Greetings! For some reason IntelliJ shows an error here:

Tried to load completed project but still have the same problem. When I run app everything works fine, but that's still annoying. I used @SuppressWarnings("SpringJavaAutowiringInspection") to supress that warning from IDE, but I wonder why Chris doesn't have that error.

Trying here and there, I also tried adding @ComponentScan('com.teamtreehouse') on top of the SecurityConfig class. It seems to work as well.
It is just we have to tell Intellijidea where to look for beans. Judging by StackOverflow posts, people know where and how to create proper application configuration files with settings where is which. I'm unfortunately not so good at this yet.

Java Web Development Techdegree Graduate 22,175 PointsThe reason, Chris didn't get this error, because he is using Community Edition of IntellijIdea, whereas you probably are using Ultimate edition. Because only in Ultimate edition IntellijIdea is helping you with Spring Configuration. Chris used IntellijIdea Community Edition 2016.1.3 I think. I tried the same version - no error. Now I have ultimate version as well, and in it there is such error. If however you are using Community Edition, that error is strange...

7,156 PointsI noticed that my UserServiceImpl wasn't annotated with @Service. Doing only that fixed my error. I did not have to annotate with @SuppressWarnings... or Componentscan either. Which makes sense to me because just annotating with @Service makes it being scanned on bootrun.

Java Web Development Techdegree Graduate 22,175 PointsI edited answer: try writing (I mistyped package name):
@ComponentScan("com.teamtreehouse")
Also keep in mind that @SuppressWarnings will also help:
@SuppressWarnings("SpringJavaAutowiringInspection")

@SuppressWarnings("SpringJavaAutowiringInspection")
@Autowired
private UserService userService;
