i implementing own authenticator provider spring security 3.1.4.

but when running application on tomcat receive log error tomcat.

org.springframework.beans.factory.nosuchbeandefinitionexception: no bean named 'myappauthenticationprovider' defined 

in web.xml y have 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 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 others things.

<security:authentication-manager alias="myauthenticationmanager">     <security:authentication-provider ref="myappauthenticationprovider" /> </security:authentication-manager> 

then, have authenticator provider 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 me?, in advance.`enter code here

you have 2 spring contexts (first 1 application beans / ds / security , second 1 spring mvc). please make sure myappauthenticationprovider picked in first 1 corresponding component-scan element. pretty sure picked second context (spring mvc) , referenced first one, not exist.
