Swagger-UI giving 405 (Method not allowed) when called

I’ve added the swagger and swagger-ui dependencies as well as the “@enableSwagger2” annotation. When I go to localhost:8080/swagger-ui.html, I get the error message pasted below. This error is fixed by changing another endpoint which has the path of “/**”. The part which makes me think this is a bug in springfox is that all the other endpoints interact nicely with that method (which is used for CORS) whereas it doesn’t seem to get past the annotation for requestMapping when using swagger-ui. Please let me know if any other information is required.

Using @RestController("/some-path") causes many problems, not only with Swagger UI. In RestController’s javadoc we can see the following:

/**
   * The value may indicate a suggestion for a logical component name,
   * to be turned into a Spring bean in case of an autodetected component.
   * @return the suggested component name, if any (or empty String otherwise)
   * @since 4.0.1
   */

So this property is not about paths at all and should not be used for that. The right way to set the base path for a rest controller is:

@RestController
@RequestMapping("/some-path")

Why has this issue been closed?

Seems to be the same problem for me as for jaychang9:

This code leads to a HTTP 405 error:

@RestController
public class VerteilOrganisationenController {

	@RequestMapping(value = "/verteilorganisationen", method = RequestMethod.GET)
	public Iterable<VerteilOrganisationenEntry> getVerteilOrganisationen() {

		...
	}
...
}

This works fine:

@RestController
@RequestMapping("/")
public class VerteilOrganisationenController {

	@RequestMapping(value = "/verteilorganisationen", method = RequestMethod.GET)
	public Iterable<VerteilOrganisationenEntry> getVerteilOrganisationen() {

		...
	}

So adding @RequestMapping(“/”) is a quick workaround - but this looks like an error. Or do a miss something?
