actuator status: 404

해결했습니다.

SwaggerConfig.java 안에 아래 bean 을 설정해 주면 됩니다.

기타 궁금한 사항은 

https://github.com/springfox/springfox/issues/3462 

여기 들어가면 있습니다.

	@Bean
	public WebMvcEndpointHandlerMapping webEndpointServletHandlerMapping(WebEndpointsSupplier webEndpointsSupplier, ServletEndpointsSupplier servletEndpointsSupplier, ControllerEndpointsSupplier controllerEndpointsSupplier, EndpointMediaTypes endpointMediaTypes, CorsEndpointProperties corsProperties, WebEndpointProperties webEndpointProperties, Environment environment) {
	        List<ExposableEndpoint<?>> allEndpoints = new ArrayList();
	        Collection<ExposableWebEndpoint> webEndpoints = webEndpointsSupplier.getEndpoints();
	        allEndpoints.addAll(webEndpoints);
	        allEndpoints.addAll(servletEndpointsSupplier.getEndpoints());
	        allEndpoints.addAll(controllerEndpointsSupplier.getEndpoints());
	        String basePath = webEndpointProperties.getBasePath();
	        EndpointMapping endpointMapping = new EndpointMapping(basePath);
	        boolean shouldRegisterLinksMapping = this.shouldRegisterLinksMapping(webEndpointProperties, environment, basePath);
	        return new WebMvcEndpointHandlerMapping(endpointMapping, webEndpoints, endpointMediaTypes, corsProperties.toCorsConfiguration(), new EndpointLinksResolver(allEndpoints, basePath), shouldRegisterLinksMapping, null);
	    }


	private boolean shouldRegisterLinksMapping(WebEndpointProperties webEndpointProperties, Environment environment, String basePath) {
	        return webEndpointProperties.getDiscovery().isEnabled() && (StringUtils.hasText(basePath) || ManagementPortType.get(environment).equals(ManagementPortType.DIFFERENT));
	    }

안녕하세요, 이도원입니다 .

actuator 관련 dependecy가 정상적으로 설정되었다면, Spring Boot나 Actuator의 버전은 상관없을 것 같습니다. 다음은 Spring Boot, Actuator를 2.6.2 버전으로 설정하였을 때의 결과화면입니다. 

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
<!--        <version>2.1.8.RELEASE</version>-->
        <version>2.6.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

추가로, application.yml 파일에 autuator 사용을 위한 다음과 같은 설정이 추가되었는지 확인해 보시기 바랍니다.

management:
  endpoints:
    web:
      exposure:
        include: "*"

감사합니다.
