springfox: cannot integrate swagger springmvc using SwaggerSpringMvcPlugin

The problem is: org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘mySwaggerConfig’: Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.util.List com.mangofactory.swagger.configuration.SpringSwaggerConfig.handlerMappings; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] found for dependency [collection of org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

MySwaggerConfig is the same in sample ‘SwaggerSpringMvcPlugin XML Configuration’. Spring config is:

There are no issues to use by ‘quick guide(Spring xml Configuration)’ of docs, but when I try to use custom config I got the error. Could you please help me to resolve the problem?

There are two contexts, the default spring context and the spring MVC context. If you’re using the @Configuration annotation, that gets picked up by the default spring context scanning which has no visibility of the RequestMappingHandlerMapping. That’s why it’s important that the SwaggerConfig is a bean defined in the MVC context.

@dilipkrish yeah thanks a lot for the reply! Seems but I’m not sure the same. You know if I remove @Configuration annotation of MySwaggerConfig (just keep @EnableSwagger) it works fine without any errors.

I was having the same problem and am using the XML configuration. I removed the @Configuration attribute from my SwaggerConfig and it worked fine.

@magnusmagister this seems like a similar issue
