Integrate Swagger with Spring Boot 2

Hi guys, 

I am trying to use swagger along with my spring boot 2 application but i can not succeed. Is there anything that I am missing ? I want to mention that i successfully integrated Swagger with Spring boot 1 so I am not a newbee in this domain. Please help me out. Thank you.
