title: Spring Security: No bean named 'springSecurityFilterChain' is defined
body: <p>I just equipped a simple Spring test project with basic authentication functionality. When the server is loaded I get the well-known error 
  <strong>org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'springSecurityFilterChain' is defined</strong>. </p>
