title: How to call Component or Service from Controller in Spring MVC
body: <p>I want to save region ( property of authenticated User) in a class. Region list is fetched from Database and stored as a property for each User in Spring Controller Class suppose "A".</p>
  
  <p>Now this region property I want to fetch in spring interceptor "B" and want to validate the region for the user which I am getting as a parameter in each http request to that of stored in region property.</p>
  
  <p>I was suggested to use Service or Component to store region list so that Interceptor B and Controller Class A can both use that Service or Component.</p>
  
  <p>Can any one tell me how to use Service or Component in this case.</p>
