Prosze o pomoc w sprawdzeniu o czym zapomniałem przy konfiguracji.Problem jest przy wstrzykiwaniu UserService do klasy Controller .Ponizej wrzucam:
1.Plik konfiguracja.xml

Czemu UserService opatrujesz adnotacją @Service ? Spróbuj na chwilę zmienić na @Component i sprawdź czy działa.

Sprawdziłem @Component jest to samo dalej dostaje

WARN : org.springframework.web.context.support.XmlWebApplicationContext -

Poza tym to nie jest tak, że są do wyboru adnotacje @Component, @Service, @Repsository i robią to samo a mają różne nazwy żeby w łatwy i szybki sposób odróżnić zwykły komponent od serwisu i od obsługi bazy danych ?

Teoretycznie tak, ale już raz to u mnie nie działało. W sumie wszystko wygląda dość poprawnie, ale spróbuj może je umieścić w jednym pakiecie ? Nie wiem czy "pl.konrad.apk" to na bank oznacza to "pl.konrad.apk*" .

Edit: To raczej nie to, jest wcześnie i kiepsko myślę. A nie trzeba było przypadkiem dorzucić konstruktora ?

Mógłbyś dodać jeszcze
<mvc:annotation-driven/>
Ale tak oprócz tego to na oko wygląda ok. Jesteś pewien że ten twój serwis jest w ogóle gdzieś w classpath tego projektu? ;]
(możesz też sklonować działający szablon -> https://github.com/Pharisaeus/SpringScaffoldApplication/ :P)

@Shalom rozwiń proszę - "Jesteś pewien że ten twój serwis jest w ogóle gdzieś w classpath tego projektu? ;]". Gdzie moge to sprawdzić ?

0

Najprosciej by było jakbyś podlinkował repo z tym projektem po prostu. Błąd wygląda tak, że spring nie znalazł tego twojego serwisu w trakcie tworzenia obiektów. Chyba że jestem jednym z tych geniuszy którzy wstawiają na forum "uproszczony kod", który, w przeciwieństwie do kodu prawdziwego, jest poprawny...

Czemu konfigurujesz to w pliku konfiguracja.xml jak masz plik src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml i masz tam

<context:component-scan base-package="pl.konrad.hh.controller" />

zmien na

<context:component-scan base-package="pl.konrad.hh" />

i zadziała

0

Extra działa. Czyli przy tworzeniu projektu stworzył mi sie plik konfiguracyjny servlet-context.xml a ja dodatkowo stworzyłem konfiguracje.xml i upychałem tam niepotrzebnie. No dobra a jezeli bede chciał dorzucić np bean entiityManagera,transactionManagera to zrobić nowy plik konfiguracyjny w META-INF czy skoro uzywam w wiekszosci adnotacji uzywac tylko jednego pliku servlet-context.xml ?

0

Ja bym używał jednego.
