Spring Problems: Error creating beans and injecting auto-aware dependencies

Question

Spring Problems: Error creating beans and injecting auto-aware dependencies

So, I'm trying to learn spring, and I read a lot of lessons and tried to copy the code from the project that I have on the flash drive.

I already installed tomcat and it works, but I still have problems. The fact is that I can normally access the controller’s action from my browser without problems, but when I started adding annotations and ContextLoaderListener, it always gave me the status 404. I don’t know what I did, but changing some things, my browser, at least, is trying to contact the controller again. But it produces a huge error log, which I will discuss at the end of this post.

These are my dependencies:

junit 4.12
spring -webmvc 4.1.6.RELEASE
spring -context 4.1.6.RELEASE
spring -web 4.1.6.RELEASE
spring - beans 4.1.6.RELEASE
spring -data-jpa 1.8.0.RELEASE
spring -jdbc 4.1.6.RELEASE

My build plugins:
