Using the changed default behavior for path mapping

The default behavior of map extensions such as .json and .xml to existing controller request mappings has changed in Spring Boot 2.0. Consider the following URL mapping:

@GetMapping("/users")

If it is expected to cater to the /users.json URL in a Spring Boot 1.x application, then it won't be supported in Spring Boot 2.0. This means new mappings need to be added as necessary.
