jsf 2 - Spring Security:redirection to a specific page based on roles in JSF -

i work jsf , spring security. use custom login page. have 2 roles : administrator , user. question how redirect different pages different roles. example if user administrator, redirected "dashboard_admin.jsf" , if simple user, redirected "dashboard_user.jsf".

this spring security file :

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:security="http://www.springframework.org/schema/security" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://www.springframework.org/schema/beans                  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                 http://www.springframework.org/schema/security                  http://www.springframework.org/schema/security/spring-security-3.1.xsd">    <security:http auto-config="true" use-expressions="true">     <security:intercept-url pattern="/pages/**"         access="hasrole('role_admin')" />     <security:form-login login-page="/login.jsf"         authentication-failure-url="/login.jsf?error=true"         default-target-url="/pages/admin/dashboard_admin.jsf" />     <security:logout logout-success-url="/login.jsf"         delete-cookies="jsessionid" invalidate-session="true" />     <security:session-management         invalid-session-url="/login.jsf">         <security:concurrency-control             max-sessions="1" error-if-maximum-exceeded="true" />     </security:session-management> </security:http>   <security:authentication-manager alias="authenticationmanager">     <security:authentication-provider>         <security:user-service>             <security:user name="test" password="test"                 authorities="role_user" />             <security:user name="sam" password="sam" authorities="role_admin" />         </security:user-service>     </security:authentication-provider> </security:authentication-manager> 

this dologin method:

 public string dologin() throws servletexception, ioexception {      externalcontext context = facescontext.getcurrentinstance().getexternalcontext();      requestdispatcher dispatcher = ((servletrequest) context.getrequest())             .getrequestdispatcher("/j_spring_security_check?j_username=" + username                             + "&j_password=" + password);      dispatcher.forward((servletrequest) context.getrequest(),             (servletresponse) context.getresponse());      facescontext.getcurrentinstance().responsecomplete();      return null; } 

i find easy solution without using spring security, , works good. ravi
