spring security bean not found exception

spring security bean not found exception

I'm trying to set up spring security for an mvc project, and I'm having a
hard time. I'm using the spring security 3.1.4.Release. I have a
spring-security.xml file set up along with and mvc-dispatcher-servlet file
set up for configuration. Right now I'm getting a bean not found exception
for my User Details Bean.
In intellij I get a "cannot resolve bean" message for the
myUserDetailService. I also cannot resolve the package "controller". The
root error when I run the project is:
Caused by: org.springframework.beans.factory.BeanCreationException: Error
creating bean with name
'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0':
Cannot resolve reference to bean 'myUserDetailService' while setting bean
property 'userDetailsService'; nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean
named 'myUserDetailService' is defined

Here is my spring-security.xml file:

I'm basically trying to follow this tutorial:
http://kh-yiu.blogspot.com/2012/12/spring-mvc-security-custom.html and the
UserDetailServiceImpl is pretty identical to that, but I do have it in a
different folder in my main/java directory. It's important to note I use
annotations to declare the class:
@Service("myUserDetailService")
public class UserDetailsServiceImpl implements UserDetailsService{
Any ideas? I'm having a very hard time finding tutorials with the same
spring version that I'm using, so it's quite possible I've messed up xsd
refs. Thanks.
