java - Spring Security cannot find custom UserDetailsService -

i'm trying utilize spring security on app engine. implemented own userdetailsservice.

package com.example.mymodule.app2; import com.example.mymodule.repoobject.mutibouser; import com.example.mymodule.repository.mutibouserrepo; import org.springframework.beans.factory.annotation.autowired; import org.springframework.security.core.grantedauthority; import org.springframework.security.core.authority.authorityutils; import org.springframework.security.core.userdetails.user; import org.springframework.security.core.userdetails.userdetails; import org.springframework.security.core.userdetails.userdetailsservice; import org.springframework.security.core.userdetails.usernamenotfoundexception; import org.springframework.stereotype.component; import java.util.collection; import java.util.list; @component public class mutibouserdetailsservice implements userdetailsservice { private final mutibouserrepo mutibouserrepo; @autowired public mutibouserdetailsservice(mutibouserrepo mutibouserrepo) { if (mutibouserrepo == null) { throw new illegalargumentexception("mutibouserrepo cannot null"); } this.mutibouserrepo = mutibouserrepo; } @override public userdetails loaduserbyusername(string username) throws usernamenotfoundexception { mutibouser mutibouser = mutibouserrepo.findbyname(username); if (mutibouser == null) { throw new usernamenotfoundexception("invalid username/password."); } list<grantedauthority> authoritylist = authorityutils .createauthoritylist("role_user"); homecoming new user(mutibouser.getemail(), mutibouser.getpassword(), authoritylist); } }

but every time tired test app error.

'org.springframework.security.authentication.dao.daoauthenticationprovider#0': cannot resolve reference bean 'mutibouserdetailsservice' while setting bean property 'userdetailsservice'; nested exception org.springframework.beans.factory.nosuchbeandefinitionexception: no bean named 'mutibouserdetailsservice' defined.

can help me? thanks.

your problem has nil app engine fact spring container not able find bean named mutibouserdetailsservice.

i root cause component scanning configuration.

<context:component-scan base-package="com.example.mymodule"> <context:exclude-filter type="regex" expression="com.example.mymodule.*"/> </context:component-scan>

the class mutibouserdetailsservice define in bundle com.example.mymodule.app2, however, bundle excluded (see exclude-filter) component scanning , hence spring not register corresponding bean.

furthermore, there problem authentication manager configuration. follow excerpt below.

<authentication-manager> <authentication-provider user-service-ref='mutibouserdetailsservice'/> </authentication-manager>
