java - Custom Authentication Provider on Spring Security 2 userDetailsService issue -

i had spring security 2.0.5 on webapp, using default provider. requirements have changed , need customauthenticationprovider in order change authentication way.

this authenticationprovider

public class customauthenticationprovider implements authenticationprovider {  @autowired private paramsproperties paramsproperties;    @suppresswarnings("unchecked") public authentication authenticate(authentication authentication) throws authenticationexception {      //check username , passwd     string user = (string) authentication.getprincipal();     string pass = (string) authentication.getcredentials();     if(stringutils.isblank(user) || stringutils.isblank(pass) ){         throw new badcredentialsexception("incorrect username/password");     }      //create sso     singlesignonservice service = new singlesignonservice(paramsproperties.getservicesserver());     try {         //check logged         service.setusername(authentication.getname());         service.setpassword(authentication.getcredentials().tostring());         clientresponse response = service.call();         string result = response.getentity(string.class);          objectmapper mapper = new objectmapper();         map<string,object> map = mapper.readvalue(result, new typereference<map<string,object>>() {} );         //read code         string code = (string)map.get("code");         log.debug(" ** [authenticate] result: " + code );         (string s : (list<string>)map.get( "messages" ) ) {             log.debug(" [authenticate] message: " + s );         }          if ( code.equals( "session_created" ) || code.equals( "session_updated" ) || code.equals( "session_verified" ) ) {                           usernamepasswordauthenticationtoken tokensso = loginhelper.getusersringtokenfromauthservice(map);                         return tokensso;                         } else {             return null;         }     } catch (exception e) {         e.printstacktrace();         throw new authenticationserviceexception( e.getmessage() );     } }   public boolean supports(class authentication) {     return authentication.equals(usernamepasswordauthenticationtoken.class); } 

and security.xml

<http>   <form-login default-target-url ="/login.html" always-use-default-target="true" login-page="/login.html" login-processing-url="/j_spring_security_check"         authentication-failure-url="/login.html" />     <http-basic />   <logout logout-success-url="/login.html" /> </http>  <beans:bean id="mypasswordencryptor"     class="com.mycomp.comunes.server.spring.core.mypasswordencoder" lazy-init="true">     <beans:constructor-arg>         <beans:bean class="org.jasypt.util.password.configurablepasswordencryptor" />     </beans:constructor-arg>     <beans:constructor-arg ref="paramsproperties" /> </beans:bean>  <beans:bean id="passwordencoder"     class="org.jasypt.spring.security2.passwordencoder" lazy-init="true">     <beans:property name="passwordencryptor">         <beans:ref bean="mypasswordencryptor" />     </beans:property> </beans:bean>  <beans:bean id="authenticationprovider"     class="com.mycomp.comunes.server.spring.manager.autenticacion.customauthenticationprovider"> </beans:bean>   <authentication-provider user-service-ref='authenticationprovider'>     <password-encoder ref="passwordencoder" /> </authentication-provider> 

but when deploying, following:

caused by: java.lang.illegalargumentexception: cannot convert value of type [$proxy112 implementing org.springframework.security.providers.authenticationprovider,org.springframework.aop.springproxy,org.springframework.aop.framework.advised] required type [org.springframework.security.userdetails.userdetailsservice] property 'userdetailsservice': no matching editors or conversion strategy found 

can help?

you refer authenticationprovider bean user service, not.

<authentication-provider user-service-ref='authenticationprovider'> 

with old version of framework, can guess way use custom auth provider correctly described here.

needless highly recommended upgrade, if nothing else, in order support easier.
