Access Spring beans from a servlet in JBoss

by

There is a much more sophisticated way to do that. There is SpringBeanAutowiringSupportinside org.springframework.web.context.support that allows you building something like this:

public class MyServlet extends HttpServlet {

  @Autowired
  private MyService myService;

  public void init(ServletConfig config) {
    super.init(config);
    SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this,
      config.getServletContext());
  }
}

This will cause Spring to lookup the ApplicationContext tied to that ServletContext (e.g. created via ContextLoaderListener) and inject the Spring beans available in that ApplicationContext.
