Spring Security AuthenticationProvider No Bean Defined - spring-security

Question

I am implementing my own authenticator provider for Spring Security 3.1.4.
But when I running application on Tomcat I receive this log error from Tomcat.
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'myAppAuthenticationProvider' is defined
In web.xml y have this than others things.
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/applicationContext.xml,
/WEB-INF/myapp-datasource.xml,
/WEB-INF/myapp-security.xml
</param-value>
</context-param>
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
In myapp-servlet.xml y have this than others things.
<!-- Activa la configuracion de beans mediante anotaciones -->
<mvc:annotation-driven />
<!-- Activa la configuracion de los controladores mediante anotaciones -->
<context:component-scan base-package="com.myapp.**" />
<!-- Activa la configuracion de seguridad mediante anotaciones -->
<security:global-method-security secured-annotations="enabled" pre-post-annotations="enabled" />
In myapp-security.xml y have this than others things.
<security:authentication-manager alias="myAuthenticationManager">
<security:authentication-provider ref="myAppAuthenticationProvider" />
</security:authentication-manager>
Then, I have my authenticator provider like this.
#Component("myAppAuthenticationProvider")
public class MyAppAuthenticationProvider implements AuthenticationProvider {
private static final Logger Log = LoggerFactory.getLogger(AuthenticationProvider.class);
#Autowired
private UserService userService;
#Override
public final Authentication authenticate(Authentication authentication) {
final UsernamePasswordWithTypeAuthenticationToken authenticationToken =
(UsernamePasswordWithTypeAuthenticationToken) authentication;
String name = authenticationToken.getName();
String password = authenticationToken.getCredentials().toString();
String type = authenticationToken.getType();
if(isUserValid(authentication)){
List<GrantedAuthority> grantedAuth = new ArrayList<GrantedAuthority>();
grantedAuth.add(new SimpleGrantedAuthority("ROLE_USER"));
Authentication auth = new UsernamePasswordAuthenticationToken(name, password, grantedAuth);
return auth;
}else {
throw new BadCredentialsException("Bad authentication.");
}
}
#Override
public final boolean supports(Class<?> authentication) {
return UsernamePasswordWithTypeAuthenticationToken.class.isAssignableFrom(authentication);
}
private boolean isUserValid(Authentication authentication) {
User user = this.userService.getUserByEmailAndPassword(
authentication.getName(), authentication.getCredentials().toString());
if (user != null) {
return true;
}
return false;
}
}
Somebody can help me?, Thanks in advance.`enter code here

You have two spring contexts (first one for application beans / DS / security and second one for Spring MVC). Please make sure that your MyAppAuthenticationProvider is picked up in the first one by corresponding component-scan element. I am pretty sure that it is picked up by the second context (Spring MVC) and referenced from the first one, where it does not exist.
