Base path about swagger project - spring

Question

I started to learn swagger in May 8th and completed my first project with swagger in today.
The page occurred but has a fatal problem that the base path of project didn't show ![enter image description here][1]and api list occurred error like(I don't have enough reputation so I describe the error):
expect Request URL is ：http://localhost:8080/TestFF/addUser?postData=11
now : http://localhost:8080/addUser?postData=11
I try about two or three ways to config the project but still without base path.
My configuration just like:
web.xml:

I'm not so sure weather if this problem relate to controller or not so I will paste the code for you if it's necessary.
