/swagger-resources/configuration/ui 404 error - spring-mvc

Question

I'm running in springfox v2.7.0 in my java spring based application. We have 3 dispatch serverlets configured in web.xml:
1)common springmvc servlet [Active]
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/config/common/springmvc-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>`
2 ) springmvc-v1 servlet [inactive]: which is disabled by commenting out it in web.xml and not in use.
<servlet>
<servlet-name>springmvc-v1</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextClass</param-name>
<param-value>
org.springframework.web.context.support.AnnotationConfigWebApplicationContext
</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
com.test.mywebservices.v1.config.WebConfig
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
3)springmvc-v2 servlet [Active]: for this I am implimenting swagger.
<servlet>
<servlet-name>springmvc-v2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextClass</param-name>
<param-value>
org.springframework.web.context.support.AnnotationConfigWebApplicationContext
</param-value>
</init-param>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
com.test.mywebservices.v2.config.WebConfig
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc-v2</servlet-name>
<url-pattern>/v2/*</url-pattern>
</servlet-mapping>
And it works fine, and i can get to the swagger-resources from here:
https://localhost:9002/mywebservices/v2/swagger-resources
And i can view the api from here:
https://localhost:9002/mywebservices/v2/v2/api-docs
And Swagger-UI is accessible from here:
https://localhost:9002/mywebservices/swagger-ui.html
The problem is when i load the https://localhost:9002/mywebservices/swagger-ui.html page it is trying to access the swagger-resources from here:
https://localhost:9002/mywebservices/swagger-resources
And they are not available. But it is available at https://localhost:9002/mywebservices/v2/swagger-resources
How can i fix this so that the swagger-ui.html :
I think Swagger-ui.html should be available at: https://localhost:9002/mywebservices/v2/swagger-ui.html so that springfox.js will get the right baseUrl.
https://localhost:9002/mywebservices/swagger-ui.html >>> pages loads but gives popup to enter the Base URL
https://localhost:9002/mywebservices/swagger-resources/configuration/ui >>> gives 404 hence popup appears
https://localhost:9002/mywebservices/webjars/springfox-swagger-ui/springfox.js >>> Able to access.This is working fine.
Please suggest the solution.
Thanks in advance.

I was facing the same problem.
The solution was to map on the MVC config of your app, manually the Controller managing the mapping of swagger-resources that exists on swagger-common.jar. The package value is "springfox.documentation.swagger.web". The configuration, depending on your app, should look similar that the one shown below:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages = { ApplicationPackages.REST_CONTROLLER_BASE_PACKAGE,
"springfox.documentation.swagger.web" })
public class MvcConfig extends WebMvcConfigurerAdapter {
}
