why does annotate class as @Service do not create bean?

I has class like this:

@Service("userDetailsService") 
public class MyUserDetailsService implements UserDetailsService {
    ...

and trying to do:

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

and I got followin errors:

Cannot resolve reference to bean 'userDetailsService' while setting bean property 'userDetailsService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userDetailsService' is defined

Is it really necessary to declare bean? In that case like this:

<beans:bean id="myUserDetailsService" class="my.package.services.MyUserDetailsService" />

EDIT

Here is my security.xml file:

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/jdbc
           http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
           http://www.springframework.org/schema/security
           http://www.springframework.org/schema/security/spring-security-3.0.xsd">

    <http>
        <form-login login-page="/login/"
            authentication-failure-url="/fail/" />
        <logout logout-success-url="/" />
    </http>

    <context:annotation-config />
    <context:component-scan base-package="my.package" />

    <authentication-manager>
        <authentication-provider user-service-ref="myUserDetailsService">
            <!-- <password-encoder hash="md5" /> -->
        </authentication-provider>
    </authentication-manager>

</beans:beans>

which cause:

The matching wildcard is strict, but no declaration can be found for element 'context:annotation-config'.

just import the other xml file in the spring-security.xml by using <beans:import resource="" />

another thing u can do is that load all the xml files in the web.xml file using 

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
path to the xml files separated by commas
</param-value>
</context-param>

You are missing schema location for context.

So your xml should start with:

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/jdbc
           http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd
           http://www.springframework.org/schema/security
           http://www.springframework.org/schema/security/spring-security-3.0.xsd
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

@Service extends @Component which allows for classpath scanning.

You can enable both classpath scanning and annotations

<context:annotation-config />
<context:component-scan base-package="com.package.a,com.b" />

I don't know what version are you using. Try this.

<authentication-manager>
    <authentication-provider user-service-ref="userDetailsService">
        <!-- <password-encoder hash="md5" /> -->
    </authentication-provider>
</authentication-manager>

Unless you provide, as you do, a name, it will be the class name. But you provide the same name it would be but stating another in the config file.

If you @Service with no name then it would be fine.

If you use annotations to specify your beans, you need to have add an entry to your config to scan the classpath for them.

<context:component-scan base-package="org.example"/>
