Subject Re: [Discuss] Do we need to add some reminder logs on SwaggerGeneratorContext selection?

Hi Haishi

It's important to let the user know about if there is some fallback
mechanism is used. In this way we could save user lot of time for the
trouble shooting. We also need to inform the user from log if there
are some important configuration information is loaded.

BTW, Please fill a JIRA to track this issue.

of the value specified in @RequestMapping.

logic to check whether there is @Path or @RequestMapping and remind developer to be aware
of the dependency jar files.
