How to fully disable swagger-ui in spring-boot?(/swagger-ui.html should return 404)

My answer is similar to the answer provided earlier with a slight difference. I usually create a separate spring profile named swagger. When I want to enable Swagger, l pass the following VM flag while starting my application, -Dspring.profiles.active=swagger. Here is an example of my Swagger configuration,

@Profile(value = {"swagger"})
@Configuration
@EnableSwagger2
public class SwaggerConfiguration {
    ...
}

Next time when you try to access swagger-ui.html without swagger profile, you will get an empty Swagger screen but not 404.

If you don't want to load the static Swagger UI page at all, you can write a simple controller as shown below,

@Profile("!swagger")
@RestController
@Slf4j
public class DisableSwaggerUiController {

    @RequestMapping(value = "swagger-ui.html", method = RequestMethod.GET)
    public void getSwagger(HttpServletResponse httpResponse) throws IOException {
        httpResponse.setStatus(HttpStatus.NOT_FOUND.value());
    }
}

Now if you try to access swagger-ui.html without swagger profile, you will get a 404.

You can externalize the @EnableSwagger2 to its own @Configruation and load it conditionally via a property or profile. e.g.

@Profile("!production")
@Configuration
@EnableSwagger2
public class SwaggerConfiguration{
    //Additional Swagger Beans

}

this would activate swagger for any profile that isn't production.

If you dont have Swagger annotations inside controllers... just exclude SwaggerConfig.class and swagger dependencies on build
