Unable to identify authentication-provider user-service-ref in Spring Security

Question

I am implementing spring security in my project

In my DAO class I am defining the loadUserByUsername

my class is like

UserDAOImpl.java

@         


        

Answer 1

Typically beans that are component scanned are camel-cased starting with a lowercase character so the bean would exist in the application context as userDAOImpl (not UserDAOImpl)

change your spring-security.xml snippet to

<authentication-manager>
    <authentication-provider user-service-ref="userDAOImpl">
  </authentication-provider>
</authentication-manager>

Hope this works for you.

Answer 2

phew... got it working.

Moved

<context:component-scan base-package="app.com,app.com.controller,app.com.dao,app.com.service,app.com.model"/>

    <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"
            p:basename="messages"/>

from dispatcher-servlet to application-context.xml

@Service("userDAOImpl") annotation on class name

Would anyone care to tell why it started working?
