframework.cloud.aws.autoconfigure.context.ContextStackAutoConfiguration.class,
                org.springframework.cloud.aws.autoconfigure.context.ContextRegionProviderAutoConfiguration.class
        }
)
