Do you have a bean declared in your context file that has an id of  articleService   I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire

The error shows that com bd service ArticleService is not a registered bean  Add the packages in which you have beans that will be autowired in your application context     lt context component-scan base-package  com bd service   gt   lt context component-scan base-package  com bd controleur   gt    Alternatively  if you want to include all subpackages in com bd     lt context component-scan base-package  com bd  gt        lt context include-filter type  aspectj  expression  com bd      gt   lt  context component-scan gt    As a side note  if you re using Spring 3 1 or later  you can take advantage of the  ComponentScan annotation  so that you don t have to use any xml configuration regarding component-scan  Use it in conjunction with  Configuration    Controller  RequestMapping   Article GererArticle    Configuration  ComponentScan  com bd service      No need to include component-scan in xml public class ArticleControleur         Autowired     ArticleService articleService              You might find this Spring in depth section on Autowiring useful
