Spring Boot 2.1.3.RELEASE and I wanted swagger-ui.html as home/welcome page and handel ROOT context (/)

Question

I have spring boot 2 and swagger API page working at http://localhost:8448/portalapi/swagger-ui.html. But I wanted to map http://localhost:8448/ and http://localhost:8448/portalapi/ to forward the request to http://localhost:8448/portalapi/swagger-ui.html. But it is not working. It gives HTTP Status 404 – Not Found (tomcat default response). Any help or pointer is greatly appreciated.

appliacation.properties

##
# tomcat server port
server.port=8448
#server.address=0.0.0.0

server.servlet.contextPath=/portalapi/

This is a webconfig class to context to forward:

   @Configurable
    @Component
    public class WebConfig implements WebMvcConfigurer {

        @Override
        public void addViewControllers(ViewControllerRegistry registry) {
            // forward requests to /admin and /user to their index.html
            registry.addViewController("/").setViewName(
                    "forward:/portalapi/swagger-ui.html");
            registry.addViewController("/portalapi/").setViewName(
                    "forward:/portalapi/swagger-ui.html");
        }

    }

The dispatcher servlet is mapped to `/portalapi` hence `/` will not pass through the dispatcherservlet. — M. Deinum, May 08 '19 at 08:20
@M.Deinum, how do I map /portalapi and / to dispathServlet? can you please help ? — Bmis13, May 09 '19 at 20:10
With `/` everything, including `/portalapi` are already mapped. — M. Deinum, May 13 '19 at 05:32

Change the below piece from :

@Configurable
@Component
public class WebConfig implements WebMvcConfigurer {

to:

@Configuration
public class WebConfig implements WebMvcConfigurer {

It did not work. As "/" is not mapped to dispatcherServlet. – Bmis13 May 09 '19 at 21:35
In your application.properties, `server.servlet.contextPath=/portalapi/` means you will not be having any mapping to `/`, instead you should be using `/portalapi` which is your context root. – snmaddula May 10 '19 at 05:43

Try redirect controller

@Controller
public class RedirectController {

    @RequestMapping(value = {"/","/portalapi/"})
    public String redirectToSwagger() {
        return "redirect:/portalapi/swagger-ui.html";
    }

}

Property file should not have server.servlet.contextPath=/portalapi/ or remove "/" from @RequestMapping(value = {"/","/portalapi/"}) – Tan mally Oct 07 '19 at 19:31
