public class springmvcinitializer extends abstractannotationconfigdispatcherservletinitializer {      @override     protected class<?>[] getrootconfigclasses() {         return new class<?>[] {appconfig.class, springmvcconfiguration.class};     }      @override     protected class<?>[] getservletconfigclasses() {         return null;     }      @override     protected string[] getservletmappings() {         return new string[] { "/" };     } } 

my autowired of accountdao returning null why? in web application works good.

i try lot of things like:

• create new sessionfactory doesn't work.
• used: classes ={appconfig.class,springmvcconfig.class}.
• used: @contextconfiguration(initializers = {springmvcinitializer.class}, loader=annotationconfigcontextloader.class) throw type mismatch: cannot convert class class>
• used: @springapplicationconfiguration(classes = {springmvcinitializer.class})

i think need set initializers instead of classes on loadingtests class.

@contextconfiguration(initializers = {springmvcinitializer.class}, loader=annotationconfigcontextloader.class) 

also please consider using constructor injection on dao.
