I have literally tried every solution present in the internet for this Error and none has worked for me. So, I'm asking again if anyone has any updated solution, then please help!.
As you can see in the dispatcher.xml file I have already tried using the ContextLoader, but it gave me a 404 File Not Found. I saw a similar post in Stack Overflow which said to mention the @Controller, but I had already done that and I was still getting the 404 Error.
I have also tried with the load-on-startup 1 /load-on-startup approach but that still didn't work.
