org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [repositories.UserDAO] is defined

Question

I am using Spring MVC and Hibernate.

I have a main Controller that deals with all requests. I have written a a test in order to test mySQL database connection with a simple example.

@Controller

public class HomeController{

@Autowired
private ApplicationContext applicationContext;


@RequestMapping(value = "/db")
public void dbTester(){

    User tester = new User();
    tester.setName("Ytesting");
    tester.setToken("ranodm");
    tester.setNumber("123456789");

    UserDAO userRepo = applicationContext.getBean(UserDAO.class);
    userRepo.save(tester);

}

When getting to the Second last line it throws this exception:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [repositories.UserDAO] is defined
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:982)

javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

root cause

I cannot figure out what the problem is.

my applicationContext looks like this:

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:mvc="http://www.springframework.org/schema/mvc"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context.xsd
   http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!-- This will define where the Dispatcher will look for a controller
 that has a Request mapping of "/" -->
<context:component-scan base-package="com.controllers"/>

<!-- This sets the default home page-->
<mvc:view-controller path="/" view-name="/login"/>
<!-- Sets the default path for all the Resources -->
<mvc:resources mapping="/resources/**" location="resources/"/>

and my UserDOAImpl:

@Repository

public class UserDAOImpl implements UserDAO {

@Autowired
private SessionFactory sessionFactory;


@Transactional
public User getByID(int id) {
    return null;
}

@Transactional
public void save(User u) {
    sessionFactory.getCurrentSession().save(u);
}

}

I just can't seem to figure out what the problem is

EDIT:

This is my ApplictionContext xml:

<context:component-scan base-package="repositories"/>
<context:component-scan base-package="services"/>
<context:component-scan base-package="controllers"/>

            <prop key="hibernate.format_sql">true</prop>
        </props>
    </property>
</bean>

<bean id="transactionManager"
      class="org.springframework.orm.hibernate4.HibernateTransactionManager"
      p:sessionFactory-ref="sessionFactory"/>

Correct the component can. it should include the package where the dao is located — Jens, Sep 15 '16 at 21:03
