And a screenshot of my project structure.

How could I go about this?

( i am using tomacat 8.5.16 and spring-mvc 5.0.8 )

I think this question had already been answered here. I think you let Intellij generate your context file and added the cashe namespace. IntelliJ automatically imports the ****/cache namespace instead of the ****/tx namespace

I dont know, if it was automatically assigned then why am i getting error? – Wasi Khan Oct 18 '18 at 13:06
Just spotted your error, in your spring configuration file: xmlns:mvc="http://www.springframework.org/schema/cache" Change it to: xmlns:mvc="http://www.springframework.org/schema/mvc" Spring is searching for a cache manager when you're enabling annotations – amineT Oct 18 '18 at 13:48
i changed it but still getting error, its showing me inside the project structure that "Unmapped Spring configuration files" i mapped them inside a new application context , gave the parent context and the errors were solved but even them i am getting the same error – Wasi Khan Oct 18 '18 at 13:58
GOT IT! i reperformed everything and realized in server configuration i had set the build (project war file) first and then the default build which was actually vice versa and thank you @amineT for making the note on the point on annotations – Wasi Khan Oct 18 '18 at 15:57
Glad I could help – amineT Oct 19 '18 at 14:23
